Dear List: I have been having a little trouble with trichord felt in the last two pianos. Namely, on a soft blow or on a gradual return on the key or sustain pedal. Several trichords do not seat, and the note sustains. On a hard blow, they will seat. Namely, is there a way to repair this without tearing off the new felt? Can I comb the felt or something? I have noticed that the old style felts employed a blocking felt in the rear. I have been using trichord both front and rear, but have not had this problem till recently. I have oriented the new felt the same way each time. I dare say the method of installation is correct. I orient the damper head over the new felt and then tighten the block. Then I remove the felt and replace it with glue. I solved the last problem by using upright trichord felt. The wood backed kind, modified. The narrower slopes seem to seat better, even tho I was using "grand" trichord in strips. Enough already. Any ideas? Yours Truly, Sam Grossner Chicago.
