Joe I love this build cant wait to get together in St Louis soon.

[JAMMER]

Joe these are great builds it a shame but I would have liked to have one of that dozer. Ed

[fhhhstix]

Glad to see you here Joe and I guess I'll see you in StLouis.

[RCLogger]

Looking forward to regular updates on your thread Joe

greg

[dirtpusher9]

Thanks guys, I'm looking forward to St. Louis.

Here's where I'm at on the scraper.

[dirtpusher9]

I'll try Greg, but it is 104 out right now and in the shop it's about 115. I need some cooooold weather. lol

[Roadmasters]

Looks great Joe!! Can't wait for more!

[RAIDERS]

LOOKING GOOD!!!

[RCLogger]

OUCH ! Joe it has been up to 33 C here which is about 91 F and that is too hot for me to go out and operate equipment in the sun. But 104 F ! I would be leaking like a Dam full of holes.... I feel for you !

greg

[dirtpusher9]

There predicting 108 tomorrow. It's just not fun to be out in that anymore, geuss I'm getting too old. Heat index (what it feels like outside) is 122.

[JAMMER]

Joe in that kind of weather you better watch it we don't need you to go down again your no spring chicken any more. Ed

[dirtpusher9]

Thanks for reminding me Ed. lol

[fhhhstix]

I feel for you I spent all last week in 95 deg heat wearing a leather welding jacket repairing a material handling bucket. For those that don't know what a material handling bucket is it is a light duty over sized bucket ment for light weight material such as mulch or corn glutin. That is suposed to be a winter project not during a sever heat index warning.:(

[dirtpusher9]

That just ain't right Travis. A man shouldn't have to work like that. I guess I'm spoiled being in a 140h with ac all the time.

[dirtpusher9]

Joe these are great builds it a shame but I would have liked to have one of that dozer. Ed

I had several people wanting me to build them a dozer like mine, so after Indy last year I wrote Cat to see about licensing. They emailed me and said that do to the economy that they weren't doing any licensing and besides it was very exspensive, but they liked the one-off. So I just forgot about it. A month later I get an email from the top model builder of Cat models in the world, CCM (Classic Construction Models). They said that Cat had suggested that they (CCM) let me build under there license and they would market them for me. I'M ON TOP OF THE WORLD RIGHT ABOUT NOW. We talked on the phone a couple of times about how we could go about this. They finally emailed me the other day and gave me the details on what they were willing to do and the bottom line is that there is no way that I would make anything on these models, in fact I would go in the whole bad on each one by the time they took 10% off the top for Cat and 20% for CCM and my labor. So I guess I just build one-offs, but I thought it was quite something to even be recognized by both of them. I didn't expect to even hear back from them when I first wrote them.

[Lil Giants]

Send some of that heat/sunshine here plz, I should be harvesting by now, not wearing a raincoat.

Looking forward to the videos of these pair working in tandem Joe. :cool:

[ihbuilder]

hi Joe this 1 great build , can't wait to see it in st. Louis :D

IHB

[Lil Giants]

Yeah, the builder of the model always gets the short end of the money tree. :rolleyes:

[modelman]

Hi D9joe-thanks for letting my know about the new site!

[dirtpusher9]

It wouldn't be the same without you Tom.

[td9clyde]

Glad to see your workin on your pan more but i am like you i don't do much in the heat lol been hot here too the ts 14 has made a lil progress not much since my equipment went down i am in the market again for a 3 in 1 tool lol

[dirtpusher9]

What happened Henry? Did you ever get the dozer all finished?

[JAMMER]

Joe it looks like it coming together. Ed

[dirtpusher9]

Got to work a little today on a small new project for the dozer, should have some pics in a day or so.

[dirtpusher9]

Well we had a cool front (under 100) blow in, so I (sweat-ed) worked in the shop a couple of days
.
Most of you know that When I built my dozer I made a winch for it that looks like this.
http://i539.photobucket.com/albums/ff355/dirtpusher9/FINISHED002.jpg
Well, since I'm building a scraper I thought it would look better if I built the detail on the back of the dozer and made a drawbar to pull the pan with. I still need to make the hitch and a few other little details but I think it will look a lot better this way. Been wanting to put the detail on it since I built it so now was a good time.
http://i539.photobucket.com/albums/ff355/dirtpusher9/HPIM1359.jpg
I hoping it will resemble this when complete.
http://i539.photobucket.com/albums/ff355/dirtpusher9/681.jpg

[modelman]

Hey joe- nice work! The only problem is that we never got to see you "jerkin" on anything with that winch! I bet that dozer & winch could pull up a small tree stump!:D

[td9clyde]

i sheared a drive or something lol or gear there are chuncks of something in there lol

[td9clyde]

oh yea and no the dozer isn't done i am still needing to buy esc's and radio and batteries lol i did get the 82-30 on the side of the hood looks almost done

[CatdrvR]

As I said on scale4x4, absolutely awesome build! I love that bulldozer and wish I had one of my own. How long did it take you from start to finish to complete it? As always, can't wait to see updates from you in the future. You are definitely a talented builder.

Dan

[dirtpusher9]

Thanks for the kind words Dan. It took 2.4 years rainouts and weekends to build. it seems like I've been working on the scraper that long too.

[JAMMER]

Joe one of the reasons they contacted you because I kept bugging them about the 1/12 scale they were sappiest to have and kept telling them about your. O well can't say I didn't try. Sorry it didn't work out. Ed

[dirtpusher9]

Not following you ED????????

[JAMMER]

I kept calling them and asking about there 1/12 scale dozer and they said it wasn't done yet. I told them that they should go on you tube and see dirtpusher9 video that dozer could push some dirt for a model. I also said Cat had contacted them about you and your dozer and if they did work out a deal on it I sure would want one and I know a number of guys that would want one. Ed

[Tamiya Cowboy]

Joe that draw bar looks great nice work.

[rc_farmer]

Joe that is great to be reconized by both of them. Cat is very hard to get licensed by. The 10% is the usual take, but for the other Co. to want 20% is rather high. You do GREAT work!

[dirtpusher9]

Thank you, Paul.

Rob, with the 20% for the model company, they give there distributers a 10% discount.

[JAMMER]

Joe your transmission cover and draw bar look real good keep it up. Ed

[trucker n]

nice

[tracksntreadslou]

Nice to see you back on the build joe...You havent made any new vids lately...Isnt it about time ? lol..:rolleyes:
I was over at the german construction forum that Gabreil has his D11 on and am a member there too ..I sent him a message about this place as well and hope he signs up ..

