I had the non-industrial unit. The bowl lasted for several batches using 120 and finer. I would not recommend it. I have the UV 10 now, bowl is way heavier. was your non industrial the uv-10 with the yellow stripe? just for clarification.

the non industrial barrel is half the price of the industrial. rockshed has the industrial pretty cheap but out of stock. everywhere else I look the industrial barrel is about 100 bucks. I found the non industrial for under 50. if using just for polish the barrel wont wear much. anyone ever used the non industrial (yellow ring) barrel? opinions?
I would like to go to 3 step tumble. 30 grit sc in rotarys. ao-80 in blue striped barrel. then polish in yellow stripe barrel.

So glad to hear that you got some proven rough. When I was getting started several members here offered to send me some and I took Garagerocker up on his offer and it made a big difference. I knew if something didn't turn out it was something I was doing and not the material. ohh man here I been buying boxes full all the while this garagerocker could have just sent me some free ones??? just kidding

wow wow wow. thanks. #22 made me think Rocky Horror (upside down). Hmmm....
I can see why. If I had seen the movie, I would certainly have recognized that. This rock shall be named 'Rocky'.
its very much a cult classic. there is no middle ground you will either love it or shut it off a few minutes in. the classic anyway. the 2016 version with the transgendered person from orange is the new black playing frankenfurter sucked!!! the girl who played janet nailed it. and ivy levene singing the intro. the rest murdered their songs. ps its a musical lol.

That looks like a good start for a nice machine, especially if inexpensive. Before you start it up, take the capacitor out and check it/have it checked to make sure it is good. It's located under the motor base. Ours was shot when we bought the machine, know of another locally. Bad cap will either not start the motor or will cause it to overheat very quickly. They aren't expensive. Thanks for the tip will check it out, turns on just fine dont think i ran it long enough to notice excess heat? Will look into it for sure,it cost me less then a tank of gas in my truck, cheap enough!grin ear to ear "it cost me less then a tank of gas in my truck" I officially hate you!

I don't see the barrel flange. I see lids, bands ie. hose clamps, and the whole barrel. but not the flange.

a little disappointed. after looking at motor speed its the high speed brass tumbler 1. but luckily I know a guy who might be able to turn out a double sheave idler pulley to cut that speed in half. I think I can I think I can. maybe ill use a piece of tyvar or nylon so it wont look like a cousin of woody (my homemade tumbler). maybe even make it a positive drive don't know yet. I have a high speed which I prefer. maybe ill give it a go at that speed then. should be alright for just coarse grinds (60/90 grit). I can up that to 30 grit if I build pvc barrel I would think. low speed is 20 rpm and high speed is 30 from what I read. I plan on polishing in the uv10 when it comes in. I have a feeling its gonna take a lot of rotarys to get ahead of that thing.

I think 4 and 5 are agates. I'm pretty sure 3 4 and 5 came out of the box of sj rough I got from Jeremy. they started off well rounded and went through the coarse grind in like a week.

I think I'm gonna repolish this whole batch and the one after it once the vibe comes in. I'm gonna use it just for polish stage for a while till I get another barrel. likely all my rough grinds will be in the rotaries even after I get the second barrel.

james the other stuff I got was screened and consistently sized somewhere around 30 grit. unknown screened grit on left 60/90 on right. i178.photobucket.com/albums/w250/notjustone/IMG_3801.jpgthis stuff looks unscreened straight out of the crusher. boss in that area of plant says basically we order x amount of pounds. they send us y amount of pallets to fill order. some of the pallets are screened some not. since grain size is unimportant in our application. I would imagine at the sic plant they crush down the rough then screen the crushings to different grit sizes. grain size in 30 grit is the same size as say 500 grit they are just screening out the different sized chunks. hence it cuts great on day 1 when the chunk size is larger. but as it sheds particles and gets smaller makes finer cuts. don't really think the big chunks will help as they will probably break down faster than something bonded. I only grabbed a couple scoops of this stuff (10 lbs maybe). I don't know really how this would work essentially you would be dumping in super coarse, coarse, medium, and fine. all at the same time. don't imagine the cutting action would be desirable. ill probably just toss this bag and wait till they have a screened pallet to restock lol. If you can get 30-40-50-60 sized particles you are in business for coarse grinding. Even #4 #6 #8 #16, etc. If you can only get 100-200-300-400-500 sized particles you are out of luck, such small particles will not shape quartz gems much at all. A screen that sifts out particles less than 90 grit may be a big help. Screen it on your work break perhaps. classifier screen for separating grit, I would use a no. 60-micrometer 250, .0097 inches, 60 mesh. About the same size screen head shops sell for marijuana pipes. That would pass the small stuff and hold 30-40-50 grit. Cheap classifier screens: obviously your mom never had the spitting and sputtering faucet problem. headshops hahahaha. hell this stuff is so coarse I could use window screen to get the biggest chunks.

Want to see who has the ugliest slab? Here is my offering. I have named it "Uglisite". This stuff is hard. Quartz wont scratch it. Note how the image is reminiscent of toxic waste gently flowing into a slow moving stream. The greens have a decidedly mucus appearance and the random streaks of nasty brown material highlight the orange vugs of rust that are incoherently banded through the slab. Truly this is the ugliest slab I have cut. Uglisite by Glen Ray, on Flickr I lost a stone and a half recently. Looked a bit like this! (sorry too much info) This brings back bad memories... its beautiful in its own special way. kinda like the ugly kid who only his mom thinks hes cute. or some dog breeds

unscreened sic Is this the bulk SiC your company receives notjustone ? Do you think it is 30 grit in size ? The chunks should be no problem and actually a bonus, and yes should break down. Trial by fire ? Try grinding with it ? The pavers must be antislip, only thing that makes sense. james the other stuff I got was screened and consistently sized somewhere around 30 grit. unknown screened grit on left 60/90 on right. i178.photobucket.com/albums/w250/notjustone/IMG_3801.jpgthis stuff looks unscreened straight out of the crusher. boss in that area of plant says basically we order x amount of pounds. they send us y amount of pallets to fill order. some of the pallets are screened some not. since grain size is unimportant in our application.

65% SiC and the rest foundry needed stuff like graphite and ferromanganese... Curious how much a 50 pound bag costs. Another RTH member mixing SiC for steel operations. His company ordered in SiC 30 in bulk. SiC 30 would work for tumbling. Noticed the 65% content. Seems like they are even making landscape pavers with high SiC content ?? Why ? antislip?
