Interesting to see/hear it run, nice build. Does sound a little more like crushing than tumbling, anxious to see the results.

Ran rocks w/out water to see if it would jam or a better term you used, 'carry over'. Did not happen, but it was a short run. Stayed away from rocks over 3 inches in any direction though. Sure sounds like crushing, more so in real life. the wedge shape may have something to do with that. Can't help but think the wedge shape increases the pressure. Wedges and unwedges, over and over, hmmm. Got to get gearbox oil, brass worm on steel pinion requires industrial grade oil, not really a car parts grade. Mobil 600W, for worm gears and steam engine cylinders !! Stopped by NAPA today and the guys cracked up when I asked for steam engine cylinder oil. They used to me, hide behind the counter,etc. That bowl is a little over 1/8 on edge, thicker toward center where less drawn. probably pressed 6 gauge(about 5/32). cover plate is 1/8. It should wear thru first in the center. no problem, just weld another round piece to it.

Mounted legs on it. Video starts about 50 feet away, sound more intense up close. Front legs stuck in sockets so they can be replaced w/longer legs if tilt desired. 1/4 HP turns it fine, gets hot at start, the gearbox oil must be thick when cold.

Looks somewhat alien or at least like an insect up on those legs. Now we need some before and after shots of what it is doing to the coral!

I stuck a load of little corals in it just to see if it wants to go over night. It is alien in nature. Maybe it will do alien work on those rocks. Will move it with the other tumblers. I apologize I did not take you over there. Another time.

Extremely awesome build, James. I'm happy that I learned a bit about gear reduction motors-Invaluable! Thanks!

What I was thinking of when I said carryover was larger pieces jamming against the outer edge. You watched your sizes, no problems. With the angled barrel I built early this year, the more fairly large blocky pieces I put in, the more the rocks held hands and stopped moving. Works good for smaller rounder things.

The interchangeable legs is a clever idea!

Extremely awesome build, James. I'm happy that I learned a bit about gear reduction motors-Invaluable! Thanks! It would have been better to have done most of the reducing before the gearbox. Motor on the small side. Like a 12 inch pulley on the gearbox where the v-belt is instead of the 5 inch pulley. And the sprockets the same size. The chain is used because of the gobs of torque. Notice the heavy beam up under the chain section, to resist bending from torque.

The interchangeable legs is a clever idea! I made a tumbler for metal parts. It rocks forward. Slowly dumping it's contents into a tub while it rotates when rocked with open barrel down hill. May weld a 5th leg on the back of this one so it can be rocked to tilt the other way for a gentle tumble. Anyway, tried making it minimal, so it could be reproduced with minimal parts. May tumble metal parts for contract tumbles or aging process for metal parts that artisans may purchase. A home biz.

With the angled barrel I built early this year, the more fairly large blocky pieces I put in, the more the rocks held hands and stopped moving. Works good for smaller rounder things. Those bowls come with taller outside lips. Preferred this one to be another inch taller for over 3 inch stuff. Mostly tumble less than 3 inches, so it seems adequate. It held more than I expected. It is full of 1.5-2.5 inch rocks. If smalls were added it may hold 45-50 pounds. the smalls may cause a jam w/the bigger rocks, not sure. It is making it's first overnight run. Let's see what the real world has to say.

Oops, will check. Got a steel cabinet up at the mailbox. They stash my packages in it. Will check it tomorrow. Got 200 carats of 20-25 grit diamonds in from Ebay. So 40 grams. Looks like they would cover a fair surface area. Cleaned up a 14 inch bowl. Guessing I could braze the diamonds on using puddles of braze(use gravity). Since it is not being applied to a cutting edge ?? Like do it in 2-3 inch patches till covered.

I apologize I did not take you over there. Another time. So much to see just in your workshop area Jim, I wouldn't have made it to JXR before midnight if we had gone down to the greenhouse. It was dark:thirty by the time I got there as it was. But at least that map pin didn't shift or I really would have been in trouble. I absolutely need to come back and visit. Between the rocks and your pitcher plants (always a favorite of mine)I need to impose myself for more than just an hour or so. If you are interested in joining us, Sunday a group of us are going to Summerville quarry to get more of that solid material (like the cab I showed you) . My friend Dave told me that Mr Patty has moved his entire operation up onto that bench and he is really chewing through that stuff. Experience has shown that the lower material is not as solid. So I fear this nice stuff may be short lived.

Want to apologize for Maggot(the dog) busting your nose. she nose buts like a porpoise, and broke someone's nose once. Something wrong w/that dog. Ya gotta get more of that brecciated material, so nice. Been to that site before and never found solid stuff like you guys did.

Emptying the tumbler, lazy way. it is coral and indestructible. Removed the lime and mud, a process done many times w/the coral. Will finish removal by adding broken up AO grinding wheel chunks for couple o days.
