Re: Hauling Dirt out of my basement (present day)
 

Thx for the info Joe, seems to be a nice machine!

I only heard that it was hard to get parts and such lately from Stahl, not that he closeing, hope that someone takes over hes production, they seem to be very nice models.

Maybe i should keep an eye out for a used one! :)

Re: Hauling Dirt out of my basement (present day)
 

Frank said his WA 500-6 loader will be available middle next yr. ;)

Re: Hauling Dirt out of my basement (present day)
 

Yea, i just have to check the price on that one first! :)

Instead of wasting time and money getting a dual sprocket, I just added a washer to either side of the sprocket to fill the width of the track link. I just need to chuck it up in the lathe to true the diameter so it runs level. It's fitting quite snug as it is, I'll try it 1st, any binding & I'll have to trim the face on one side.

Re: Hauling Dirt out of my basement (present day)
 

very cool joe! way to use the welder!

Re: Hauling Dirt out of my basement (present day)
 

Way to go Joe, You're thinking outside the box! Thank's for sharing!

Cheer's, Neil.

Re: Hauling Dirt out of my basement (present day)
 

Finally Joe, its time for that 850 to move its feet! :)

Great solution for the sprocket, some black paint over that and you shouldnt see the washers, if you even care! :D

One thing i noticed when you screwing the bevelgear unit to the sideplate, you wont be able to mount it to the undercarrige.

Instead mount the plate first to the UC with the rollers and motors on the plate, then slide the bevelgear unit into the undercarrige, just slide it in, when it stops, turn the bevelgear so that the yokes lineup and attach to eachother then push the bevel unit full in and screw it to the undercarrige.

Its a very neat way how they did this, 4 screws and you can pull the bevel unit out, i have done it once out "on work" and its so easy.

Now you will finally get to use the model full out! :)

Re: Hauling Dirt out of my basement (present day)
 

Yeah, that took about a half second to realize Kalle when I set the outer plate to the u/c... this aint gonna work! :D

4 bolts??!!! Mine has 8 bolts to secure it in place. 4 on the outer plate & 4 on the bridge.

Amazing when I get JUICED to build, started about 8pm... now it's 7am... oops! :D It was about 2am when I had to make a trip to my farm shop 3miles away to re-tack the inner washer on one of the sprokets. I find it difficult to mig with 035 wire on low amps, need another mig for hobby use with 023. ;)

While I was there I welded a quik tach to my drill, the precut plates I got extras from Kalle when he sent me a duplicate of his ripper tooth last winter. :)

When it was time to take my u/c to the machinist, I strip it down in about 40 min... 9hrs to re-assemble :confused: got 'er done.

Time for a nap. :D

Re: Hauling Dirt out of my basement (present day)
 

Haha! Yea, i hate that feeling! :) When i figured it all made sense as it always does!

Ohh my bad, youre right, i forgot about the 4 ones on the outside plate, 8 on each side.

So the extra mounts finally came to use, looking forward to see the difference on the 850!

Re: Hauling Dirt out of my basement (present day)
 

The DX8 I'm using with this 850 has five proportional chs, two 3pos switches & one 2pos switch. So that leaves one proportional (dial) & one 3pos to try to operate this Sabertooth.

I have the turning on the 3pos & all I could get it to do was either off, turn right slowly or turn right quickly. Couldn't get it to turn left.

So I started monkeying with the mix, making aux3 (dial, for/rev) master & aux1 (3pos, turning) slave. Master has a bit more epa than slave, also factored in negative offset & F Mode 2 to turn mix on (0 or 1 is off) and now it works left/right! :) But only if I'm moving for/rev.

I just watched your DX10 vid PFB, I hope my thumbs are long enough to reach the sticks! :p I think the DX10 will be the ultimate for any constr rc. :cool:

Re: Hauling Dirt out of my basement (present day)
 

The 850 took a new route to the basement last night, a bit of a tight fit! thru the window. I was thinking afterward had I removed the bucket that might have given me another half inch lower & probably drove straight in... next time. Don't want to carry it down the stairs no more... and I can easily split it half to go up the stairs if its disabled.

Had a little accident last nite... thought I was done assembly & ready to go the basement when I noticed the swing motor seemed a bit loose. I had to separate the 850’s house from the u/c (again) and then balance the house on the tracks with wooden blocks to take the swing motor pinion off to get the motor out. It sat there for ten minutes while I sit there in front of it. Step away from the bench for 30secs & the house hits the floor! I heard it starting to slide and grabbed it by the stick, but not before it struck the stool 1st. My throat was hoarse from screaming profanities for two minutes. (it's funny now :D)

Minor damage to the ceramic coating on the boom & stick, took some paint off the counterweight and the DX8 rx no longer works. The light is out in the larger box where the leads plug in, but the light is on in the smaller box. Got no power to the servos nor esc’s. Good thing I have a spare on hand... shyt happens & I hate waiting for parts.

