Not wood, but turned on the wood lathe...
I wanted to make a "rock stop" for my new cello. A rock stop keeps the long metal end pin on the bottom of a cello from sliding on a slick floor.
Cut a 4" circle from a scrap piece of 3/4" rubber stall mat, held with Cole jaws, flattened top and bottom with a scraper, beveled with a spindle gouge, roughed the bottom on a coarse belt sander to provide extra friction.
Had a red plastic plug for some unknown reason, designed to be installed/removed with a 1/2" socket wrench, had coarse threads on the side. Turned a hole in the rubber to fit with a parting tool, screwed the plug into the hole, done. Finish: none.

Thoughts:
- Quick, cheap, and easy to make.
- Livestock stall mats are made from recycled tires, may contain tiny bits of steel and other junk. Saw a few small sparks while turning.
- Rubber from a stall mat stinks when sawn, turned, or sanded.
- It was less fun then turning wood, more fun than turning concrete.
Should work fine until I can get to the stringed instrument store for a "real" rock stop. Then I can retrieve the red plug if I ever remember why I kept it.
