[pianotech] Key Leveling Time

<How many of you level keys with the stack on, cutting a wedge out of 
the punching and inserting it from underneath the keyframe?

I do this for final and touchup passes. I've tried not cutting a wedge, 
and just slitting it, but as touchup passes are wimpy green and white 
punchings, maybe some pinky's, I struggle with inserting split punchings 
and resort to the wedge.  I've never been able to get split punchings to 
behave, either with or off the grain of the paper.

I made some simple props to hold the action up at an angle while the 
keyframe is half-way out of the action cavity, and use felt wedge mutes 
to hold the keys out of the way. But still, its a time consuming process 
for me.

On a 1 day on whilrwind (ha) on-site regulation, depending on the skill 
level of the pianist, I minimize the pickyness of keylevel. This allows 
me to spend more time in other places where the regulation will get more 
bang for the buck...1 day for a full defferred maintenance action is 
really pushing it hard...gotta prioritize.
