To make it I used an electrical conduit connector, plexiglass, 22 gauge sheet metal, auto body filler, paint, and leather. After about 200,000 revolutions this is what turned out.
This video shows me turning body filler on the inside of the jewelry box.
Step 1: Cut the bottom out
Once it’s off, I’ll continue to shape the body with 40 grit sand paper.
Safety first: Wear a dust mask. Watch out for the metal shavings that come off. They’re very hot. Be careful and work within your experience.
Step 2: Remove some threads
Step 3: Shape and Polish
As the piece polishes it gives the appearance that it stops moving. Once all the imperfections are polished away the sense of motion is lost and all you see is a shiny ring even though it’s still spinning at 2,500 rpm. It’s pretty cool.
Step 4: Solder in the bottom
I machined the circle down until it just barely fit into the bottom. Next I soldered it in.
