Hey groundsloth i would not recomend using a vib tubler i have tried many of modles with little to no success. I rockhound as another hobby. The bottle has to be held solid and usually tumbling in a tumbler is good for inside sickness.

thanks, I'm thinking of getting a rotating rock tumbler.I read some on another thread about packing the bottle in with peanuts. I might custom build a PVC pipe that fits on the tumbler and use that for that bottles.