It’s quite the dent in my linoleum floor. :eek:

Gonna Have to mount an overhead crane in the workshop to work on this now heavier equip safely. :D

Re: Hauling Dirt out of my basement (present day)
 

This is the oil color after approx 30hrs of 26bar pressure, my camera doesn't really capture the right shade. It's dark, but I can still see through it somewhat. Atleast it's not black like the aluminum cyl barrels of Leimbach with 15bar press. ;)

Engine hoist!!

You won't want to hold the 10t in your hands. You will use the weird shoulder harness because it's ridiculously comfortable this way. Either that or if you put it on your lap while sitting it would work well.

Re: Hauling Dirt out of my basement (present day)
 

Are you using plow blade oil or Vario's stuff?

Re: Hauling Dirt out of my basement (present day)
 

I guess I will have to adapt however when I get it... I've always operated with just my thumbs though.

Esso Hydraul 50 (10W), get it at the local petroleum dealer.

Re: Hauling Dirt out of my basement (present day)
 

How do you have the DX8 set up to run the 850?

Reg

Re: Hauling Dirt out of my basement (present day)
 

boom^ swing> stick^ bucket>

Sabertooth with the differential mix on, dial switch (aux3 ch) for/rev, 3pos (aux1 ch) turning... although center of 3pos is not 0s? Is it 1s one direction & 2s the other direction? Don't know what the problem is that I can not get this 3pos to work the way I want or think it should. :confused: Centering 3pos turns right.

Fiddling with the mix, aux3 Master / aux1 Slave and adjusting a few other variables like offset & sub trim, I can make it turn left.

Moving forward, center aux1 turns it right. Moving forward, activate mix with F mode switch turns it left.

This is how I got it to work with the chs I had left to use. There's other electronic devices out there to expand small ch radios to double up functions on the sticks, but I want to be able to use the arm with the tracks to climb steep slopes.

Re: Hauling Dirt out of my basement (present day)
 

haha sounds complicated for sure. I have a DX8 as well and have been trying to formulate a plan for controlling my Volvo if I ever get it finished. I plan on running a hydraulic thumb on top of the other functions so I may have to run a second reciever for the track drives. I would like to have it all on one but I can't see it being possible without buying another radio which is not in the cards anytime soon.

Re: Hauling Dirt out of my basement (present day)
 

I wonder if you can take another Tx / Rx and turn the 2 sticks into foot peddles for the drive just like the real excavator . Or just extend the sticks like in our old koering 6605's . I'd be right at home with that set up ;) .

Re: Hauling Dirt out of my basement (present day)
 

This is what you need Joe !

This machine is a beast

Re: Hauling Dirt out of my basement (present day)
 

The problem I see with using two different rx's is the time delay to switch between each one, which is about 10-15secs (though I never really timed it, seems long).

From http://www.leimbach-modellbau.de/ Steuerkanal-Umschaltbaustein Part#1120F Price 103E

http://www.leimbach-modellbau.de/Images/img124.jpg

You plug six servo leads into rx, then you can run six channels on your radio on the yellow colored side, flip a 2pos switch (Gear ch on the DX8) and run another 6chs on the white colored side. All leads are numbered 1-6

I have one of these, works pretty good, I'll have to dig it out. I could likely put Y servo leads on the boom & stick to run them on both sides of the device to use boom stick with the tracks. I forgot I had this. :)

Steve, after seeing what JensR did to mutate two radios with gamer joysticks to operate his grader... anything's possible! We just need to employ the ppl with these special talents to make it for us. ;)

Yes, quite a beast Greg, I think the basement is too small for it though. :D

Joe , I had the chance to try Rod's (stepside) excavator , stationary . it's taking me some time to get use to it :confused: If I sat in a seat with the joysticks beside me and 2 foot peddle/levers I'd be at home . as far as making that setup , it'll be some time and $$$ for me . I'm still a little green on these electrics yet :o motors too . the driveline on the Mack has become a majore disappointment :( .

Re: Hauling Dirt out of my basement (present day)
 

I'll have to look into getting something like that for sure! It would be much better than switching models(rx) all the time just to move the excavator a few inches.

Thanks for posting that!

Re: Hauling Dirt out of my basement (present day)
 

Chiseling away at the wall with the ripper & bucket, making pretty good headway by finding some soft spots near the cement foundation vs outer part of the wall that is rock hard! I've got an idea in my head to make a rock saw!

The power of this brute just continues to awe me, the boulders that the ripper tooth will pull up from an inch or two below the surface.

Re: Hauling Dirt out of my basement (present day)
 

Thanks for the photo's Joe, how are the pins in the boom holding up ? Are they brass and is there a way for you to get some grease in them ?

greg

Re: Hauling Dirt out of my basement (present day)
 

The pins are steel, friction fitted in the lower boom pivot and upper & lower stick pivots with hard plastic bushings in the thinner connections. Not a bit! of wiggle in the arm anywhere, after 35+ hrs of hard digging! And the arm has been stressed alot with side loads/twisting by cutting hard ground with the outer 3rd of the bucket. ;)

Re: Hauling Dirt out of my basement (present day)
 

My latest try at a jackhammer failed yet again. :( Just can't get the right motor for the job, always too fast & too weak.