[dirtpusher9]

Thanks guys.

Lou, I figured everyone is about tired of seeing the dozer just push some dirt around.

I seen that he signed up the other day, under a new name.

Should have some pics in a day or two of some new junk.

[Southgate]

nmbxnjjjjjjjmccccccccccccccccccccccccccxxxxxxxnnnn nnnnnnnnnnnnnnnnnnnnnnnnbbnmmmggggggggggggggbbbbbb bbb

Oh! Sorry...That was my jaw flopped on the keypad. I'm new here, and only beginning to see a whole new world of crazy cool stuff. That is outstanding work! I'm kinda stunned...

RC racing has never really appealed to me, but heavy equipment? I know I don't have to tell you guys about that. RC Heavy equipment? I mean HEAVY rc heavy equipment...Words fail. Dan

[td9clyde]

I can't wait to see more pics and video's Joe the back trans plates and draw bar looks awsome !!!! great detail and awsome workmanship

[dirtpusher9]

Thanks Dan and Henry.

Finally finished the drawbar and tranny detail.

[FabOne]

Nice SCRAPER Joe. Very impressive. I really like the older scrapers.

[RCLogger]

Right On Joe
Your CAT is great, can't wait to see it pulling.

greg

[dirtpusher9]

Thank you guys ,hope to have some pics on the scraper pretty quick.

[modelman]

Joe-the rear detail looks great! That drawbar should handle lot's of pull power on the scraper!

[td9clyde]

pan pics pan pics pan pics PLEASE lol maybe a moc up shot with the 9???? please :)

[dirtpusher9]

Maybe this weekend, maybe if I get a little farther along. I am getting close though.

[rc_farmer]

Joe, i, for one never get tired of seeing anything you build. Can't wait to see the pans

[Espeefan]

Joe, I love this build. You guys building these Cat dozers make me wish I had the same level of skills. I'd build my own, if I could. Seems to me the hardest thing is to try and locate some good drawings. What do you work from, when you scale down and machine the parts? Blueprints, or service/part manuals? It looks so excat and perfect. Beautiful. Can't wait to see the scraper done too.

[dirtpusher9]

Thanks guys. Nathan, I went on Cat site and downloaded the brochure on the D9R and blew it up to 1/10 scale and downloaded a whole bunch of pics off the net and went to building. Had a hard time trying to find the pics I needed for the scraper's rearend so I more or less faked it. I do most of my building by eye, which is steadly becoming a problem. This is the first time I ever attemped anything like this so it has been a learning experience from the word go.

[J Hall]

Hi Joe...Thanks for the note over on U-tube..Yes the motors are very silent..Now if I could just find a winch motor that is as silent insead of that noisey thing that is in there now..

I did get a guy to haul in 2 loads of yellow clay ( 20 yards plus ) so now I have better stuff to push around and it is just outside my shop..Been bus building a locomotive for a public display so haven't had much time to play around...Maybe tomorrow I can get a photo or two..

The D9 and scraper are awsome...Love to see it load some dirt..

Jerry

[Ace Trucker]

nice machines

[dirtpusher9]

Thanks Jerry and Ace. Glad to here you have your own dirt pile to play in Jerry, there's nothing like going and just hogging some material around with the miniature equipment.

Well I had said that I might have some pics up this weekend, however I had a semi major malfunction. I was just fixin to put a final coat of paint on the neck of the scraper and broke the soldier joint on the top of the neck that was a hinge to open the neck up to hide hydraulics in when I was going to make the scraper a self contained unit. When it broke that little part of the joint I decided to tare it completely off and weld it solid to the rest of the neck. Because I had done away with the idea of hiding the components in there anyway. So needless to say all that grinding and welding messed up a bunch off the neck paint so it set me back. But I think it looks better now anyway. I should have never trust my soldiering skills in the first place , not a strong suit of mine. lol

[td9clyde]

well i would look at it like this better now than later ........at least i know when your done it will look good and you will let us have a peek lol

[dirtpusher9]

Well besides getting a few hydraulic items in that I ordered and hooking every thing up, this project is just about completed.

The pan looks great now how soon before you start building another dozer to push it? Ed:D

[modelman]

Looks fantastic joe-can't wait to see it working!!

[J Hall]

Very nice...Too pretty to go out and get it all dirty..LOL
What do you think the weight would be ??

[Iron Art]

Lookin' good Joe, another great build, I too can see a push Cat in the future. So much to build, so little time. Fred

[Tamiya Cowboy]

Joe I just ran accrossed this over on scale and WOW you really have a eye and skill for building..I wish I had half of your metal talent!.

[td9clyde]

Awsome job!!!! glad to see some yellow paint they way things are going we and yes i said we might be moving some dirt before long lol glad to see you about completed on the pan whats next??? i know you shurly have a couple ideas after tires being a hard item to come by i think i am going to stick to tracks like i said though glad to see your pan looks great Joe

[Lil Giants]

Very nice...Too pretty to go out and get it all dirty..LOL


BALONEY!!! What makes them "pretty" is the battle scars. :cool:

Stellar looking model Joe, wouldn't expect to see anything less than perfect come out of your workshop... now lets see it go to work! :D

[dirtpusher9]

Thanks guys.

Scraper is 42''and it weighs 48lbs. Over all length is 69''.

Henry not sure what I'm going to build next (if anything), the way the tire situation is, if I do another build it will more than likely be tracked.
Here is the whole setup. Not real happy with it behind the dozer, it just looks to small to me. Still not sure if the thing is even going to work or not, I guess if it don't it will make a good paper weight.

[td9clyde]

looks good from here well i hope to see you continue to build your work is undeniable some of the nicest around can't wait to see if you build another dozer or something kinda like to see you build a low tracked version of an 8 or a 9 or something

[Lil Giants]

The only problem I see Joe is that it looks too clean! Once it's dirty and scarred up like your dozer, they'll definitely look like a matched set. ;)

An excavator or wheel loader or mid sized haul trk would be a nice addition to your fleet. The scale you're building in, a finnish grader is possible. ;)

Also, start dreaming of a dirt work project to put them to work... how big is your backyard? Dig a swimming pool maybe... then fill it back in again. :D

[FreddyGearDrive]

I've been missin the boat on this build,WOW, That build is perfect! But,wouldn't expect anything else.Not after turning the landscaping up side down in minutes w/your first piece of art you made. Keep up the good work!
FGD

[dirtpusher9]

Thanks you men that means alot.

