Talk:Tumble finishing

Untitled
here is a good source of more information on this topic http://geology.com/rock-tumbler/

Removed the following section because it is too specific to some very particlar arrangements and the formulation wasn't cited well enough for the limitations to be clear. The barrel ... "rotates — if round — at about $$\frac{132.8} {\sqrt{D_{in}}}$$ (where Din is the inside barrel diameter in inches) RPM. A hexagonal barrel will rotate at about $$\frac{79.7} {\sqrt{D_{in}}}$$ RPM ."

Proposed merge
I propose merging the unreferenced, orphan stub article Rock polishing into the article here. The stub article coverage largely overlaps the coverage here. Reify-tech (talk) 20:34, 25 April 2017 (UTC)
