PFB's Vario JD 850D

[pigeonfarmboy]

Received the excavator finally and shot some video of it's first time out.

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

I plan to make another video showing the details of the model and also the radio setup I'm using.

[Azonic]

Congratulations! You have a very nice model, great video as well, you got the new trackdrive and thats good, the old one sucked!

Looking forward to see more of it, post up some pics! :)

[modelman]

This model looks huge:eek:. And the breakout force is impressive!

[doodlebug]

"Fra-Gile":D:eek: Thank's for the chuckle! Glad it finaly came.
Cheer's, Neil.

[Claus]

Need to post some photos of it in the "Show Us, Tracked Vehicles" section.

[pigeonfarmboy]

I'll try to get some good photos tomorrow. Been sick last couple days.

[Espeefan]

A great looking model! Good video footage too, but I'd also like to see some more photos. These are impressive machines.

[Lil Giants]

It looks like you've operated one of these before, pretty smooth, not much track bounce. :cool:

I'm using a Servonaut S20 speed control on the swing. What's nifty about how it works is that it somewhat ramps up the speed & down again so the start/stops aren't so sharp, I'm not shocking the geartrain. It'll help to reduce gear wear to keep your tolerances tight. It's alot of mass that you're swinging, especially if you're not level & stop abruptly on a downward arc.

Depending on the radio you're using, you could probably program your expotential for smoother start/stops too.

[pigeonfarmboy]

I believe this is the first time I've operated an excavator. The big issue I had was how much I was pushing down with the boom as seen in the video. Getting used to the controls too, once I have those down it will be smooth sailing. I can't remember the esc on the swing. I think it's a Schulze unit. It does ramp up and down but will stop abruptly if you stop the sticks too fast. A good point about gear wear. I will program in some curve to slow her down some.

What are your thoughts on the plastic track links Joe? I assumed they were metal and was a little disappointed when I received the model. I've pulled them off a couple times going over some rough terrain (way above what it should be operated on)

[Azonic]

I had the same feelings as you about the tracks, i also thought they were metal ones, but i had no issues with them breaking or some serious wear and i run on very hard garvel ground with lots of small rocks and i see minimal wear so far.

I actually asked a CNC guy over on a swedish board how much he wanted to make aluminium track plates for me, he said around $1200 for the compleate bits, if make them in stainless steel he said "double that price"! :)

Are you, Joe intrested in getting some metaltracks maybe i could talk to him again and see if hes up for the task?

Its alot of money but the coolness factor would go way up! :)

[pigeonfarmboy]

Stainless would be awesome. I'm about to start taking some machining classes so I'm going to see if I can't do something about it myself ;)

[Lil Giants]

Previously, my tracks only made a few revolutions before smoking a Sabertooth 2x12, then when I got a 2x25 smoked one of the motors. So my tracks have virtually zero wear to date! lol

And being that my tracks have turned very little, I was surprise to see some of the friction fit wrist pins have moved 2-4mm or so one way or the other. :confused: I wonder if I dribble a bit of blue locktite around each pin if that'll keep them from moving?

Kalle, when you say $1200, is that USD? Aluminum would never last under the weight of this model, too soft. And $2400 for SS is nearly half the price of the entire model!!! :eek:

I'll be doing lots of twisting & turning carving down the remaining part of the south wall, that'll be a good test for the durability of the tracks. ;)


If you find you're skipping a track often PFB, then you may need to tighten them up. Tap out a wrist pin to seperate a track, the idler just pulls out. Using a 7mm deep socket, screw out the locknut till you have about 2mm thread showing with your spring in place. That's where I set mine to just now, there's still a wee bit of give there yet, but hopefully not enough to let a track slip off the idler.

Yes that is usd, thats about how much it would cost to get them done, i also thought that alu. would be to soft but wouldnt the alu be harder then the plastic ones?

He also suggested ductile iron as a cheaper alternative but he said it easly rusts and probably wont last long, powdercoat?

