[pianotech] Acro guide rail fixed

[tom]

Paul,
	You are exactly correct about the damper barrels- block being a
tight fit over the pins in the pickup fingers. Drilling works, but I had
some leftover damper blocks from a Steinway upright action rebuild and the
holes are bigger. 
 	I have a few in my little spare parts kit just for the Acro task.
The rubber mute idea that Jon has mentioned works quite well also ---just
not this last time for me.

I carry a handful of damper barrels/screws in a film canister in my supply
box in my car.

Damper blocks don't always slide over the pick-up fingers well. To be on the
safe side I drill out the holes in the barrels. A couple for each rail
section will do.
