damper lever ht.

[Fred Sturm]

Hi Conrad,
	Another possibility you might want to consider: some dampers are sometimes 
hanging up on the flaired ends of the trichords. With these original 
equipment teflon Steinways, the trichords go way deep between the strings 
(unless someone ever had the time to trim them post-factory). Often the 
point where they contact the strings becomes compressed (insertion of strip 
mutes, or just course of playing), and the ends that hang below the strings 
flair out. And if a player has a technique where the keys are sometimes 
allowed to rise very slowly, or if he/she does a lot of half pedalling and 
the like, some of the dampers can hang up - contacting the string only with 
the flaired portion, not getting down to the rest position.
	To check if this is happening, with action out, work each of the trichord 
damper levers with a finger, letting it down as slowly and gently as 
possible. If there is any tendency to hang up, take that one out and trim 
the trichord legs. Better, replace the darned felts, they're old enough 
they need it. (And I'll get around to all of mine that are in a similar 
condition one of these days, too, when I get caught up <g>).

PS What almost set off the smoke detectors? The speed with which you were 
twisting wires, or the heat in your head from all that deep thought?
