Ratio question

[Jon Page]

>There's room to raise the key height..yes I checked the sharps.

Aside from making certain the sharps will not be affected by the
fallboard there is a more important consideration. That is the
depth of the front rail bushing on the pin. There should be at
  least 1/4" of the pin into the bushing at rest. Getting the key too
high on the pin can cause accelerated wear from the end of the pin
impacting into the cloth. In other words, the pin should be in as
least as far as the depth of the cloth.

So before you raise the key level, grip the f/r pin with tweezers
at the bottom of various sharps and lift the key to see what is there.
That info will inform you as to whether it is better to raise the keys
or lower the dip. Adjusting the dip is much faster (lower cost) than
to raise the level. Of course you have to consider the height
of the key slip too.

And around and around we go...
