I put the strap with half on the knuling as close as I could get. Let the rest hang over the rounded edge. Slid the tug though the pipe until the spring just missed touching, The tug would bottom out on the pipe. My tugs can be compared to the same point but it may not be to reliable on another persons set up unless I give you exact measurements of my set up

There are two things that I hope to redirect here. This is general information; it's just your comment reminded me to post both these things:    1) As a result of the comment above highlighting t

Maybe just another point here that the Ratings Data might not tell the full story about this either. Truthfully we had ONE Grip Genie 5 at 126 and then I think the next lowest is something like 138. S

I'll be taking the final calibrations of my grippers later on, so I'll leave exact decimal-weight off for now, but the realistic calibrations of them now is:

HG100, before remount (1/2"...I know, disgusting) - 38lb

HG100, after remount (-3/32") - 48lb

HG150 - 55lb

HG200 - 82lb

Hard HG250, before remount (3/8") - 116.5lb

Hard HG250, after remount (-3/32") - 125lb

Hard HG300 - >159lb*

HG350 - 166lb

BBE - 172lb

To be calibrated:

* 159lb brought the handles about 1/8" apart. Didn't have the smaller weights around to get it exact.

Dad's easy HG300: 140

Is 140 lb. considered easy for an HG300? I would have thought the average was lower that.

I'm not sure what the average 300 is, but I guess I was just comparing it to my 300 that calibrated to 156.5.

I'm sure there are 300's out there that are less than 140.

Like mine. I doubt it would hit 100lbs.

I always thought my HG300 was a hard one, but now that I think of it I don't know why. Mine isn't calibrated, but I imagine it's under 140.

Magnus... did I read the HG100 right? How does a hand grip have a half inch spread?!! lol

Lol, it was a 1/2" mount, not spread. The mount is the distance between the spring and the handle, like this. And in any case, it's still really crappy :laugh

Although, at 2-1/8", the spread isn't glorious either ;)

Did a couple more tonight:

Filed #2 = 115

HG300 = 117

So, it broke 100lbs, but not by much :D

Okay, after almost 4 months, and 136 posts, I combed through everything on this thread relating to IronMind Number 3 grippers, and this is what I found:

1. There appeared to be 31 different Number 3's discussed. Some of them are listed multiple times, as some have been calibrated by more than one person.

2. One of the Number 3's that was definitely a "mutant", rated over 190 pounds, is, as pointed out in posts numbers 115, 116, and 117, an old steel handed gripper, so it is not exactly in the spirit of calibrating recent purchases, which may not be the purpose of this thread, but is a factor for me to consider what is being produced these days.

3. The other gripper with a relatively high calibration (165) appeared to drop down to 153 after being oiled (post number 70).

4. That leaves 29 Number 3's, which, rounded to the nearest pound, break down as follows:

1@142

1@143

1@144

2@145

2@147

1@148

2@149

2@150

4@151

5@152

2@153

1@154

1@155

2@156

1@159

1@161

My "hard 3" was calibrated by one person as 158, and another at 159. I listed it as 159. For Certification purposes, I was always afraid that there was a 20% chance of getting a "mutant Number 3". Obviously, based on this data, those odds are WAY off. That being said, I was at a Weightlifting contest yesterday in Los Altos California yesterday, and there was a fellow there selling House of Pain apparel, he had some IronMind grippers for sale, as well as samples of all the strengths available for squeezing. He had a Number 3 that WAS a mutant, as it was significantly tougher than my 158/159 pound gripper.

The biggest surprise is that there are as many as there are UNDER 150 pounds. Most of us are paranoid of the "mighty 3s of today". Looks to be a myth, not fact. Quite frankly, these numbers indicate these things have less variabilty than I had given IronMind credit for.

So, what I got out of this is that I need to dominate my Hard Number 3, and I should be ready for Certification.

Thanks everyone for your hard work weighing mailing measuring sharing the information.

Hub, another factor here that won't necessarily show in the calibration is the spread and sweep difficulty. Was the #3 you tried at that booth new?

I recently purchased a #3 and two #3.5s. All had a 3" spread.

The #3 calibrated at 154 out of the package and 150 after oil. However, using as deep a set as I can, it feels like a high 150-s gripper. The reason is the 3" spread and the sweep is brutal.

On the other hand, if I put that same gripper in a 20mm choker, I can kill it easily. Then it feels like the 150 calibration.

I guess my point is that if you're not practicing with one of these 3" spread grippers, you might be a bit off for that reason.

Great post Mike; I love reading all the data. I'd like to see how many were single stamps, double stamps, engraved handles, and the almight GR8 springs. I'm of the "grippers vary" school of thought but it would be neat to see how many of each there were (not asking you to dig it up).

With the data you provided the average #3 is 150.7 pounds.

We don't have all the facts as to when the different grippers were purchased. It is possible that I missed a gripper or two, but I think I got them all.

Something else I had not thought of until now. The measurements are at the mercy of the plates. I would imagine that most of the guys with the calibrator are pretty meticulous in that department. Me on the other hand, I thought I had a 5 pound PR in the Rolling Thunder the other day, but then I remembered years ago I was counting a 45 pound plate as 45 pounds when as it turned out it weighed 49!

So, are we "calibrating" without using calibrated plates? Probably, but again, I imagine that most of the guys doing this are fairly sophisticated and would not be doing what I did with my RT numbers.

I think that most of the grippers that have been put forward are relatively new, but there were a number a single stamped mentioned.

And Cannon, maybe the 3 I tried, well, I was not warmed up, I did not chalk, and those things would impact how I did on it. It very well just been 158/159/160 and not a "mutant".

Sorry to keep adding footnotes...

ae_yogi below said that it (the pool of 3s) averaged to 150.7.

In December 2006, Dave Morton (or was it an associate of his) on the Gripperhell blog said they calibrated 25 3s, the low was 138, and the high was 162.5. The average, they stated, was 150.

These results are strikingly similar.

Again, the relevance to me is that it tells me where I need to be before I say I am ready for Certification. There is some comfort that it does not feel like a set of moving goal posts to me.

My plates are calibrated, loading pin and everything. I think my gripper calibrating days are done though for now.

I have calibrated 3 of the grade 8 #3's. Two of them were 150ish. I have felt one that was a ton easier. Mike's was a ton harder. I think they are still all over the place.

I have another 350 that's even tougher at 190lb's! The sweep is tough the whole way through. Brutal.

what does a 3.5 calibrate at, 185 lb? seems like my HG's lined up exactly on 2, 3, and 3.5

I bought it off ebay as a set of the 3 in aug or sept, so its pretty new.

Usually about 182. It seems HGs have been lining up with the CoCs better, lately.
