I'm not completely clear on exactly the situation, if the screw head is
still big enough that you can't get the pressure bar off I've cut a new,
deeper slot with what ever will work from a hacksaw to a dremel tool.
Otherwise Mr Joe is exactly right, I had a Steinway console from the
50's last year in which all but one of the tenor pressure bar screws
were actually broken off in the wood. The call came because the tenor
wouldnt hold a tune and several different tuners had tried. Drilling out
the screw with what is essentially a mini hole saw or plug cutter is
quick and painless. You can do this with brass tubing for one time use
on broken bridge pins as well.
