Dear List, I have a Vose grand that needs about 20 pins tightened. I am not in favor of doping and the plate holes are so small that there is no room to put in oversize pins. Can I drill out the holes slightly, if so, how and with what? Or is there a better method? The owner is not willing to replace the block for cost reasons. Paul Plumb, B.Mus., Plumb Pianos
