Good idea Joe.  I've also dreamed up many other ways to streamline the process, or take weights out of the equation, etc.  Thank you for experimenting with this.

 

I'm saving my money for a computerized rig like this.   :D You could map anything you wanted:

 

 

 

(If you know how to make this happen, please contact me. :flowers:   )  

Only problem with that setup is the fore is being applied at different point on the handle through the test (at the end it is ~halfway up the handle.

WARNING: NERD ALERT!

 

If we had a graph (plotting lb force vs. '% close') showing three grippers:

1. a gripper with RGC of 180lb but with an easy sweep

2. An 'ideal' gripper with a straight line force / % close graph, also RGC of 180lb

3. A gripper with a hard sweep, but RGC of 180lb

 

Then the easy sweep would deviate from ideal, showing a plot under the 'ideal, the hard with deviation above ideal (except, of course at start & finish where all three examples would be the same: zero lb at 0% close and 180lb at 100% close).

 

So what I am suggesting is that a measure giving 'Hard' or 'Easy' compared to ideal would be obtained by comparing the area beneath the plot and expressing this as a percentage of 'ideal' so 'easy' would have an area less than that of the ideal, 'hard' obviously would be greater than 100% of 'ideal'.
