[pianotech] hour$ pinning

[Ryan Sowers]

Jim Busby recommended a version of this procedure at the Cal State
Conference recently. He's using the 2 foot long centerpins that Jurgen is
selling through pianoforte supply. He runs them through one direction only
and claims that they are more stable than the rubbing back and forth. I
apparently orients the wool fibers all in one direction and is more stable -
evidenced by the fact that you can work the flange vigourously and the
friction doesn't change.  Since the centerpin material is softer than music
wire its easier to maintain a rough spot on the wire.

Sounded worth trying!

Repinning a set of hammers is about a 2 hour job for me! You guys are FAST!!
