[pianotech] Today's Puzzle (actually yesterday, now)

[Joe Goss]

Hi,
You may have just made it work and made the client happy.
Just a guess and to add to things to look for:
It may have been caused by worn balance and front rail bushings.
Sloppy keys.

It is time to reveal the answer.  Many of you made valiant efforts to 
explain the cause, and I think some came close.  But I didn't recognize in 
any of those what I actually did.

There was not enough clearance between the ends of those keys and their 
wooden drop lifters.  So the end of the key would engage the lifter, and 
when you let go the key, it returned slowly--it had trouble disengaging.  So 
I removed those keys and could see exactly where the key engaged the lifter. 
So I sanded those spots off, and the problem was solved.

Perhaps we need to add that to the list of possible causes of sluggish keys.

You're welcome!
