the x factors could be used the change the poundage needed to close into another number that would represent gripper difficulty. so, a 200# gripper that rated out to a 7.4 for example would beat a a 7.3 that had a closing poundage of 201#. that's what people are trying to say. scoring wouldn't be based on 2 different numbers for each gripper. these numbers and factors would all be combined so that dificulty was rated, rather than poundage to close.
of course, we aren't really even close to figuring out and measuring all the other factors.
^Exactly. This isn't something that you whip up overnight. Nobody's even remotely suggesting that we scrap every scoring method we use now.
What I would like to see is to take two grippers - one with a hard but consistent sweep, and another that binds like crazy like the MM3 - and just collect the poundage at small intervals of distance. I'm taking a guess that the first would exhibit more ideal spring behavior (linear), while the other would depart from that towards the end of the close and start to peak a bit. They need not be the same closing strength, but that would be a plus.
Magnus, I will do the experiment you suggest and I have the ideal grippers as well.
How many increments do you want between start to closed?
Now I would like to bring up something I discovered today from a retired math professor at Henderson County Junior College
in Athens Texas. I explained to him what was being discussed here and even encouraged him to go to the GB forum and read
the exchanges on this subject. He reminded me that the total force to close the gripper can never be left out of any percentage
formula one may use and that the "x" factor number can never be higher than the total force number. It was beyond him as to
how the increments between open and closed could be put into a formula that would be beneficial to the user. Nothing will change
how much force it takes to shut the gripper.
Now we have Tommy and yourself disagreeing over how an MM3 felt at the end which is a subjective disagreement that has
no formula to allow quantification into the mix so that the disagreement can be cast into the objective realm and the issue
I'm pretty much done with arguing over something that doesn't yet exist but I'm far from done on testing what's suggested
here! Anyone else want to throw something into what Magnus has suggested so that I can accomplish several tests at one
time? I'm game guys! I love testing and experimenting anyways! I must say I won't run an arbitrary test that is not conducive to
this topic just for the sake of satisfying one's curiosity on a certain aspect of rating grippers. i do like what Magnus is suggesting here though!
If conditions are right and humidity levels are low this Sunday I will even video the tests!
BTW, some of my remarks may seem cocky and arrogant but that's not my intent here. I'm actually trying to throw some humor into
a serious topic worthy of serious discussion but hey we need to have fun too guys! Agree? Hope so!!!
Thanks again to everyone participating in this thread!!!
