Had the UV10 running 2 days with 120/220 as per Randy's great vibratory tutorial. I rinsed everything well and put the still-damp ceramic media back in, and all the rock back in as well. Added 6Tb of 120/220 and will let it run a couple days. One tidbit I did find was that if I got it too "soupy" (I did once by accident) - you can add in more dry material. Don't keep adding SiC or you will end up using a lot. Only use the minimal water via a spray bottle that you need to. The "soupy-ness" happens very suddenly, so if things are starting to move, wait a few minutes and see if it loosens up. Anyway, pics: Before the rinse:

Yep, you also want to avoid adding extra grit because that fine grind grit ( coarse is even worse) will chew the heck out of your UV-10 tub pronto and way decrease tub life. You want to use as little grit as possible and run it the shortest time possible to achieve the desired result, or you'll be replacing that tub in a year or less.....Mel
PS: Those shapes are looking very nice and smooth!

What Mel said. 6 tablespoons of grit in a UV-10 sounds excessive. I use 3 tablespoons and run a 3 day cycle. 3 days should be plenty of time to break down your SC grit provided that you maintain the moisture.

Yeah, I just re-read my tutorial. I have perfected my methods a bit. Now I simply pour the grit in the vibe (while running) a little at a time until rocks are completely gray. This probably takes about 3 tablespoons. If this doesn't turn them gray, add one more. If they get dry during this process, spray a little water in and continue. There's no real scientific way to do this since there are too many variables (how full the bowl is, the size of rocks being tumbled, amount of pellets added for cushion, ect...) I just kept on trying new ways until I got it right. My first bowl lasted 4 years. EDIT: I went back and modified the tutorial, thanks guys for pointing this out. ;D

Cool, thanks all for the input. I *did* add 8 TB the first time and 6Tb today. I'll let it run a couple days and It should be done with stage 2 anyway.

Good golly Randy, four years! You must have got a super thick bowl for your first one. Even my bowl that was only used for prepolish and polish only lasted two years before the bottom collapsed the other day. I guess I've got to shorten my running time per cycle...Mel

Biggest killer of any brand of vibe tumbler is too much water. It causes grit to settle to bottom and wears a hole about 1/2" from bottom. By the way, Gy-Roc 10 lb tumbler instruction calls for one tablespoon grit. I don't know how that works in other brands but would try less grit.