Joe, I would like to do a blade but the tire thing keeps blowing out of the water. Also thought about a 988 loder, just need tires.
I just ran a few numbers on a 385 trackhoe, it would be HUGE AT 63'' in length with the boom folded up and set on the ground. It would look ever so cool. So I'm not sure what to do, besides I told my self after faking so much on the scraper that the next thing I build, I will have all the pics I need in order to do it right. There aren't any around here to get enough pics of.
http://i539.photobucket.com/albums/ff355/dirtpusher9/DSC02265201024x76820640x480.jpg

I have a big yard but I also have a big mean wife that would kick me in the pants. So I wont be digging any pools. lol (just kidding honey if your read this)

[JAMMER]

Joe you better be careful or she will take your aspirin away an won't let you run around the block. ed. Ed

[RCLogger]

WOW Joe your iron is so cool. I doesn't matter what you build next, just get-at-er. I do think you need something to load dirt ...

greg

[Espeefan]

Boy that scraper looks great, even if it's not a 100% accurate. I sure can't tell. That is every bit as amazing as the big old Cat D9. Definitely a great combination. These are some serious machines!

[td9clyde]

lol i have thought about that too more like a 225 but if i build it it would be out of all metal and the boom and stick would be heavy i would have to make them out of aluminum to get the performance out of it and the rest could be steel so i donno if i will be building one and joe if you need pics let me know i can get them and i can get measurements...........D6 N would be a good one 6 way blade and a nice tractor to boot

[Lil Giants]

What would be the dimensions for your grader tire? Would a hockey puck be close? Somebody mentioned that it would be possible to buy any sized diameter of a hard rubber solid cylinder to make tires from...

I think you're taking this "scaled model building" too seriously Joe... you get within 75% accuracy and IT WORKS TOO! what more could anyone else say but well done?! You don't sound like you're enjoying this anymore...

I think I've seen your wife in one your videos, cheering you on while you're showing off newly built D9... I wouldn't believe that she'd chase ya down with club for digging a little wee hole in the backyard? :p

[SonoranWraith]

I know they aren't on this side of the pond, but there are quite a variety of sizes available. My guess is that in 10th scale they are small? There are some european semi truck sites that deal in 1:12 stuff you could make work. Equipment wise everything is tailored to 1/16-1/12. :(

Thanks for all the complements guys.

Joe, I may have found a tire that will work, just need to get some more measurement's before I know for sure. I thought about the solid robber when I was researching for the scraper build but 7'' solid rubber chucks are no where to be found. I already had found a grooving iron and a guy to cut them, but no rubber.

I enjoy the building part except for not being able to be accurate in the making of parts that I can't see and know for sure how they are suppose to look. And the showing of the model bothers me because there are so many that make beautifully machined pieces. Seems that the manufactured models and the perfectly scaled models are what intrest people the most over something done by eye and faking. I just am the type person that wants it right if I'm going to call it scale and show it to the world.

[ihbuilder]

I don't Know about scaling perfectly but a couple of your vids with the D9 I'd swear it's the real machine . I think you're doing a fine job with the detail :chug: some time the scaling can be trouble some like I found out I got the necks to short on my scrapers cause I couldn't find dim. so I scaled the comparable cat (627) and improvised

IHSteve

[td9clyde]

yea i get what your saying on wanting the true scale of the parts and wantiing the whole thing acurate i do agree but if you look at mine it is as true as i can build at this time and i messed up on my scraper too on the neck even the second time around i made it too short cuz of the pics i had and there was no good way to get an acurate measurement i wound up stretching the neck onit the other night and things didn't line up so they are as close as i can possibly get it when i am finished it won't be seen ....it's a model and usually models are a close resemblence get a plastic car model if you really look at them they are just a close resemblance not completaly acturate ......sorry my spelling is so bad Joe all in all i think your models are a great thing to look at and i can only wish to have half your skills and talent your dozer and your scraper looks great and i know your dozer works great can't wait for video with the pan keep up the great work i always look forword to your builds they are always done with great acuracy even if some parts are as you say faking them they still function all we can do is get them close and if we enjoy them thats what they are for

[dirtpusher9]

Thanks for the boost, Steve and Henry.

Sorry for the late reply guys but I have been playing with my new Grandson (5 lbs 2 oz.) man he is amazing.

Still waiting on my quick connects, there was a little problem on there end but the rest is ready when I get them. I'm ready to see if it is going to work right and heap up a load.

Can anyone tell me what size screw the pressure adjustment is on the pump, and how much to turn it up? I had that info on the gt forum but........

[td9clyde]

congradulations with getting a grandson I found rubber stalk it is in a few sizes i can give you the all the sizes if your interested but they come in 2 feet by 2 feet and only a few thicknesses 1 inch 2 inch 3 inch the 3 inch 2x2 is 160 $ i don't think it is that bad that and given the fact for me to get it is cash and carry lol and the place makes it so it is plentiful

[dirtpusher9]

Thanks, HENRY.
Got 4 of these in earlier.

Hey Joe You may want to hook a gauge and do a little trial and error and see what works best..There is an metric allan screw underneath the cap screw but cant remember the size...should be pretty easy to find the right one that fits...I went about a 1/4 turn at a time til i thought the pressure was satisfactory...When i first was using my hoe The boom cyclinders had trouble lifting up the front of the tracks..i probably should have used a guage..Im hoping that leimbach pump will be able to handle that ejector..thats going to br quite a bit of weight...Clippard has a formula in there catolog that give you an idea of what kind of pounds those cyclinders will produce @ ? psi ..anyway i will wish you luck and hope it works out well

Hey nice little couplers ..are those double shut off and where did you source them?

[dirtpusher9]

My problem is the size of the allen screw, I beleive it was striped when I got it because nothing will fit it, too big or too small.

The ejector has been my biggest fear all along on this project. It rest totally on bearing and moves very easy but I think one grain of sand get's in between their and the bowl and the cylinder is going to struggle.

The quick connects are double shut-off from Rectus Tema. They are 3mm ID x10mm OD, will operate up to 250 psi. and max is 500 psi. 1.5 gpm flow. Their nice little units.

