[pianotech] balance hole jig

[Jon Page]

Something to keep in mind when repairing balance holes. Not only is the 
forward and back positioning important,
so is side to side. Look how the rear ends of the keys space. Moving the 
hole left or right will reposition the rear of the key.

Michael Morvan pointed this out to me when I had a set of keys which had 
the shoes reglued less than ideally.
