[glatt]

The sanding drum I made was vibrating out of balance too much. I realized the threaded end of the bolt just wasn't being held straight by the chuck. I needed a smooth surface for it to grab. So I dug around in my scrap metal pile and found a perfect rod that I think came out of an old ink jet printer. I pulled out my grandfather's old surplus Navy tap and die set, and got to work putting some threads on the rod.
