On my recent visit to Havanna Cuba w/the Piano Brigade, Paul Larudee <larudee@pacbell.net>
told me about a patent he has on tuning pins that are oversized in the
lower portion and standard 2/O in the upper half. The idea is to
have control over a fine tuning after restringing with oversized pins.
I am not familar with Denro's - if that is his patent, please forgive my
ignorance. It may be worth while asking Paul about them. Please
say <i>hola </i>to him for me if you do.

Hand reaming with a .010 undersize drill in a good quality tap
<br>wrench, gives about 140lb torque, and is very consistent. You
will need to
<br>tighten the wrench in the vice to prevent the drill from slipping in
the

Do
