Greetings, << The main problem is the balance rail pins. They are very loose in the rail and the keys are very pulley. I can glue size the balance rail holes on the keys, but do any of you have experience either replacing the just the rail, or should I glue size the holes? >> I believe that a swab of West Epoxy in the holes should tighten them up considerably. remember to put a black stripe (with a Magic Marker), along the front of all the pins so that your key spacing is not completely screwed up when you return them to the holes. Also, keep the height the same! I did this once before and the pins are still tight after approx. 15 years. A strip of masking tape along the bottom of the rail will keep things a little cleaner.
