Just fill the holes with two part epoxy putty.

Subject: [CAUT] Capstan Repositioning

 

We have a Steinway M (c. 1960) here who's capstan line is askew
significantly.  The capstan on A0 is about 1/4" closer to the balance pin
than the capstan on C8.  The cap contacts the front of the wippen cushion on
A0, and the back on C8.  Dip at A0 is .420, dip at C8 is .390.  I am
planning on straightening this out this summer.

My tentative plan right now is to remove a piece of wood from the keystick,
about 1/2 x 1/2 inch, and glue in an insert for the new hole.  I was
thinking of using poplar for the insert.  Since I'm moving the hole such a
short distance (max 1/8"), I wouldn't think simply plugging with a dowel and
redrilling would work very well.  Any comments, criticisms, or dire
warnings?

Thanks,
Ken Z.
