I think that buying the first set, and then replace the cord on the old set at your own convenience, is a good option. Mind you, you would have to do a set of each, which you might never use. But all they cost was the cord, some glue and some time at home. John M.

Most everyone told me that they'd replace the flanges. Paul McCloud suggested that it's easier to replace the cords. While I thought I had a standard cord replacement job on a P2 today, it turned out it was cord replacement on the non-plate variety! As I had already blocked out a sizeable chunk of the day to do this job (with a bike ride scheduled afterward..) I figured I'd go ahead and give it a try. It took right around 5 hours. Same basic formula: Remove rest rail Take hammers off the rail, flanges and all remove old cord debris from slot, but I've found that being overly meticulous about this step is a waste of time wind your replacement cord around a 5/8 inch dowel many times Cut lengthwise to make cord pieces of the proper length Glue one side Go back and glue the other side reattach spring screw hammers back on to the rail replace rail PUt action back in piano Go home Have a glass of wine Notes: It's harder to glue the threads to the flanges as a moving target hanging from the butt assembly than when the flanges are firmly screwed to the hammer rail. Keep a sharp blade around to keep the flange and the hammer assembly detached when excess glue gets slopped in places where it shouldn't With better gluing technique, I expect that this job could realistically be done in 4 hours. Next time, I may try replacing the flanges, though I suspect that will take longer. I'm going to bed. I'll probably dream about applying glue to empty slots....
