Usually the pin can be backed off enough to where = the coils are loose but not yet distorting or twisting the becket (the bend = of the wire where it enters the pin). Then pluck the becket out of the pin with needle nose pliers and pull it off the pin with a stringing hook, = or leave it on the pin and back the pin out with a T-handle or ratchet or = even a tuning pin socket in a drill -- use a variable speed one with slow = rpm. Sometimes when backing out with the coils still on the pin, the wire = will "find" the hole in the pin again and get caught and break off, so watch = it. Then do your shimming or reaming and turn or drive the pin back in. If the becket does break, you can insert a screwdriver through the = coils and pull carefully towards yourself with both hands to unwind the coils, then make a new bend. You won't have 3 coils any more, but the only alternative is splice or new string. I thought driving pins out the bottom was only for broken pins that can't be extracted any other way. There's a danger of separating the = bottom pinblock lamination if it's not supported on the edges of the hole. --David Nereson, RPT I don't drive the pin out through the bottom, I take a small punch from = the bottom of the block and tap the pin up to get the coil off of the = plate. If it were in the middle of the piano coil, beckett, or string = replacement wouldn't be a problem. The only time I have done this is = usually on pretty nasty pianos and you are trying to make it work. If = you are on A0, with a sharp string angle and 2 inches of wire past the = agraffe, the chances of getting that string off are minimal without = problems. Just pull the action and tap up on the pin, there are no = block problems and you can set the pin to any height that you want.=20 Phil ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
