Having seen your previous work, I know that when it's all did & done, it'll be well crafted, & look amazing.

Thanks skeeter, and yes!! Have the perfect project for many years to come. Once I get the time I'm going to make an indoor screening plant. Large scale!! Well still scale to our equipment but want to move a lot of material. I have a lot of dirt that has been dumped for fill from rock raking /seeding yards. Perfect to haul into barn and then use the scale equipment to process. And best part I'll gain that wasted soil back. Might take a couple weeks to process a couple yards and then just a couple scoops with 1:1 equipment . But it is an endless supply with a purpose. !!

That'll be great to see you fab that up Cooper... you build a Vario sized excavator & a couple cubes could be done in an afternoon.

Update,, still have some minor things to change but gettin the gist of it.




The drive shafts are long, they will be cut to size later





And I left enough material in relation to rims and hub to be removed if tires shrink more than anticipated from the mold process. That's kind of difficult to calculate precisely. (At least for my redneck engineering) ����

Oh and bearings will be farther onshaft for a retainer to keep them. I just don't want to pres them in yet. And I'm going to eliminate the chamfer between the two axle parts , I don't want that gap. Like I said still working on some fits and tweaks

About how much machining time do you have in 1 axle? Your machining is outstanding!!

That is a hard question to answer, many parts,,, with wheels, probably around 12-13 hours? But I'm still learning and playing with numbers. Like the axle extension part that I.d. Of bearings slip over I had 1.5 hours in machine time. But now getting specs on insert and cutter I can probably drop that down to 45min. And another tool path I was using cutting speeds same as rapids and that took a 1hour program down to 30min. But I'm not breaking or pushing things. Lots to learn for a simple mind like me. And lots to improve speed up on. But I'm not trying to speed things up as in a production environment but just hate to see slow movements when tools are not engaged in a cut. . And after the initial program was proven to do what intended. The bearing pockets were a few trial/error and sneaking up on proper clearences to get them a snug hand press fit. Wasn't using a boar tool just path and the tollarances on machine are pretty good. I'd say I get a good 80% score mark all way around bearing pockets. Good enough for me .

Been a while so some data dump,,,

The back axle trunnions,











Steve (Ihbuilder) gave me the good idea of pressing on a piece of stainless for the bushing. Now the bushing material will slid against steel instead of aluminum. Thanks Steve. The back axle oscillates something like ?? 10 degrees.

Front axle/frame mount









I still have to drill holes in axle. Wasn’t sure about how everything was going together at time. Still have a bit of the redneck engineering, build parts first then figure out how to fit them together !!!

And now working on the frame that pivots along with mounts for turning rams





Building them to accept a tab and slot construction that will align and be welded together . On the 1:1 no hardware is visually in frame as they are cast and welded pieces. So I didn’t want any screws visually and welding is needed.



Still have to cut holes for the steering rams and bolt holes. These pieces required 6 different set-ups. Time consuming,,, as another said welcome to the machineing world

Wow There are several leagues in this hobby, and you are playing with the very best. Looking forward to more pictures.

The side extension supports[/QUOTE]

Me not being a machinist, how do you separate the milled supports from the base strip? Do they require another step to get to finished thickness?