[td9clyde]

Joe, i for got i was gonna see if i could talk you into a hook on the rear of your pan so then i could push with the 14 to help load your pan then you could pull the 14 to help load it lol ....we would have to do some measuring on your push block highth and the front end highth of the 14 so i would know where to place the bail on the front or i could just make it adjustable i guess lol

[chaseracer]

wow, amazing work, I have been following these builds from the other forum.
I can't get enough your dozer, that thing is awesome. great job keep the builds comming.

[tracksntreadslou]

Hey joe now that you mention that greg and i had problems setting up my last pump...Theres a chance it could be torx as well...I think we ended up using a small flat screwdriver ...i think they were set factory so people wouldnt mess with pressure

[Lil Giants]

I think it's a #7 torx... I have both metric & sae allen wrenches, I forget which one I used. Yeah, as Lou said, it's Leimbach's way of making their pumps tamper proof. Great idea Lou to use a small flat tip screwdriver. ;)

All this talk about "push/pull" with two different rc machines reminds me of the radio interference problems you guys will likely have with rubbing metal surfaces of two different models together.

I had trouble with my KH dump trk & pup, had to add a wire screwed to the tongue on the pup with a female slide clip & screwed a flat piece of metal to the hitch plate on back of trk so the two pieces were permantly grounded all the time. Otherwise, the slop in the pintle hook & loop caused the trk to go crazy.

You may have to do add a grounding wire to your dozer/scraper Joe.

Whenever I get my own scraper functional, I was thinking I'll slide a piece of pvc tube over the rear push bar on scraper so when the dozer pushes, the pvc will act as an insulator between the metal models.

Would the RC interference be a problem while using the 2.4GHZ radio's???

[D8R]

Good choise of connectors, Joe. As you know I have same for my D8, use them both for Scraper/ripper and blade (have to remove blade to get machine out of work shop). They have a 6mm version but then only the female connector has shut of function.
I don´t follow the problem with r/c in 2 models, are you supposed to have seperat radio for scraper? If not, I can´t see the problem.
The IMC models of D11 was shown in their video pushing double heading without any problem. Back in those days it was normal radios (35mhz or).
Dan

[Lil Giants]

I don't know Steve. If 2.4 is the answer, then I'll be buying all new radios. ;)

It's just what I've experienced with my own models Dan. Even if I bump the bucket of the excavator or wheel loader on the metal box of the adt, sometimes either/or or both models will glitch.

[JAMMER]

Joe how are those quick connects working out for you? I see you got it all painted up how close to done are you? You will have to put a heavy piece of plastic on the push bar so Henry can push you if the going gets tough. Ed

[dirtpusher9]

Joe, i for got i was gonna see if i could talk you into a hook on the rear of your pan so then i could push with the 14 to help load your pan then you could pull the 14 to help load it lol ....we would have to do some measuring on your push block highth and the front end highth of the 14 so i would know where to place the bail on the front or i could just make it adjustable i guess lol

No Henry, these weren't meant for that setup, just going to leave it like it is. Besides, it's has enough design flaws.lol

wow, amazing work, I have been following these builds from the other forum.
I can't get enough your dozer, that thing is awesome. great job keep the builds comming.

Thanks chaser.

Joe how are those quick connects working out for you? I see you got it all painted up how close to done are you? You will have to put a heavy piece of plastic on the push bar so Henry can push you if the going gets tough. Ed

Hooking them up this weekend and give it a test run.

I don't see having a problem with interference with just the scraper, because it is just hydraulics going to it. There is no electics in the scraper.

[wayne9428]

Hey dirtpusher why can't you modify the body and the tracks and make your own model that will be a dirtpuser special

[wayne9428]

Joe that is great to be reconized by both of them. Cat is very hard to get licensed by. The 10% is the usual take, but for the other Co. to want 20% is rather high. You do GREAT work!

Why can't you just modify change the body and do some modification to the tracks andmake your own model and call it the dirtpuser special.

[dirtpusher9]

Why can't you just modify change the body and do some modification to the tracks andmake your own model and call it the dirtpuser special.

I think they look a lot better when they resemble the real thing.

I got this thing working except that the crowd want's to move first then the apron do to path of least resistence.(they work off the same valve) So it will cause problems loading and unloading but I have one idea to try tomorrow if that don't work I don't know what to do short of puting another valve in but it wouldn't be proportional. Any ideas?

looks sweet Joe , Now get some dirt in it :p . Off the top of my head , restrict the flow to the apron . If that makes sense :o

IHSteve

[pugs]

Looks great!

[Snochaser]

That was my only thought. Looks good. Get that dirt rollin' over the sides!!

[dirtpusher9]

looks sweet Joe , Now get some dirt in it :p . Off the top of my head , restrict the flow to the apron . If that makes sense :o

IHSteve

That's a good idea Steve. Have to get some more fittings.

[JAMMER]

Joe that looks great and as far as your problem how about a valve in the with a servo to cut off or reduce the flow, it will go to the least resistance. Ed

[9W Monighan]

That's a good idea Steve. Have to get some more fittings.

On the cable scrapers I've run you pull on the lever and the door opens and then the ejector pushes forward. Then when you push the lever away the ejector moves fast to the rear before the door closes. You may need to put a needle valve that meters in one direction and free flows the opposite. So you may need two to dial in both functions. I have a small 4-1/4CY Soil Mover scraper that has a valve body in the lines to regulate the flows.

[Lil Giants]

Mine has rubber bands on the ejector so it doesn't move forward till the crowd is all the up.

[dirtpusher9]

Here is a video of what it is doing.

http://www.youtube.com/watch?v=LGpi0BcaCnc

[td9clyde]

Hey Joe try it in the dirt first you get a load in it it should hold your ejector back i would try it in the dirt might work then

[ihbuilder]

Mine has rubber bands on the ejector so it doesn't move forward till the crowd is all the up.

joe ejector is the crowd apron is what you mean , I think .

Joe DP9 , what joe did will work try that or play with some springs till you get the right tension before changing the hydros . Also , just a thought on keeping the dirt out of the crowd roller path , see if you can put some kind of rubber wiper on the crowd to keep the floor clean . I've been thinking of this for my 2 $scrapers .

IHSteve

[Tamiya Cowboy]

Looks great Joe a true work of art for sure. I think what Steve is saying will work or the dirt in the pan. It looks in the video that there is more resistance in the cylinder for the gate then on the crowd.. Springs holding it back or a valve block restricting the oil flow to the crowd should fix the issue.

[pugs]

Do they make sequence valves small enough??

