Hi folks...

Ran into a really cute one... older Petrof 6 foot variant. I had a basic

action cleanup, lub, and regulation in front of me. I'd gotten so far as

to be back at the piano and started to do the rough in... and noticed 
real quickly in the middle area that there was this squishy feeling to 
the bottom of the key stroke... sort of like what you get if the damper 
stop rail is adjusted just barely too low... but it wasnt. The other 
clue is that removing key front punchings really didnt seem to help, or 
give any increase in dip or aftertouch. I didnt find the problem until I

noticed the keys wouldnt fall to the front felt punchings with the 
weight of the top action removed.

This may be easy to guess at now... but I just couldnt believe it had 
gotten out of the factory in this condition. Amazing ! 50 Q&A points for

the first to guess right :)

Cheers
RicB