Yes for stainless it would double the machining time and so the cost, so its not worth it as long as i wont win on the lottery! :)

[pigeonfarmboy]

I haven't had it apart yet, glad to see the tension can be adjusted. It's just set way too loose now.

[Azonic]

I haven't had it apart yet, glad to see the tension can be adjusted. It's just set way too loose now.

I have even changed the springs to stiffer ones, works much better now, have only lost my tracks once since i changed and that was when my friend tryed it for a while.

Hey PFB
I know i'm late,but congrats on your purchase of the JD excavator,enjoyed the vid,hope to see some more soon.Very nice model
Have fun:D
Tommy

[crawler07]

these are amazing machines for sure. The ground you were working with in the video seemed to be pretty rough and it didnt seem to have a bit of trouble breaking ground..I wish I had the money to buy one of these,but I just couldnt imagine the look on my wifes face If I told her I was going to spend 5,000.00 on a RC.....

[pigeonfarmboy]

Try doubling that figure and see what her face looks like. Euro conversion to dollar is uber-sad now.

[pigeonfarmboy]

Speedy Delivery!

Now to copy this one and make tabs for the axles. Still gotta figure out what tires to use. Thinking RC3WD ZXLs.

For those that don't know what this is... http://www.youtube.com/watch?feature=player_embedded&v=j1xnR2E-iJ0

[Lil Giants]

I forgot all about this idea.. as much trouble as I am having with the track drives & getting it around, I gotta make myself set too!

Looking forward to seeing how your's turn out. ;)

[doodlebug]

Way to go Nathan, I'd forgotten all about them.

Cheer's, Neil.

[Madda]

Oh that's great machine! Put some more videos now, I could watch these for hours. These builds here make me want to build one for myself altough I got to finish my last build.

How wide are these tracks?

[pigeonfarmboy]

2.5" wide

[pigeonfarmboy]

Both cradles welded up. Just waiting on wheels/tires now. Believe this will be my first project to make use of the lathe!

[pigeonfarmboy]

Braved the heat last night/this morning to some work on the dollies.

After some brain-storming with Izzy and Trav I used the RCP Crawlers TLT Straight Axle Adapters and cut off the ears. Cut down they offer the perfect spacing for the tire/wheel from the side plate of the dolly.
http://farm8.staticflickr.com/7130/7481085906_9d9f4bae73_z.jpg

Cut up a washer for work holding and space for the drill
http://farm8.staticflickr.com/7253/7481091060_a5ac4e3223_c.jpg

Had to turn the taper for the inside of the washer. (Zinc machines like sh*t) Here it is all mounted up to the dolly. A TLT axle fits inside and I'm using the tamiya brass bushings.
http://farm9.staticflickr.com/8150/7481099066_ea4a84fba1_c.jpg

The 2.2 ZXLs I ordered are way too big. Might go with the 1.9s. (the 2.2s are just going to have to be used on a future build..... ;) )
http://farm9.staticflickr.com/8026/7481094064_03d7b1f2fb_c.jpg

Spacing. I may take a bit more off the TLT adapter so it sits closer to the plate.
http://farm9.staticflickr.com/8019/7481096300_0283ff4a4d_c.jpg

This has been a good project to learn the ways around my new Taig machines. That machining class definitely helped me troubleshoot obstacles in clamping and indicating parts for better precision. I've never used a rotary table or 4-jaw chuck before. It's time consuming to setup, but it's a great sense of accomplishment for me knowing how to quickly and easily set them up now. Time to let my ideas and drawings become real objects! Very excited.

[fhhhstix]

Good job Nate.

Travis

[dabears]

Looks good Nate!

[Lil Giants]

I could use a seet of them too, if you're game to make another? :D

Looking good so far. :cool:

Are the tires solid rubber? Or are you packing them solid?

[pigeonfarmboy]

Not sure on the tires, hopefully they'll hold some weight stock. Otherwise I'll stuff more foam or plastic bbs in them.

I can make you a set, it'll be after Indy though.

