Any suggestions on an efficient crushing/tumbling process?
Besides a baseball bat --
I had an idea that you could cast a
concrete block in a 5 gallon
bucket and put a threaded rod or hook in the concrete before it set up. Then un-mold the block, fasten a chain or cable on it and rig some sort of pulley or fulcrum to raise and drop it over a barrel filled with glass bottles. You would want a way to do it from a distance or rig a guard over the top of the barrel to keep glass from flying out and potentially putting an eye out, of course!
As for polishing, it is a pretty easy process to make a gigantic rock polisher out of old tires. Check this out, for example...
This isn't the best one I've seen by far, but it is one of the most basic and a good place to start. Have fun!
