Isg And Coc #3

[grumpycuban]

I just bought an IGDA to change things up a bit and wanted to ask everyone with an ISG.What is the equivalent of the COC #3 in pounds on the ISG? What about the #4(for negatives)? Thanks for any help I may get. Jose

If you have 2 springs, positions 6 & 9 will get you the #3

and 10 & 12 will get you 345.12 lbs. which is 20 lbs. shy

of the #4.

To replicate the #4 you'll have to get a 3rd spring.

With 3 springs, positions 4, 9, and 12 will get you 365.885 lbs.

After joining the board I found out that the ratings on grippers

doesn't actually mean if you hung 365 lbs. on the handle the handles would touch together.

The poundage is actually way less than what they're rated. I don't know where the

actual fiqures come from, but I'd love to hear someone's explanation.

Hope this helps.

Granted I have no clue about this...

But perhaps the poundage comes from a measurement at a certain point along the handle. If there is a small amount of leverage on the spring, then the poundage required to close it would go up. Maybe IM measures at a certain point.

The generally held notion is that the IM gripper ratings come from a test point under where your middle finger would be, or about the middle of the handle. Thats what I remember from previous discussions about this.

10-12 is around a #3 IMO

Thanks wes, that feels more like a #3, but any idea about a #4?

NailBender, I think you misunderstood my question. I wanted to know how to simulate the strength of a #3 and #4.

Just because you put 197 on an ISG doesn't mean it feels like a #3. It's actually waaaaaay easier on the ISG, but thanks

for trying to help. I appreciate it. Jose
