Tuning Pin Hole Reamers

[Walter216@AOL.COM]

For What It's Worth:

I agree with using .30 caliber rifle brushes on the holes, especially if 
you're going from 2/0 to 3/0 pins.  (How is the torque now?  Are you 
restringing because of low pin torque or aged strings?)  If pin torque is too 
low, I would go to 4/0 pins & use a reamer, observing the cautions about 
getting it too hot-ruins the block & the reamer...If possible, use a drill 
press w/ adjustable angle base @ 700-900 rpm & Vortec bit cooler.  Better 
yet, put a new block in the piano & save yourself the worries.  A new maple 
blank is only $60 + a day's work to install.  I hate betting  $1500-1800 in 
restringing work on an old piece of maple plywood.