[pigeonfarmboy]

Went with studs into the plate (When a full-scale CAT engineer says so, you do it :D )
http://farm8.staticflickr.com/7255/7552681524_dee3c5c082_c.jpg

http://farm9.staticflickr.com/8426/7552684700_7108d07a97_c.jpg

Fast forward they are just about done. Just waiting on one TG10 axle to arrive to finish the second. Cables are installed and I ended up having to stuff the tires with really dense strips of foam until full.

[woodhog]

If you made those wheels i need a set for my 544j ive been working on converting:D

[woodhog]

also you have a lot of shavings next to those nice bikes:eek:

[pigeonfarmboy]

If you made those wheels i need a set for my 544j ive been working on converting:D

Nope, those are RC4WD they make them in 2.2 and 1.9

Whole garage is dirty. The bikes don't have a chance at keeping clean between sparks flying from the rally car or rc builds.

[fhhhstix]

The track dollies look good, your a mad man Nate.

Travis

[Izzy]

Awesome work PFB - they are looking great!

[pigeonfarmboy]

Great success! Just a few tweaks and these are good to go!

http://www.youtube.com/watch?v=p84DrfttK4g

[Grainfarmer]

Looks great!

[RCTech9]

Good job PFB! Now you need to build a truck to use to move it with.

[doodlebug]

A little bit of Aerosmith & Walk this way!
Look's great, nice job

Cheer's, Neil.

[Snochaser]

Nice exacution Nate. Well done.

[Madda]

You did great job! Now make a video of that digger behind a truck see we could see them more in action!

Btw, that video was running on background for awhile and that sound was amazing, just like a real digger!

That's freagin sweet the video is cool to now all u need is his off road
dump truck

[pigeonfarmboy]

Gonna tackle that build soon. Thinking 769D

[TRUCKMAKER]

Nice job on this set up Nate! Is the fifth wheel bucket mount a scale 1:1 prototype?;):D:D

[Brian in PA]

Very cool Nathan! I have never seen this set up before watching the video. A very innovative idea.

[Lil Giants]

A tamiya rig will certainly pull 80lbs, but to try to carry 80lbs too :confused:? You'll want to replace that plastic 5th slider plater with a metal one. ;)

[Tamiya Cowboy]

A tamiya rig will certainly pull 80lbs, but to try to carry 80lbs too :confused:? You'll want to replace that plastic 5th slider plater with a metal one. ;)

We hauled Dirt Pushers dozer around at indy with them plastic parts and did not break anything and it weights in at 110 I think Joe said..

[dabears]

Now thats cool Nate!!! Love the idea behind it. Great way to move it around a site without the time of loading it on a lowboy!! Great work!!

He'll be fine for a once in awhile pull around but for a every day use you might want to beef up the 5th wheel plate . With Nate's set up he only has statically 40 # on the truck . It's the dynamic loading you need to worry about whereas , I highly doubt you will be pulling it around on uneven ground/roads at a high rate of speed ;) Joe's D10 pulls real well on wheels but try to drag it hitched to the 5th wheel (not that we would :eek:) looks good Nate , now I wana see a vid :D

[pigeonfarmboy]

Nice job on this set up Nate! Is the fifth wheel bucket mount a scale 1:1 prototype?;):D:D

No I'm going to trademark it ;)

Going out of town for work, will have to get video later.

[Lil Giants]

Joe's D9 is about 80lbs.

Nate, it'd be interesting to know what amount weight would it be at the bucket with the rear of the tracks resting on the dollies, could you weigh it on a bathroom scale?

What do you think of a tri axle jeep to spread the load? Your trk with Russisloud's simulated air ride suspension, a load such as this would certainly test its limits! :D

[pigeonfarmboy]

Got no scale, that way I can't check how fat I am...

I did test the rig tonight and it pulled the vario just fine. Just need to load the front of the truck with weight so it will respond to steering better.

[Lil Giants]

Did you lubricate your 5th wheel at all?

A spray on graphite is relatively clean to work with, dries very quickly.

[pigeonfarmboy]

Nope, probably not a bad idea.

