(It must be in the archives.) It's a little less complicated to set= =20 up than the above, but kind of works on the same idea. Anyway, it has work= ed=20 for me and here it is: If there are any dampers which lift at the right time mark them with chalk.=20= =20 Ideally, find some in each section. (If not, see note later.) Remove=20 action. Put wedges under the damper lift rod until one of the marked dampe= rs=20 lift at exactly the same time that their hammer starts to move. In other w= ords,=20 insert your wedge, find one of your marked dampers, and put your finger unde= r=20 the wippen and lift until the hammer just starts to move. Is that marked=20 damper (one of the dampers that lifted at the correct time in the piano) mov= ing=20 before, after or at the same time as the hammer? It should start moving whe= n=20 the hammer moves. Adjust the wedge accordingly until the damper moves in=20 unison with the hammer. OK. Now you're all set. Bend the other spoons=20= so=20 that they, too, move at the same time as their respective hammers. Like=20 Conrad's method, this takes a couple of rounds to get just right. (Hope yo= u're not=20 working on a spinet!) Each time the action goes back in the piano, mark th= e=20 dampers that are moving too soon or too late, take the action back out and=20 reset the damper lift rod so that the correctly lifting dampers lift at the=20= same=20 time as their hammers, and then adjust your bad ones until they also move at= =20 the same time as their hammers. It usually takes me three rounds to get it= =20 right. =20 What if there are no dampers lifting at the correct time? Congratulations!= =20 You're going to make a little extra money, because you'll have to guess on=20 that first pass and that's going to take extra time. It seems like I get a= =20 few right on that first pass even when I'm just guessing, and then you can m= ark=20 those and start at the top. This may be where Conrad's method outshines th= is=20 one. =20 Next time, Conrad, I think I'll try it your way. (But tell me, how do you=20 get the damper rod wedged while it's in the piano?) Since I rarely contribut= e,=20 and no one mentioned the above method, well, here it is. =20 Anonymously yours, PianoTunaGuy ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