Otherwise you could put pressure relief valves in the gate cylinder lines (and a check valve in each as well), but have the dump of the pressure relief valve run the crowd cylinder instead of being a tank drain. This way the Gate cylinder would open fully first, then the relief valve would allow fluid to the crowd cylinder. Need the check valve in the non pressurozed side to allow fluid from the rod end of the crowd to bypass the pressure relief valve on the rod end of the gate cyl and return to tank. Same thing in reverse.

I'll see if I can't draw up a schematic quick of what I mean.

[pugs]

A crude drawing but it should work. Only downside is the the crowd will retract after the door goes down. If you want that to be reversed then just switch the relief valve and check valve directions on the rod end of the cylinders to make the sequence that the door opens first and closes last.

As drawn the door opens first and closes first. The pressure reliefs would be set just a tad higher pressure than is required to operate the Gate reliebly, but also under system pressure.
http://i839.photobucket.com/albums/zz317/JPMach/Misc/DSCN0482.jpg
I'm not sure what is all available in the small hydraulic valves and such, so hopefully there is something you can fit in.

[ihbuilder]

you don't want to much resistance . just enough to get the apron open when empty . when loaded you'll have plenty of resistance :)

IHSteve

[jffhrvstr]

Nice work on the dozer & scraper!

[D8R]

Can´t wait to see it working!
For my own calculations, have you messured drawbar force from machine?

[rc_farmer]

Joe your pan is looking mitty fine.....can't wait to see it in Stlouie

[modelman]

Joe-your scraper looks great! I'm sure you will get it worked out. Can't wait to see it load & unload!

[dirtpusher9]

Thanks guys, it wont be long now. I put it in the dirt and MAN it does good, dozer has plenty of power, it loads like a dream, and a BIG bowl full. However the only problem is that the apron gets dirt hungup in between it and the bowl, not letting the apron move. So I think I'm going to cut the apron sides down a little and see if that helps. Going to put a stiff arm on the apron too and maybe it will force it some. I think once the apron is working right, it will solve the resistence problem. The crowd didn't hang up at all like I had thought it would, so that made me feel better. Steve, I have leather sweeps in front of the crowd too keep the roller track clean.

Dan, the dozer will push a little better than 200 lbs, not sure on the drawbar pull yet.

Thanks for all the imput guys and the drawing Jeff.

Hope to have a video soon. It looks so cool running around, not rubbing it in, just excited.

[SmallHaul]

Wow, your scraper looks great! Even just the vid of it running on the bench looks cool.

Very nice work. I can't wait to see it full of dirt.

[D8R]

Joe, can´t wait see it in action. What´s the weight of the D9? Do you have a pic on that leather sweep and will you put in some similar in the apron?
Sorry for all question but you are running into problems that I could expect to happen with my models, guess I just sitt and wait for you to solve it, just kidding!
It´s project like this one and others on this forum that keeps myself trying to get something done,
hat of, I ´m impressed.
Dan

[td9clyde]

awsome Joe that is really cool i can't wait to see the videos and more pics and then what might be the next build???? lol very nice work

[dirtpusher9]

Thanks guys, the dozer is 97 lbs. Dan. I'll try and get a pic on the leather strip up soon. Not sure what I'm going to do on the apron yet, probly play with a few things.

Still running some numbers on the next build, Henry but I have narrowed my options to 2 machines. Now just got to deside which one.

[td9clyde]

Awwww well i bet i know the 2 choices 6 tires or tracks that pivot lol

[dirtpusher9]

Here is a really short video of the scraper loading. Still working on the apron issue, so I won't be showing the unloading fiasco. lol

Congratulations Joe!

It looks and works awesome.:cool:

[Iron Art]

Joe, Great build, looks so real with all the detail that you have built into the finished project, Congrats!!! Fred

[dirtpusher9]

Thanks for the kind words fellas.

Well I have the apron fixed now, it looks cobbled together but it is going to have to due. Will get a video of the full meal deal up soon.

[Young_DieselRC199]

Thanks you men that means alot.

Joe, I would like to do a blade but the tire thing keeps blowing out of the water. Also thought about a 988 loder, just need tires.
I just ran a few numbers on a 385 trackhoe, it would be HUGE AT 63'' in length with the boom folded up and set on the ground. It would look ever so cool. So I'm not sure what to do, besides I told my self after faking so much on the scraper that the next thing I build, I will have all the pics I need in order to do it right. There aren't any around here to get enough pics of.
http://i539.photobucket.com/albums/ff355/dirtpusher9/DSC02265201024x76820640x480.jpg

I have a big yard but I also have a big mean wife that would kick me in the pants. So I wont be digging any pools. lol (just kidding honey if your read this)

lol good thing you were kiding other wise ITS THE LIVEING ROOM PAL or the shop ethir one lol

[dirtpusher9]

You got that right, Dalton. I don't want either one.........(again)

[D8R]

Looks realy good Joe, hope I can have a video to show someday, I feel like a slow builder comparing to some of you guys. But results like yours here makes me try harder.
keep it up, looking forward for more videos.

You got that right, Dalton. I don't want either one.........(again)
hahaha AGAIN........?! what you do track mud in the house hahaha

Dan, here is a pic of the leather sweeps to keep the roller rails clean.
http://i539.photobucket.com/albums/ff355/dirtpusher9/HPIM1469.jpg

I had planed on making a video today but had some problems when the dozer through a drive chain on one of the motors and all that torque is good until the chain raps up on the sprocket and then it gets ugly quick. Burnt up some small ground wires and twisted the motor around in the mount. But it is all fixed now so maybe when my nephew comes down next weekend I can get another video. Unless I can get my wife to do a video for me sooner.

The new apron works well except for the side of the apron are still binding so I'm going to cut them down and that should fix that little problem.

[dirtpusher9]

Joe, I know that you discussed the need of some sort spring for the tracks, do you, or some one else know how much force this needs to have??

I was going to use high performance valve springs out of a Harley but just woundup just using 2 set screws on each side.

Someone had asked me what scale this is in, it's 1/10.

[J Hall]

1/10 scale...Thanks Joe

[W900snowman]

Dirtpusher9, I'm new around here and am very curious about about the tracks and under carriage on your CAT. Did use roller chain or??
Thanks Love the setup.

[dirtpusher9]

I used 1 1/4'' x 1 1/4'' x 1/8'' ''T'' steel for the tracks, 13 different operations per pad.

I used double pitch half links for the rails.

