Wesley >From your description, it sounds like there is a crack in the pin block. So no matter which method you use, it will not?take away the crack.?If you want a stop gap solution, drive the pins deeper.?It will?tighten?the pins for maybe 3 or 4 years, at best. If you replace the pins with larger ones, you'll get?maybe more 10 years, at best, but it will also?widen the crack, before?you have to replace the pins again.?Although CA glue will fill the cracks, which should be a more or less permanent solution, unless more cracks will appear in a different part of the pin block.? I would suggest you do a combination of A & C, but? instead of CA glue, use impact resin. Tip the piano on it's back, remove the tuning pins in the effected area, and fill the holes about half way with?the impact resin. Drive in the same size pins. Some of the resin will fill the cracks, and some of it will come back out of the hole. Let the resin set for about 3 or 4 days. Remove the pins, and drive in one size larger. Of course the?best solution is a new piano. ?

The tuning pins of the bass section are tight.? The pins in the tenor section are loose to the point that a few are not holding tune like they should.? Most of the bottom pins of the treble section are on the verge of being too loose. ? There is a climate control system in the piano that has not?been in use for who knows how long. ? Three recommendations have been made by other technicians as to how to best address this problem: A.? Replace loose tuning pins with one size larger pins B.? Drive pins farther into pinblock C.? Treat with CA glue ? What is your recommendation? ? Thanks, ? ? Wesley Hardman Scottsboro, Alabama -------------- next part -------------- An HTML attachment was scrubbed...
