Terry,
An interesting experiment: 1. Remove a tuning pin with a Brace=
 and Bit; immediately test it for heat. (it will be hottern' hell=
 a first touch.) 2. Remove a tuning pin with a Reversible Drill=
 as slow as it will go. Test it for heat. (it will be hot and=
 getting hotter.) 3. Remove a tuning pin with a Reversible drill=
 running at/or around 600 RPM. Test it for heat. (It will only be=
 warm, but will heat up rapidly as you hold it.DAMHIK!<G>) This=
 phenomenon is kinda like Microwaving a spud.<G> The answer is=
 spin them out as fast as you feel comfortable with. I usually=
 remove a whole set in around 15-20 minutes, using my 40 year old=
 Wen Reversible Drill.<G>
(It too, will spin the shop, if'n ya ain't careful!)
