an actual piano question

[PNOTNR@aol.com]

With all the talk about what this list should or shouldn't be, and the merits
of testing, it seems like we're turning into the highway department: lots of
talk, but few are doing anything.  The discussion on ivory has been the only
"nuts & bolts" question of the past few days.  (like the one guy on the
highway crew actually USING a shovel)

So, even though this is probably not an advanced question for most of you,  I
need to know about using tuning pin reamers.  I'm repinning yet another old
upright, and this beauty has had about a dozen 3/0 pins put in over the
years.  If I go to 4/0 pins, I should ream out the holes first to make them
all uniform, but why would I use a reamer and not a drill bit for 4/0 pins.
 In the supply catalog (APSCO) they list a reamer for 4/0 at .285" but a
drill bit for 4/0 is .281".  (As you can tell, I've never used a tuning pin
reamer) Why are they different sizes?

Also, how do you use the reamer?  On a new block one is careful to control
the speed of the bit, the time the bit is in the block, the temperature of
the bit, etc.  Is this the case with a reamer as well?  Or can I just hog
away?