[Izzy]

Looking good Nate- this is really kool!

[doodlebug]

Hey Nate, do you have a farm store near by, with scale's?
Post office scale's, not practical option.

Cheer's, Neil.

[pigeonfarmboy]

Finally warm enough to get some welding done on these buckets Joe traded to me for my 1st dollies. (V2 will be built soon) Although rare, sometimes it's nice to have a small TIG for this tiny stuff!
Not bad for a couple hours tonight! Should have them finished up this weekend.

Is that your 1st time using the tig?

Good to see you're getting back at 'er. :cool:

[pigeonfarmboy]

Good to see you're getting back at 'er. :cool:

Not saying my welds are amazing but if someone can edge weld this thin sheet metal on their first try, they need to quit their day job immediately :eek:

[dabears]

Buckets are looking great!

[pigeonfarmboy]

Time to improve the beast!
- Finish buckets
- Take out the worm gear swing drive and replace with Joe's option
- Redo the cab interior. Was sent to me as the 1:12.......blah
- Counterweight is going to get quick disconnect (gets in the way when lifting the model)
- Rewire and possibly add SMX and speaker enclosure.
- Stop stick pin from working it's way out during operation.
- Weathering to make it look more "accurate"

[pigeonfarmboy]

Stripping all parts off (Hope to get the cylinders painted too)
http://farm9.staticflickr.com/8246/8666641151_6af25ab655_b.jpg

Had to make an adapter for the new swing driveshaft. Pretty satisfying making my own parts!
http://farm9.staticflickr.com/8265/8667746598_d8e8c4061e_b.jpg

[Espeefan]

Weathering? :p The more you use it, more used it will look! Go all natural.

[pigeonfarmboy]

Weathering? :p The more you use it, more used it will look! Go all natural.

Bah, no offense to Joe, but even his doesn't look the full-scale part when it's uncleaned. It certainly helps, but I'd like to get really detailed with the weathering.

[cdm]

fake weathering belongs to plastic models in dioramas.

leave it be!

[RCLogger]

Great job on the new buckets. Go wild with the weathering, the more time you spend adding detail to them the better they look. Keep up the good work.

Greg

[pigeonfarmboy]

fake weathering belongs to plastic models in dioramas.

leave it be!

I disagree. I could cake this thing in dirt, never clean it, and it still won't look like a full-scale machine. The body is made of fiberglass, that won't rust. Even if you "leave it be" you gotta transport it somehow. Fingerprints don't look so hot on a scale model.

[dabears]

I say some nicely done (not overkill) detailing would look very nice Nate! Go for it!

[Izzy]

Dang Nate - di d you get drunk one night - your finger tips are dirty????? Waht's up with dat?????

It is nice making nice parts your self aint it? I am realy getting close to making a serious effort towards a mill....

[doodlebug]

Sunshine will weather anything! None of my 1:1 toys are shed queens!
Cheers, Neil.

[YoungGunz]

Looking forward to this one, Nathan! I think this could look spot on when you're done with it :D

[pigeonfarmboy]

I'm tired of the model looking like it's made of plastic instead of metal. Just look how shiny that boom arm is! I guess that's the idea behind my weathering. If you wanna call it fake or modeling, I suppose that's in the eye of the beholder.

[Izzy]

doodlebug - so you leave your stuff outside? I'd be divorced before night fall the next day if I did that????? I don't dsut em off but I must agree with Nate - they just don't look like the 1:1 units. I don't do it on my units cause I don't have the skill set to pull it off......



Izzy

[doodlebug]

Yah, no building for the 10 wheeler or the yellow iron, suck's, but that's life!
But then the panel's on my Cat 305CCR don't even fade evenly, kinda odd to me? Look at Cat backhoe cab's and how the plastic roof fade's to white.
What few RC toy's that I have, well they're dust queen's for now, and inside.
Cheer's, Neil.

Got the stick pin all finished up. Not wild about the look of the socketcap but it'll do for now. Special thanks to Lynn (tc1cat) for all the tips he's given me to help me along in my machining endeavors.

