The tuning pin is going to be hot no matter how you get it out.   Turn =
it out slowly and the hot pin contacts the hole for a longer time.   Tu=
rn it out quickly and less exposure to the hot tuning pin.   With a 1/2=
" drill it can't take more than a couple of seconds to get it out....th=
ink about it!!!!!

Ross, 

I totally disagree! How else are you going to get them out. Do it slow,=
 and MUCH more 
heat builds up!

Joe,


So, does this imply that the friction that generates the heat simply do=
esn't

have enough time to build up, vs. the slow removal, which may be slow, =
but

long and drawn out, consequently producing more heat?


Interesting......


Also, tried to email you about the keytop thing, but got rejected.  Any=
way,

I'll await receiving the keytop being sent to me first, and if it doesn=
't

work, I'll let you know.  And, thanks.


Respectfully,

William R. Monroe

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 w=
ith a

Reversible drill running at/or around 600 RPM. Test it for heat. (It wi=
ll

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 a=
round

15-20 minutes, using my 40 year old Wen Reversible Drill.<G>

(It too, will spin the shop, if'n ya ain't careful!)
