If you spin tuning pins out, you're going to scorch the holes in the =
block.  You don't want that.

  Joe,

  So, does this imply that the friction that generates the heat simply =
doesn'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.  =
Anyway,
  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 Peterson said: "I also would like to get opinions as to how =
fast, slow
  to remove them to
  avoid over-heating and/or scortching the pin block. I know the pins =
WILL get
  hot no matter what, (I tested this by using the very lowest rpm =
possible
  without stalling) but it seems to me that the main thing to avoid is
  "spinning" the pin in place when/if it stops rising outward during =
removal.
  I try to use lowest rpms to remove each pin, then releasing trigger =
when
  it's almost out, letting the drill slow to a stop at which point the =
pin
  drops out...ideally. thoughts?

  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!)
