[pianotech] key position at rest

[Richard Brekne]

Hi Jon

My situation is a bit different... but the point is pretty much the 
same.  There is a 2 mm thick extra felt on the key end felts, the key 
rest rail felt (underfelt) looks to be non original and too thin, and 
there is almost no paper punchings under the balance rail felt 
punchings. Another good one here... there was so much paper under the 
black keys front rail punchings that the white keys were stopping on the 
black key front felt punchings. Very cute.

Well well... learned something new today.  Thanks for pointing out the 
article, and for your two posts.

Cheers

    OK, now to confuse things a bit...

    A few years ago, a dealer asked me to see what I could do with the
    high BW on a S&S B since the in-house guy's only thought was to add
    more lead to the already overly leaded keys.

    I noticed there was two rather thick pieces of underfelt on the back
    rail. This necessitated an inordinately thick amount of punchings on
    the balance rail to maintain key height. But the key end felt height
    was 1 3/8".  And the Magic Line was way too low, respectively.
