Sorry about late response, only way I access the forum I s from my iPhone and it takes forever if at all to open pages.

Smallest end mill I’ve used so far was a 1/16 4flute. Ran good and still have it. Was cutting the details on cutting edge of bucket. Mild steel. I do take the time to adjust run out on small cutters.

As far as the deck pattern. I used a 1/8” 4flute 90 degree chamfer tool. I think I used a trace toolpath with -.025 stock to leave as a cam programming.

And if you are referring the the offset faces as the diamond pattern on the cab that was just a simple contour with stepover of .005 with a 3/16 ballmill.

This is the 993klifting the rc4wd loader for a size comparison.

WOOW Double vision.

[frizzen]

Those are such wicked looking beasts!

Wait, you made 2 of the big ones? Oh, now i get it...


That's really a mother wheel loader teaching it's young.

[modelman]

Wow cooper-great job. The machines look amazing. Are you selling one or was you just having so much fun building that you could not stop with one. Looking forward to the video.

I LOVE this picture lifting the RC4WD 870K wheeled loader. It really puts into perspective just how mammoth that behemoth of a machine really is!

[DADSGARAGE]

Nice job again Cooper!!!! Well done!!!
(Are you selling one of them??)

[Cooper]

thanks kp, I made one for a friend.

I finally got around to using a desktop computer because I has been almost impossible to access this site from my phone, let alone post any pics. so I am back at a learning curve again.











this is the project im working on now, making something useful. industrial sized soil screening plant.

[Rvjimd]

That's gona be cool! Can't wait to see how it turns out!

[skeeter]

That's AWESOME! Looks like it's well built to last a lifetime of useage.

Thats going to be a heck of a conveyor system. Are the roller supports 3D printed?

Yes they are printed in three pieces then glued together. The center roller shaft slips into place then the angled roller shafts lock it into place. Rollers are acetal plastic. Just using brass for roller shafts. The parts printed and shafts are very simple and cheep parts. So if they wear it's just a matter of pulling 4 m3 bolts and replacing the whole roller assembly. My plans (in my head) are to have the screen on a 5 degree angle with a hopper that has a short conveyor feeding the screen. Then all along belly of screen another conveyor transporting screened material under hopper to empty into another longer conveyor for spoil pile. Then the material that doesn't pass through screen empty to a conveyor to be piled. The hopper is going to be about 24" wide, wide enough for the haul truck to dump or two regular size dump trucks side by side. More of a quarry processing trommel verses a mobile setup.

[Zabco]

Sounds like a really cool setup, can't wait to see it in action.

[Cooper]

Things are just resting on each other. So just some idea if what this is going to look like. A lot more to do, two more conveyors to make. A lot of shrouds and covers. The big hopper to dump into, and I would like to have some sort of vibrating hopper to help with sticky materials.

[Cooper]

Decided to switch to aluminum.

[Cooper]

Ballistic nylon coated material that I may use for belting, way more flexiable to conform to the shape of the rollers









Jig I made for holes for roller assembly, can get them precisely located.



Simple concept of conveyor, can make any size

[Zabco]

Looking real good. I like the change to the aluminum, much cleaner look without all the holes the steel had.
