I've noticed several people here hobby with wood. Here's an idea for something different, fun, and....very little profit!
If you have a hobby lathe, how about copying the cheap plastic auto shift knob ('03) in wood?
Also, if anyone is interested in one, say so here.
I'm not good with wood, but since there are none available, I had to make mine ('02) from a wooden egg from a local hobby store.[:I]
