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!) Regards, Joe Garrett, R.P.T.
