[CAUT] TIP OF THE YEAR!

[Jim Busby]

Fred,

You can indeed see very minute movement with this method. Drives me nuts
sometimes... One thing I have found using this technique is that I have
a tendency to put too much travel paper on to correct the problem. I
don't know why that is, but now I use 1/2 as much/as far in etc. and I
can usually get it right w/o the "pendulum effect" (Too much one - too
much the other...)

HI Keith,
    It's a matter of technique. Very rapid up and down motion of the
stack,
from resting on shanks (ie, the wipps are resting on the knuckles) to
approximate string contact distance (jack heel has contacted let off
button). Up, down, up down. Looking for any sideways wiggle. It's a
difference between static and movement. As the job is refined, the
tiniest
movement becomes more obvious.
    Watching the hammers or shanks while they are rising means a more
complex visual challenge. You are watching for an angled movement versus
a
perpendicular one. Yes, you are watching distance between adjacent ones,
but
which one is correct? (Like temperament tuning <G>).
    Reference lines on an attached rule certainly solves the reference
problem, but at a cost in efficiency: needing to get your eye in the
right
spot to observe movement (or lack thereof) relative to the line. Might
be
more natural and efficient for some, but not for me.
    I'm not proselytizing, trying to convert everyone to my current
method.
Just sharing something that has been working really well for me lately,
making a job a lot easier and more accurate for me. But we each have our
own
things that we find easier or harder.
