You'll feel=20 it. And if you can't feel the damper weight that way, see how the keys fee= l=20 when you play with the damper pedal depressed. =20 Yes, manufacturers all have specifications for what should happen where and= =20 when. But why would they put spoons on the underlevers if they weren't=20 expecting techs to use them from time to time? And bending the spoons has=20= no=20 effect on the operation of the pedal, unless I really am missing something=20= here.=20 I did adjust the trapwork-stop capstan down a bit. =20 I'm not saying this is the perfect way to change touchweight(real or =20 theortetical). I will say that I was pleased with the result, and so were =20= the=20 clients. I'm just relaying information from personal experience. =20 =20 Dave S. =20 In a message dated 1/18/2006 11:19:22 P.M.
