With a rail across the key tops you can quickly learn to guess the amount of
punchings you need for each low key.  You can get an aluminum "angle iron"
on the order of 1/2 by 1/2 inch.  Prop up #1 and #88 to the height you want
and support the "rail" on these two keys.  First make sure there are no high
keys the rail is pressing down on.  Then see what keys are low and place
what  punchings you think are enough on top of these low keys. Then remove
the rail and put punchings under the key.  Then replace the rail and see how
level the keys are.  You should not have to do this more than 3
times....unless you are very considerate and go back and place the paper
punchings under the felt punchings.
    There is a debate about whether this needs to be done.  What is the
difference between a paper punching above or below the felt punching??  OK
the key rocking up and down should be on the felt punching not a thin paper
punching, right?  But is there a consideration of the key rocking on the
felt punching which is rocking on a very thin paper punching?   If so place
the ultra fine paper punchings under a thicker paper punching under the felt
punching.    BOTHERATION.         ---  ric

ps the reason why there is not a scew up balance rail pin to level keys is
because the blance rail pin must be tilted a little front to back and also
sideways if necessary.   If such a pin is screwed up or down it would wobble
out of the other positions.
