[CAUT] Center pinning

[Porritt, David]

I have to admit I don't have a good way to check pinning on the jack.
As long as it doesn't wobble, I just make it as free as I can.  The
repetition lever I hold the spring away from it and I want to measure 6
- 8 grams at the drop screw pad.  Before I had a good gram gauge I had
an 8-gram weight and I'd want it to move the repetition lever if I laid
it on the drop screw pad, but not move it when I put it on the height
adjusting screw.

Hey,

Does anyone have an effective and efficient method of checking pinning
on
jacks and rep levers? And what specs do you strive for? I know in my
previous work these two centers get less attention than they deserve if
I
want very consistent repetition. Thanks for any suggestions.

Like Mark Cramer I really enjoyed the time in Kansas City putting name
to
face and I look forward to meeting more of you in the future. This list
is a
vital part of my effectiveness and enjoyment of the workplace here.

Alan
