I tuned a very old upright yesterday, and realigned a few hammers. In order to make it work, I had to file those, as the grooves were quite deep on all of them. I asked the customer which "sound" she preferred, and she just didn't know. What is of interest to me is that the filed hammers seemed "softer", the deeply grooved ones brighter. Now I talked to one tech today, unidentified, but not unidentifiable, resembling Jim Bryant very much who suggested that by filing them, I had eliminated the "muting of the fundamental" caused by grooves, thus the ending sound had more fundamental, and less higher partials. I was expecting the sound to be louder, and so was surprised. Does someone have a short explanation that might enlighten me about filing in general, are the "rules" different on an older piano, and what I should expect. It strikes me........ than when one files the grooves out, one gets to less compacted felt, and a more mellow tone, softer, perhaps might be expected, though what I've heard is that the sound should get louder. I'll be appreciative of enlightenment. thanks les bartlett ________________________________________________________________ YOU'RE PAYING TOO MUCH FOR THE INTERNET!