[fhhhstix]

The new pin looks good Nate, nice job.

Travis

[ihbuilder]

TIG result is quite promising. Mine is just arc welding, it is very hard to control arc. Are you using Agron or Co2? Does it worth the effort to upgrade to TIG?

heck yea :D

[tc1cat]

All of your upgrades look nice. You might try a button head capscrew instead of the regular allen head capscrew. They are much shorter in height and should blend in better or find a brass screw.

[Rvjimd]

Nate,

Can you counterbore a hole in the brass part so the socket head sits down a bit? I assume that is the look you are not quite satisfied with?

Looks like a fun project!

Jim

[pigeonfarmboy]

TIG result is quite promising. Mine is just arc welding, it is very hard to control arc. Are you using Agron or Co2? Does it worth the effort to upgrade to TIG?

Definitely. Much easier to control the heat to the workpiece.


I already fixed the screw side but thanks for the suggestions gents!

[JAMMER]

I have a question if you are into such a detailed model why didn't you use the same lock foe the pins that the real excavators use? Ed

[tc1cat]

Much better!! Sometimes you just have to set back and think about things:D

[pigeonfarmboy]

I have a question if you are into such a detailed model why didn't you use the same lock foe the pins that the real excavators use? Ed

Show me a good reference photo and I'd be glad to. Here in cornland, there's not a need for such large equipment. Suppose I could go up to Moline and take some photos (if they even have them there)

[pigeonfarmboy]

Moving right along. Edge welding is easy to screw up, looks like I've got the machine setup correct!

http://farm8.staticflickr.com/7437/8722651226_a1a682932a_c.jpg

[JAMMER]

To answer you about a picture I did not get one but I called the local Deere equipment dealer and they said that there is just a strap over the end of the pin with a bolt holding the strap on. Ed

[ihbuilder]

like this Nate ,

[rockNmayhem]

Nate your welding on that bucket looks great. It takes lots of practice and usually many years to achieve the quality of weld you have there. Will definitely be waiting for the next pics of that bucket.

Tyler

[pigeonfarmboy]

Started on V2 of the dolly system today:

Nope, not a 4cyl. model engine ;)
http://farm3.staticflickr.com/2842/9052874085_c70f52f72e_c.jpg

Just like the last version, I'm modifying an RCP Crawlers TLT Straight Axle adapter so I can service the outer section easily. This time it will mount cleaner to the frame via screws.
http://farm6.staticflickr.com/5518/9052961459_bcc08f0e27_c.jpg

The axle housing will mount to the plate with counter-sunk screws and then the plate will bolt to the frame. Probably hex heads to make it look 1:1.

Bolted up to the wheel
http://farm6.staticflickr.com/5540/9055123158_bbe54892d7_c.jpg

Went with 2.2s this time. After looking at the video closer, the 1.9s were too small.
http://farm4.staticflickr.com/3715/9055115184_b32eb504a1_c.jpg

Who needs a laser/water jet? Bandsaw, grinder, and file son! (Except for that whole need to make 3 more part :( )
http://farm3.staticflickr.com/2851/9055117852_4bb2850004_c.jpg

[Kingcam2]

looking good Nate.

[Espeefan]

Nice machining! Is the frame of the dolly CNC machined or cut with a bandsaw and polished on the edges? What kind of mill do you have?

[pigeonfarmboy]

Nice machining! Is the frame of the dolly CNC machined or cut with a bandsaw and polished on the edges? What kind of mill do you have?

First piece pictured is bandsaw/grinder/belt sander/filed. I cheated on the next three and used the plasma torch. All of them are cut and finished. Just need to weld standoffs in place to get the 2.5" spacing. Going to figure out a different method for tire support this time. I like RCP's idea with his Kenworth tire inserts. Wrapping around like I did last time definitely made a small bump in the tire.

