Hi all!
I recent got hooked on tumbling and would like a bit more predictability with what shapes I end up with.
Can you experts pointed me in the right direction? I'm working with rough I bought online that are about the right size, but I'm not sure the most efficient shaping method/gear.
I currently have a dremel 4000.
Thanks!
Jeff

There are many others with tons more experience than me but I have been using a tile saw and am pleased with the results. I also tried a bench grinder but I think that is a bit too advanced for me as I always end up cutting my hands to pieces whenever I get it out.

Does the tile saw work well for smaller pieces (2-3") or are you at risk of losing a digit?

I am using it to cut small pieces, most 1" or less. The continuous rim diamond blade doesn't cut soft things like fingers very well. So far I have managed to avoid being cut by the tile saw. You will definitely want to use safety glasses and hearing protection.

The point of a tumbler (rotary) is to shape and smooth rocks. Pre-grinding just speeds things up.

Definitely, Bob. I was just looking for a little more control in terms of output.

Don't be in a hurry. Stage 1 rounding edges and corners. Pre grind just speeds up stage 1 and you can make the starting shape. Without pre grind you might not get the shape you want but it should still look good.
