Re: Bought non-industrial Thumler by mistake

The tumbler you bought will work great for the 2nd, 3rd and polish steps, but it is hard on the bowl if you use a heavy grit. I have several of the Tumble Vibe TV-5 vibratory tumblers and they work great. I usually do my grinding step (60/90) in a rotary tumbler unless I am trying to retain a certain shape, form or size. Vibrator tumblers don't remove material as efficiently as a rotary tumble with the large grit.

The main advantage with the vibrators is that they don't remove much material and work much faster than the rotary type.

I have found that I get much better results if I use the rotary for the initial grinding stage, which can take several weeks depending on the rock type. I then put them in the vibrators for the second and third steps and then back to the rotary tumbler for the final polish. I also use the vibrators for the finishing touches on the different cabs I make.

Have said all that, you have a very good, reliable machine that will work in all steps if you don't mind ruining your bowls. Also, don't use the same bowls for step 3 & 4 that you used for grinding. I hope I haven't totally confused you. David