[W900snowman]

Ok, Thank you very much. That's a big help

[ihbuilder]

Joe , you told me on GT and I didn't save it :mad: , where did you get the T bar ? I google it and get a whole bunch of BS . :mad:

Thanks Steve

Joe sorry to hear the Cat through a chain what caused that? Have you got all the problems with the pan worked out? That video you took looked good. Ed:cool:

[ihbuilder]

Steve, You need Tee bar? I have tons of it. What size?

Steve , to do what joe did ,I would need the same size 1.25 x 1.25 x 1/8 . prob is I have this want to make them look exactly like the real pads . I'm thinking of putting a horizontal mill cutter on my lathe w a vice on the cross feed and mill them . unless your up to it like you did for your I beams :p How big of T do you have ? PM or call . I could do what I want ,with 1.5 or 1.75 would be easier . got this project just about off the drawing board just some lil details . Sorry Joe I'm hijacking :o

Joe, Your outfit looks so real I had to study it to make sure it was a model. You know it would be kinda interesting to have a thread on the best videos of the various builds to be voted on by the participants of the forum. Maybe each member if interested could enter their best video over a period of time and then have all members if interested vote for the best overall. Could be the best of the year or some other time period. Just an idea. Fred

Fred, I like your idea, we need more inspiration on here and that might just do it. One of you mods bring that up next board meeting, please.

[td9clyde]

great job!!!!!!!!!!!! looks like it does the job and looks real and good too how big of a cut are you taking at a time in one pass ? looks like you have plenty of power and traction i am curious how much preshure of a pull it is making and how much it weighs loaded just curious definitly another great build keep up the great work

[Tamiya Cowboy]

Joe that is great it looks like it works perfect just like the dozer does. Looks to be cutting very nice as I am sure it has enuff weight.. Great job another perfect build!

[9W Monighan]

WOW That looks excellent! The lighting really does it justice too. By the way; Are those leaves from some giant prehistoric tree of some sort:D:D:D

[dirtpusher9]

Thank you guys.

It will cut about a 1/2'' at a time but that is because the cylinder bottoms out. However after today it may get new cylinders that will dig a little deeper.

Been going to try and build some cylinders for about 2 years now, well today I successfully made one and put it on the scraper. The crowd cylinder that I bought was a 6'' stoke and I needed 7'' so I hooked it up and it works really well. I was wanting the crowd to move faster as well so I put a big ram in it and it doubled the speed of the crowd. I'll get better pics up of it all tore down, it is totally rebuildable through the gland end.

http://i539.photobucket.com/albums/ff355/dirtpusher9/HPIM1538.jpg

[td9clyde]

thats cool i was going to do the same thing on the tilt cylinder for the D7 and 82-30

[fhhhstix]

WOW Joe it doesn't look like you are going to need the push bar on the back of the pan the 9 does a good job of filling it on it's own.:cool:

Travis

[modelman]

Well joe-you gonna show us how you made the cylinder or is that "top secret".:D

[td9clyde]

yea we need a step by step and where to find the parts lol i was going to bore mine out and have them nichol plated and the stem chromed and just use O rings in it

[dirtpusher9]

Well joe-you gonna show us how you made the cylinder or is that "top secret".:D

Don't tell anyone Tom.lol

Here is the cylinder all torn down. The bore is 1/2'' and stroke is 7'', with a 5/16'' ram. The material is all from McMaster-carr.

[pugs]

Great looking work

[9W Monighan]

Yes, Very nice machine work Joe. What size threads are on the packing flange?

[td9clyde]

why can't a guy use regular metal like cold / hot rolled steel for what we are doing? and hone them real fine inside?? would it work? i was thinking i would have the inside and stem nickel plated but it would be nice not to have to do all that when boring and honeing would work i mean how much hydralic preshure do they push ?? in psi i know 10 bar or so but i donno what that actually is lol and i know it has to be smooth right? any detailed help would be great:) that is one nice pan and cylinder you have built very cool

[dirtpusher9]

10 bar is 174 psi. The steel will work if seemless and honed. I useed the brass because it machines better and and the price is'nt much different. I haven't even honed this brass yet. Most tubing I've seen don't take much to clean up. I used regular o-rings on mine and is doing fine so far but I'm ready to put it to work.

Steve, I used 1-72 bolts on the gland packing.

[modelman]

Joe-that is some nice and precision work! Will the standard o-rings handle the hyd. fluids?

[td9clyde]

well i was going to use round stalk lol as like in my pics that i turned out no seem i don't think lol and i think i could use a set of fine brake hones and on the stem what could be used zink plated ? i really don't know i know how it all works just don't have a clue what to use for materials ............sorry about hyjackin your thread

[dirtpusher9]

Joe-that is some nice and precision work! Will the standard o-rings handle the hyd. fluids?

Standard in size I guess is what I meant to say, they are Buna, made for hydraulic applications.

Henry, you would save a lot of time just getting the tubing insted of boring them. I would use 260/330 brass tubing and just a polished steel precision ground rod. I think I went with the 260 brass on my cylinder (been laying there a couple years, can't remember).

[pugs]

I would use brass or plain steel tubing for the cylinders and just hone out smooth (oil will coat inside and paint outside for rust proofing) For the Rod I would look at precision ground stainless, should be plenty smooth enough (most anyway, some ground stainless rods aren't the best and would need polishing) and the stainless would keep rust away. Much cheaper and easier than zinc and chrome plating for what it is.

Joe's right Clyde , trust me I've been there and lost some hair . I got some seemless ss tube and rod . I was going to tread both ends of the tube and make brass ends but I like joe's glad end set up :)

IHSteve

[tracksntreadslou]

Another option is to check the local auto wreckers for hatchback cyclinders...Rod diamater is fairly close to scale size and if your careful you may be able to salvage seals ..might be worth a try

[JAMMER]

Henry don't get the inside of the cylinder to smooth you have to have some roughness so the oil will hold on, a polished surface is not good I am using brake cylinder hones on my cylinders and some I got from a place in Florida that they use on automatic transmissions to clean up bores. Ed

[sparkycuda]

Joe, awesome job, as usual. Do you have a reference for sizing the o-ring grooves? O-rings are easy to find, but I'm not sure how much clearance or squish to allow for proper sealing without excessive sliding resistance. Did you solder the large end on to the barrel or turn it from one piece of thick-wall tube? Thanks!

Ken

[dirtpusher9]

Hey Ken, The o-rings are already sized, by that I mean that if you needed an o-ring for a 5/16'' shaft, it is made with the right tolerances that it needs to do the job. When I cut an o-ring grove I use the same tolerances.