[pigeonfarmboy]

New swing motor/gearbox installed and body cover done.
http://farm4.staticflickr.com/3821/9456512862_c0b38f3aa7_c.jpg

[pigeonfarmboy]

Got the new dollies finished up. I lost track of how much time I have in these. Well over 20-30 hours. The first versions I didn't spend as much time in the preplanning as I did on these. The fit on this pair are **** near perfect and look much better on the excavator with the 2.2 wheels/tires. (Sorry I didn't get more photos of the build process. I'm in Indy rush mode to get everything done before the show)

Milled slots in the bottom of the uprights and dropped in and tig welded the rods in place. Used some plates to keep the uprights spaced correctly while in the vise.
http://farm8.staticflickr.com/7284/9540695001_d3a08e1425_b.jpg

Next was cutting new inserts for the tires to support the weight of the 850D. This dense foam stacked inside the tire should do the trick. That's a special tool made by Olfa for cutting out lexan body wheel wells.
http://farm3.staticflickr.com/2812/9543490618_834882e8e0_b.jpg

All the foam cutout it's time to assemble the beadlocks.
http://farm8.staticflickr.com/7366/9543487344_21f79e1e28_b.jpg

All assembled and painted up. Wheels will be painted black or grey another time.
http://farm8.staticflickr.com/7351/9541863159_9e435e00ec_b.jpg

Also got the new buckets welded up and ready for paint tomorrow.
http://farm8.staticflickr.com/7373/9521612742_4bf048bb43_b.jpg

[Espeefan]

Wow, those buckets and the dollies turned out beautiful. I'm not a professional welder, but your welds look really good. Nice work.

[apfubar]

The buckets look great...

On the mounts, are they just tacked on? ... Sorry the engineer in me just had to comment. :-)

[pigeonfarmboy]

Yup just tacked. I ran out of tig gas so after the photo I went over to the mig to finish it up.

[pigeonfarmboy]

Can you see the tungsten contamination spots? I sure as ____ can! :eek:

http://farm6.staticflickr.com/5475/9552963690_6467396cce_b.jpg

Got some inserts made on the lathe too. Still gotta make the other 4.
http://farm8.staticflickr.com/7381/9550170993_906768af0c_b.jpg

[pigeonfarmboy]

Dolly system didn't work. Back to the drawing board. Need to get more weight further back or get the top bar to lock into the cradle better. Front section was dragging on the ground. The tire inserts held the weight just fine though. I suppose this is what happens when you guess on the geometry haha!

On the other hand, the big bucket was awesome for Indy rubber!

[Lil Giants]

The mig welding I've done on my buckets don't look that bad now, eh Nate? :p

I ran out of tig gas before I got to the mounts so that's all mig in there. I can always grind them down I suppose.

Finally was able to get my stuff out of storage from the fire and tear into this thing. Body was heavily damaged but I've got the new raw body from JDH ready for paint.

Haven't tested the electronics yet but there's no visual damage. Looks like all I'll have to replace is the hydraulic lines from the splitter to the arm cylinders. Those were melted in spots so I'm sure the fluid was cooked pretty good. Anyone know a source on this side of the pond for those lines? I believe they're the 6mm lines but I forgot to measure last night.

I think yesterday was Farris Bueller's day off.....

Gardentrucking.com sells 1.5 mm and 2.5 mm hydraulic tubing for about $2 a foot and RC4WD sells 2.0 mm tubing about 40" long for $17 but I didn't see any 6mm anywhere.

For reference:
Smaller hydraulic line for the boom/stick/bucket cylinders uses the following:
Parker PA 12-PHL DIN 74324
Size is 4mm OD x 2.7mm ID x 0.65mm Thickness

Can't seem to find any retailers state-side that carry the Parker. I found this stuff on Mcmaster Carr today and will report back if it works well:

OHH!!! I can help! I am about to order this

http://www.grainger.com/product/PARKER-Tubing-2VKR2?s_pp=false

for my LR 634, it's close enough to 3mm OD.

You might find your size on there. Good luck!

That tubing works great and is the same stiffness as what the excavator was supplied with.
