I have read with interest the comments on repairing stripped wood
threads.  A few notes:

- Drywall screws are not only inappropriate, they are brittle and
  break easily; good luck getting them out!

- Leather in wood holes sometimes contains chemicals that will rust
  screws.

- You can avoid stripping the threads by heating the head of the
  screw with a soldering iron.  When the screw cools, it will break
  free and can be removed without damaging the threads.

I agree that the simplest method is to cut cross grain plugs and glue
them in to secure things correctly.  Also, I draw a picture of the
piano on corrugated cardboard and insert the screws that I remove into
the appropriate place on the drawing.  That way every screw goes into
it's original hole as needed. As mentioned before, always reverse
thread the screw [turn it backwards] until it clicks before threading
it into its hole.

I enjoy the comments on MMD.  Keep up the good work.
