[CAUT] Gram Tension Guages

[David Love]

I prefer swings since I have a hard time telling exactly when the gram gauge
starts to move.  Seven to eight swings is what I like and the flange should
not fall of its own weight until the screw is inserted.

Andrew, List,

FWIW, Rick Baldassin says grams only. Carl Teel Swings only. Both are
excellent technicians who work closely on a lot of projects. 

Today I did some testing of swings vs. grams on an M action we just got
into the shop; (I had another RPT verifying, and I used a Correx gauge)

Hammer#8	2 swings 	7g
	#18	2		5
	#28	3		3
	#38	8		1
	#48	2		5
	#58	2		5
	#68	2		4
	#78	3 		2
	#88	4		2 

This is typical of the results I've had from similar tests in the past.
It's VERY inconsistent and difficult to draw conclusions from this.

Baldassin says grams matter most because of the touchweighting issues
involved and he feels it produces a more consistant feel in the action.

Teel says it's a functional process and if it doesn't swing consistently
it won't feel consistant.

What is best? Both can't be right, can they??

Ladies and Gentleman,
I'm looking to bite the bullet and get one of these.  What are your 
preferences for assessing/gauging pinning problems etc.  Swinging? 
Measuring? with which tool: Correx/Neuses/other?
