[pianotech] Hammer pre-file jig

[Jon Page]

I finally got around to making a hammer pre-filing jig, thanks
to the disposal of a HF Miller grand the other day. Bi-folding
key covers come in useful for many things.

Pictured are 16#, Wurzen felt hammers by Ronsen.
(Finally getting to use 2 y/o stock). They're filed to 600 grit.

The tray pictured on the left holds the hammers during
the drilling and hanging process.
