oh god no, that bridge will fly up and hit you in the face!
an easy trick for (let me guess) removing a broken-off screw in the wood;
get a bit of brass tubing from the hobby shop, sized just bigger than the screw shaft in question. cut a section about 2" long, and file little "teeth" into one end. chuck it into your hand drill, set to
unscrew, and slowly drill down around the busted screw section.
chances are, it'll grab the screw piece part-way down and back it right out, saving most of the screw-hole.
