I am doing my very first grand regulation. After carefully measuring =
the felt
punchings thickness, I ordered new ones and replaced both front and =
balance
rail felt punchings because they were shot. I also replaced keytops. =
The new
keytops were .03 thicker than the old ones. I knew from the beginning =
I would
have to compensate in the regulation for the new key heights, and =
probably
some of the residual miscellaneous felt height as well.

;
At the job site I put lead weights on the keys' backs and levelled the =
white
keys and then set the key dips on the whites as well. Then, because I =
am green
at this, I removed the the keyframe from it's bed and replaced the =
stack,
screwed it down and when I slid it back in, the keys were all =
different
heights(!) What went wrong? Are the keys supppose to do this. Are my =
weights
too heavy? Must I consider keyweight when leveling keys?
