<p>Hello Paul,
<br>When you have heated the screws, give them a short sharp whack with
the
<br>screwdriver inserted using a small hammer. This may break any bonding
as
<br>well. After doing this, apply pressure with the screwdriver first clockwise
<br>as if you were trying to make it tighter, and then apply pressure
<br>anticlockwise. Keep going forwards and backwards like this until there
are
<br>wider and wider movements of the screwhead. You will get a feel as
to when
<br>the screw is turning in the wood as against the head just twisting.
Also
<br>there is a product there called Wynne's Pry and Dry. Give those screws
a
<br>liberal dousing before you start.

I suppose Wynne's Pry and Dry is a British product and we can't get it
here in the U.S. Anybody know an equivalent product we can get stateside?
I need something for those frozen let-off screws in old pianos. I've
tried heating. They still break. I've tried Protek. They
still break. --David Nereson, RPT, Denver
