I thought I would try a fun little project of making my own brass tumbler. Now, I'm scratching my head trying to figure out how to make it work.
I'm using a drill with a rubber mandrel/arbor to turn a belt from a vacuum cleaner, which in turn spins 2 "rollers". This design appeard to work fine until I added the container with the brass and media. At that point, either the rollers turn but the container won't or the mandrel turns but doesn't turn the belt.
The container with the media is just a plastic jar that would hold small snack items. I thought it might just be too smooth so I scuffed it with some 60 grit sandpaper to no avail.
Here are pictures of the setup. Any suggestions are apreciated. Thanks in advance.
