I was cleaning out my attic the other day looking at some of my old projects and found and old Rock Tumbler i used when i was younger. I was thinking of giving it to my son who will turn 12 in may, but before i do i thought i would update it a little. Some of the problems i had when i used the Rock Tumbler was sand always found its way out so i had to clean it often. This Rock Tumbler didn't have adjustable speed so i was going to add a dial for that. I also would like to add a time and day that was programmable so he could watch and get a good idea when to add the next course of sand.
So my idea for a show is an updated version of a Rock Tumbler.
