One of the pressure bar screws on the upright I am restringing twisted off. The break is slightly above the pinblock surface, but well below the plate (about a half-inch hole in the plate). I think it is about a #10 screw. Just when things were going fairly well........ Terry Farrell _______________________________________________ Terry, If you're lucky and the remaining part of the screw isn't too frozen, (a drop of liquid wrench or protek can help here also) you can make a slot with a small cold chisel and back it out with a screw driver. If this doesn't work an Easy-Out screw extractor would be my next method. You will have to drill a hole through the body of the screw and the Easy out directions will give you the correct drill sizes. I've had to do this many times on the long action mounting screws of 1960's Wurlitzer verticals . Tom Driscoll RPT
