A lot of what I have been tumbling is scraps from back when my dad did some cabbing and slabbing. I have quite a few very nice tumbles from the slabs and remnants.

I did that a few times. They broke though. Were you running them in a slurry to protect them or following tumbler manufacturer instructions?

The pic is on Roaring Fork River above Aspen. I guess I will post the full pic.

Here are the results of my 1st attempt at tumbling slices. 1.5 lb barrel, 7 days, 2 Tbls 60/90, no slurry thickener. Results = wasted time, very little smoothing. The entire batch after cleanout, with slices on top of the smalls: All by William Criley, on Flickr The slices: Slabs by William Criley, on Flickr As you can see, there was no rounding/easing/smoothing of the edges: Edge by William Criley, on Flickr The saw marks on the flat sides were slightly less noticeable, about on par for one week in one of my itty-bitty barrels. Slice by William Criley, on Flickr I'm thinking I had too many slices in the batch. Took a few out and ran them again...with some kitty litter, this time.

Nice pink granites. They can be a challenge to avoid under cutting as the felspar is softer than the quartz.

Run rocks longer than a week n coarse including slabbets. Yep. I've learned it usually takes at least 3 weeks...even for pebbles that are already fairly smooth.

I've had good luck so far with the granite landscape pebbles the grandkids and I have picked up. I have a few running in a 1000 grit stage that didn't undercut. The pink ones and some that are black with white specs seem to work out the best.

I have run rough rocks in the coarse grit stage for 7 months before they were ready to move on. "good enough" takes significantly less time. Rock tumbling requires patience. Lots and lots of patience. Hope the rock tumbling hobby survives the instant gratification generation of youngsters we seem to have these days.
