[pianotech] Broken Hammer Shanks

[Dean May]

If you still have some of the old shank sticking out of the hammer, clamp
the hammer in your drill press vise with the shank pointing up. Rotate the
table until the shank is parallel to the hammer shank sticking up. You now
have the correct angle. Remove hammer, cut off remaining hammer shank and
sand flush on your disc sander, re-insert into vise and drill out remainder
of shank.

I went to service an old player upright today.  There are two broken hammer
shanks, which I took with me.

 

This will be my first go at angle boring, since one of the hammers is in the
bass.

 

I should have everything to do this project, but could I get some e-mails on
some suggestions, etc?

 

Thanks a lot!
