BACKGROUND: We plasma cut a lot of parts like steel tabs and large washers. The cheap vibrator type tumblers and roller driven tumblers were just not effective and could NOT handle the heavy steel parts so..... we designed our own heavy duty chain driven tumbler. This tumbler design was so effective that we decided to share it.
