keyframe regulation

[Quentin Codevelle]

Hi George,

Yes there is a little knocking on the ends, but I cannot get a good frame regulation on the balance rail (with the knocking action) AND no knocking at all on the front rail.
Nevertheless, when I screw the 2 cheek blocks, there is no knocking at all.

Then, what should I do?

Q.

the bass and treble ends? The front rail of the keyframe  should be perfectly 
mated to the keybed, no gaps."
