There are about 2-3 mms between the keyframe guide pin and the plastic keyblock plate, so there's definitely knocking and I can lift the frame about 2-3 mms with the blocks screwed in. I can't lower the plate and I don't want to bend the pin. Am I overlooking something? Daniel </blockquote></div> I'm certainly no an expert on this -- at all. However, I recently had what sounds like your situation. Shimmed up the front of the stack. The stack was causing the keyframe to twist, pulling the treble side up. It helped that I had read about this on Pianotech and happened to remember it. Thanks to Ed Foote, as I recall. -- JF