The end cap and the large end are soldered, yes.

When do we get to see what you are building, Ken? It's been a long time.

[tc1cat]

Joe, I think what Ken wants to know is- if you use an O ring for a .5" diameter cylinder, what diameter groove do you put in the piston? Do you just measure the O ring thickness and make the groove that dimension smaller than the cylinder? Or is there some sort of chart or rule of thumb that you go by when making the piston grooves?

Lynn

[dirtpusher9]

I don't have a chart, just made the piston groove a thousands bigger than the o-ring. You don't want it to tight and stretched or it will change the OD of the o-ring. Here's a link to what I referenced too. http://www.allorings.com/gland_dynamic_reciprocating.htm

[pugs]

Do you have a reference for sizing the o-ring grooves? O-rings are easy to find, but I'm not sure how much clearance or squish to allow for proper sealing without excessive sliding resistance.

Machinerys handbook has all that info in, strongly suggest anyone that tinkers with machining get a copy, lots and lots of good info.

O-ring groove sizes are in my 25th edition on page 2400.

[sparkycuda]

Thanks Joe and everyone for the response and advice about the orings. My Komatsu dozer is a very slow build. Been traveling a lot for work - last time I even took my mini-lathe and turned out four bottom rollers during the evenings at the hotel. I finally figured out the drivetrain and got gears, bearings and motors. Have modified cordless drill planetaries for the final drive and sourced pinion and bullgears along with bearings. Got a mini-mill about a month ago and have practiced using it - much more accurate and easy to use than the Dremel-in-a-drill-stand I "machined" the pivot shaft covers with. I will be building the tracks completely, which will take time, but have found only one product that is close to correct pitch (20.4 mm) for my dozer, but would cost about $500 just for the links and pads - too much for my wallet. Have taken pictures - just reluctant to post yet, since it will be a while before it looks like anything. I am always amazed how quickly some of you build things - to me it's astonishing fast! Machining is a skill I'm aquiring slowly - have to double check everything I do, which slows completion times. But I'm getting better at it. Seeing the work that people on this forum do, keeps me motivated.

Sorry for the lengthy posting...

Ken

[td9clyde]

I think we need more video's of those awsome machines at work lol i can set and watch them all day as i have before :)

[dirtpusher9]

I'd like to oblige you, but I burned up my hydraulic motor yesterday doing a little test and tune on the radio, so waiting a motor. The motor kept getting oil in it since I bought it and it would burn it out as soon as I fired it up. I brought a whole new meaning to the phrase (fire it up), yesterday.

[td9clyde]

AWwWwW that is bad does that mean you have to get a new hydralic pump?

[dirtpusher9]

No, pump is fine, just the motor. $27 Thank you Lord.

I might could Lou, but I won't. I beleive I'll leave the stunt blading to someone else. I have had them in some pretty wicked binds before. Brought down a 1.9 to 1 slope one time, riding the slope not with the blade run out to the side. But I was carring a nice big windrow to hold me up there.:cool:

Hey Joe are you holding out on us or just taking a break...Do you have your next build all researched and is it going to be !/14 scale?
Hey you know that we are running out of good quality reading material ..lol

Still not sure on the next build but it will probobly be 1/10 scale.

Been working on another cylinder design lately and looking for a job.

[9W Monighan]

I thought you had a job prospect.

[dirtpusher9]

I thought you had a job prospect.

I do, I have several but they are tied up in red ink and won't start till after the 1st. of the year. I ready now, so I just keep finding more prospects.

[ihbuilder]

Know what you mean . I got some , Spring work if I survive the winter

[tracksntreadslou]

Hey joe sorry to hear about the winter being slow ..Hopefully things pickup...Its feast or famin with constuction work these days...Before you know it they will be askin you to put in overtime...Good luck

[dirtpusher9]

Yeah, the jobs I'm looking at will be 60 to 70 hrs a week, fun, fun.

[JAMMER]

Ya Joe like they use to tell me it's a job of course they don't have to go there. Ed

[dirtpusher9]

EMPLOYED again, now I wont be a bum anymore. Whoo,hoooooooooo!!!!!!!!!!!

[ihbuilder]

thats great , Joe , funny , I just got a call last night for some work from 1 of my customers . now the lil kitties can earn their keep :)

[dirtpusher9]

That's good Steve, maybe it will be a good Christmas for all.

[ihbuilder]

I'm really hopping things turn around after the 1st , we got some potential on lot residential septic systems for the spring . this down turn could've waited 2 years for me then I'd be in a better situation . oh well gota deal with the cards dealt to us :(

[JAMMER]

Hey Joe and Steve I am very happy for both of you on the jobs that great news now you can gripe about not having enough time to work on models. Ed:rolleyes::rolleyes::rolleyes:

[elliot330]

Hi Joe,

Nice...

Love watching it on YT the power of it seems amazing... would love to see more information on the build? Did you ever detail the build of the D9 any where?

Thanks
Elliot

[dirtpusher9]

Thanks Elliot. I had most of the build on a site that went belly up and lost every bit of it but would give you any info that you would like.

[elliot330]

Thanks Elliot. I had most of the build on a site that went belly up and lost every bit of it but would give you any info that you would like.

I assume that was the "garden" forum. That's a shame. Its not really important, just it looked such a nice powerful scratch built model that I fancied having a read...

Having just ordered my dumper I should have my hands full for a little bit, but will be in contact if I need any other info... thanks.

Hi Joe, any news about your models, still own by you? Did it settled with the new work. It´s was a pitty when all info from the old forum got lost, so much info that can be useful for everyone starting up a new project.

I still have dozer and scraper no big rush to sell it but it is for sell, don't ever play with it anyway. I need to start another project.

I wasn't very happy with the way that the garden shut down but there wasn't anything I could do about it.

[td9clyde]

we could shure use some new video's or pics.......................i did get to run my dozer with a radio finnally lol Travis let use his batteries and wired up both sabertooth speed controlers it was cool to see it run on it's own , now we just need to get together sometime and show these fellas we can move dirt lol

[dirtpusher9]

Thats cool you ran it so where is the vid, Henry????

Been thinking about another video. But have to wait for better weather.

