I'll have to lower this one quite a bit just to achieve a parallel
underlever let alone to hit the magic line. I'm concerned that the top
of the raised underlevers will end up below the upstop rail even at its
lowest setting. <br>

My concern lies with the elevation of the pivot, meaning that I want
the key
<br>
to lift the underlever parallel to the key bed. The slots worn in the
key end felt
<br>
are caused by the underlever being at too much of a downwards angle at
rest.
<br>
Meaning that the pivot is too high.

This scrubbing is friction. Lifting beyond parallel is also counter
productive
<br>
because the underlever would scrub against the rear end of the lifter
felt.