So I was thinking maybe a rock saw, this 850 is big enough, heavy enough to hang a large gh motor on the end of the stick. I got this here sprocket set from a 10spd bike, how do I get apart, each sprocket by itself?

Re: Hauling Dirt out of my basement (present day)
 

Joe , you got a liquid wrench (oxy/act. torch ) ? if so how good are you with it ? basically cut some slots on the ID bore and collapse it . Looks like you already started cutting , is it hardend ?

Re: Hauling Dirt out of my basement (present day)
 

I think that cassette is fittet with blind nuts or such, the other smaller sprockets was separate right? I think if you could use a hacksaw in between the sprockets to get them to separate, maybe?

Re: Hauling Dirt out of my basement (present day)
 

Dude you have the best toy collection (full stop), thats also a challenge to anyone else.
Normally the cassettes are bolted together but that one looks to be a pressfit; your headed in the right direction. Maybe a small (100mm) circular saw blade like on the cordless ones, run a bolt through with some nylocks/setscrews and washers and a coupling to the motor.

Re: Hauling Dirt out of my basement (present day)
 

Seeing as how the 850 can rip what your trying to dig, you might try a ripper bucket. I know full-sized these buckets will dig anything that can ripped. http://leattach.com/multiripperbucket.htm

Re: Hauling Dirt out of my basement (present day)
 

Cool, I didn't know anything like that existed! I got the quick detach for my 850 with the intention of making some different tools.

Re: Hauling Dirt out of my basement (present day)
 

So I chucked the cassette (is that what they're called :confused: ) in the lathe & it started sparking like grinder... harden steel, eh? So I worked it over a bit with a cutting disc in my dremel & could see the parting line that the sprocket was not formed with hub. Took it my farm shop where I have MORE POWER! :D & ground that shoulder off to get 3 sprockets off. The other two I'm not sure what's holding them, but they're too small anyway.

http://img.photobucket.com/albums/v1...2011/003-2.jpg

A small 4" saw blade is a great idea footprint, as it'll have offset teeth with carbide tips. :cool:

Come to think of it, hacking up a saw blade, one could probably duplicate the rock bucket you showed hvy 1ton. ;) Can you weld that kind of steel with a regular mig welder?

All the ripping I've been doing lately, I'm hitting stones constantly, so I've lost interest in the "rock saw" idea. :(

So I got to thinking that I should redesign my ripper tooth, give it more of a heel to work as a pry bar for when I strike rocks or really hard soil, curl the tooth to pry it up. Made it from 3/16's steel which is half the width of Kalle's tooth, gave it a sharp beveled edge and it's ripping like butter now! :D

I was thinking maybe making another tooth from 1/8 steel with more heel yet & maybe moreso like a "L" shape with 30degree rising angle, sorta like a subsoiler shank.

Re: Hauling Dirt out of my basement (present day)
 

You don't recognize farmer gobb it on welding Nathan?! :D I bet I'll never break it off? :p

I'm way out of practice, but I made it look prettier on this one. :)

Gotta hand it to Kalle's buddy who mig - tig welded this 1st tooth, deep even penetration, pretty near had to cut all the way through before it let go. :cool:

Re: Hauling Dirt out of my basement (present day)
 

Joe, I just had to tease you a little. :D We all have our 'off days'. I do pretty good with MIG welding. TIG welding is something you need to do often to be good at it, and stay good at it (not me). The other welds are looking much better. I joke with the guys at work, all the time. 'The bigger the blob, the better the job!' :D

Re: Hauling Dirt out of my basement (present day)
 

Hey Joe, this was at the LEA booth at ConExpo. Yes I have the business card from the builder, if you are interested.
Later, Neil.

Re: Hauling Dirt out of my basement (present day)
 

Wow thats a bad *** bucket! That should be the bucket for you Joe!

Any more info on he's products?

Re: Hauling Dirt out of my basement (present day)
 

Hey Joe,instead of beating your equiptment up diggin in the hard stuff.
what if you went to work & made a horizonal boring machine on tracks.Then get some 1/2"dia X4"long pvc pipe & two caps.
Glue the one cap on,fill the tube with some good ole-black powder.
Then drill a small hole in the other cap for the wick,glue the cap on,& stuff er down the hole. Leave acouple of inches of wick hanging out the hole.
Giver a light & stand back,then all's you need is a loader to load out the pile.
You could get really trick & use a car coil to set it off.;)
Now just think of the vid that would make.:eek::eek::eek:
Instead of y-tube,Baby! You'de make the Canadian national news!:cool::cool:
I'de be more than honored to give you a hand makin the boring machine.
Have been tossing this around for awhile,before I suggested it.
Didn't want to get laughed off of the forum.But the more I thought about it,the better of an idea it seemed to me.
I have most of the parts to build one,except for the under carrage & tracks. See'ins on how you have so many excavators,& acouple of them have a million hrs on them. PERFECT! There's the under carrage!
Just a suggestion.
FGD
Something like this.

There's some stuff called s-mite, same idea but it takes 24 hrs for the expansion to take place. Yah, anti climatic! It's a slurry that's mixed with water to make a slurry.
I will post the bucket builder tonight.
Later, Neil.