[edwalsh18]

hey i saw your dozer on youtube a while back and wow... i, like everyone else, didn't know it wasn't the real thing at first. really awesome! i decided to post up here after not finding what i was looking for.

i am interested in doing a D11 - 1/16th scale, i want to power it using craftsman drills. would you be able to show me how you mounted yours? did you keep the 2 speed trans (if they had them)? did you use esc or the PWM's? did u remove the gear reduction that connects the tranny to the chuck? what drill did you use? how did you mount to hub? i am anxious to finish planning this build and start building. i highly doubt mine will come close to yours but as long as it functions. i need to put it to work in my yard. any info u have will be appreciated. Thanks!

[td9clyde]

I ran it the video is on my youtube channel and on like page 16 or 17 or 18 in my thread lol

Thanks for the kind words.

I hope you do build the 11. Here is the best pick I have of the motors and how I mounted them.
http://i539.photobucket.com/albums/ff355/dirtpusher9/motormounts001.jpg
I used the Craftsman 19.2 motors and planetarys. Had to cut off part of the planetary housing to mount them sideways. I did use the 2 speed trany, just haven't put the servo back in it, that shifts it. I used the Sabertooth 2x25, it only draws 6.34 amps after gearing down 4 to 1 of the factory gearing on the drill motors. I tact welded the hub on. Hope some of this helps. If you need anythimg ,just ask. Sorry for the late reply.

[Stewmeat95]

I saw your videos on youtube, a very good machine you have here. My father is a mechanic and just built and engine for a D9 a while ago.

[dirtpusher9]

Thank you Stewmeat, and welcome to the forum.

[dirtpusher9]

Rained out!!! WOOO HOOO!!!
It's been almost a year since I was able to do anything in the shop, that's entirely to long.
When I first built the dozer I put a winch on it and stripped the plastic gears in it pulling my riding lawn mower. I used a planetary and motor out of a cordless screwdriver and geared down some on top of that. I've been on the net trying to find some replacement gears and the only ones I found that would fit have been discontinued. So I need some suggestions on where to find some. In the first pic you can see they have a lot of wear on them. Trying not to have to redo the whole winch, so all the help you can give would be appreciated.

Steve most of the internal gears at Stock drive are out of stock and are too narrow for what Joe shows here. I tore a old air drill apart the other day and the gears in that may work here. I'll be using those gears for my planetary reductions on those RC4x4 axles I just bought.

[td9clyde]

Finally ,....the guy comes back and is workin on somethin in the shop glad to see you back on here and tinkerin

Your right Steve, they don't have anything.

Henry, some of us have to work long hours.lol Feels good to be back at it, even if it is for a short time.

Well I got tired of looking for the gears, so I'm in the process of building a planetary and putting a bigger motor on it. Now just gotta wait for more time in the shop.

I guess thats why I never get anything from them :confused: + I got a good place to scrounge at :rolleyes: sorry Joe :o Say what brand /size screw driver ? I'll look next time . they got a crap load of them Air, batt and corded . I fond my dozer motors there . They got 2 more that'll work for another build I got on the drawing board .

[dirtpusher9]

I have the planetary built and tested for my winch, so far so good. I'm ready to wire this thing up and I want to wire it to a proportional channel but I don't have an extra one. So my question is, can I put a ''Y'' servo lead and go to the same channel that my blade works off of and set it up as a different model on my radio where all I would have to do is switch model modes? Is that possible?

[fhhhstix]

Joe if you have an extra two pos switch you can use this battle switch to run two servos independently from one proportional channel. Just Y off the channel to two servos and run the signal wires through the battle switch to interrupt the signal to one or the other.

Link to switch (http://www.dimensionengineering.com/DoubleSwitch.htm)

Travis

[dirtpusher9]

I was going to go through an ESC and trying not to put any more stuff in there then I have to. All that wiring starts running together, for me anyway. That's a cool switch though.

[fhhhstix]

You can Y harness an esc off any function on the radio and set it up like I described above or you can use an existing esc and use the battle switch to switch between two motors. I used one of those switches in Doug and Travis's to use one esc to control the up and down motor and bed extend motor with one ESC. Just some thoughts.

yea i know that feelin 10 to 12 hours a day 7 days a week been workin alot since April this year

[dirtpusher9]

Well, was messing with the dozer today and the hydraulics quit working so i checked everything out and the belt or band the connects the motor to the pump broke. So where do I find this at (Germany)?

[Lil Giants]

I just sent a spare I had to PFB last week...:rolleyes:

Try these guys, as they distribute Leimbach products and are quick with replys & shipments. Order some extras as it seems to be becoming common (I'll take one). And get yourself some extra goodies while yer at it & start another project ya slacker!

[dirtpusher9]

Didn't find anything in there Joe. And yes I do need a project. Hi my name is Joe and I'm a slacker.lol

Its more than likely going to be impossible to find this band, I bet.

[Lil Giants]

Down at the very bottom is their contact email, send them a mail of what you need & they'll get it for you. ;)

info@ttm-funktionsmodellbau.de

[titandigs]

If you address your email to Sven he is the owner of the Store and if they don't have what you are looking for he will find it if it is available, I buy all of my German things through TTM.
Paul

[dirtpusher9]

Thinking about skipping the band and pressing 2 or 3 pins in the motor side and coinciding holes on the pump side. This would eliminate the band forever and I wouldn't have to wait a couple months on the parts and having to pay that ridiculous exchange rate.

[doodlebug]

Try an outfit like this one http://onlinecatalog.tpa-us.com/viewitems/rcs-rcl-precision-flexible-beam-shaft-couplings/cl-micro-reli-a-flex-shaft-couplings-1-5-5-mm-bore
I just googled micromotor coupling.
Cheer's, Neil.

[Jared]

Joe, take a look here: https://sdp-si.com/eStore/
They've got belts up the wazoo and it's in the US. A quick glance at a few random belts says you'll be looking at around 5 bucks. I can't remember if they have a minimum order amount, though.

[dirtpusher9]

Thanks for the links guys. Neil, the way the motor and pump join together the coupling won't work. Jared, I'll check them out and see what they have.

[pigeonfarmboy]

Yeah I broke mine as well. I have the one from Joe coming as well as a few from Ric @ PMD. If you don't have one by the time I receive an extra I'll make sure to get you one asap! I looked around my local hardware store for some kind of metal band to surround the belt but didn't see anything. I suppose it's probably a good idea to have this "fuse" in place should something go very wrong in the system.

Thanks for the offer but it is fixed. I put 2 pins in it. If something comes unwound in there as fast as it spining it will be a mess anyway.

Got the winch working but need a bigger esc. The 10 amp wants to error out to easy.
