funny enough, i just finished making my own wood shift knob and then stumbled upon this thread.
sorry the pic isnt great, i used my lame cell phone camera
i'm not exactly sure what species of wood it is, maybe bubinga or cocobolo, i just know it's really hard and it has nice graining. i finished it with 7 coats of varathane with sanding in between coats and then polished the final coat to get it really shiny.
For the threaded insert, i actually cut the threaded insert out of the original plastic mazda shift knob using a bandsaw and then epoxied it in, though i would like to find some real inserts and make some other shift knobs, maybe using ebony or birds eye maple.
