I tried my best to keep all of them between 2-4 pound jumps. Now I need to do the same between 154-182. Luckily I already have a Megalodon and unrated RB300 that may fall in that range. Time to ask around and to get some more rated. Quote Link to comment Share on other sites More sharing options...

DW85 Posted August 20, 2015 Share Posted August 20, 2015 Figured i'll throw my hat in the ring...All were rated using the digital crane scale method on a rig I built recently..All Springs were clean and oiled followed by a few dozen chest crushes before rating...A couple of them were rated by Cannon Power Works which i checked against my own ratings to see how accurate my setup was at this point...Might build a revised version in the near future...My collection thus far: 2004 Mfg. IM COC 1 (non COC stamped, black spring) - 79 2004 Mfg. IM COC 2 (non COC stamped,black spring) - 109 IM COC 2.5 - 125 GHP 6 - 126 BBSM - 127 (CPW=127) IM COC 2.5 - 130 GHP 6 - 131 BBSM - 136 BBSM - 137 IM COC 3 - 145 BBGM - 147 IM COC 3 - 148 IM COC 3 - 152 CPW Spectrum RB 300N - 153 (CPW=154) 2004 Mfg.

AryanVegetarian Posted September 19, 2015 Share Posted September 19, 2015 (edited) I'm new here so apologies if this is in a FAQ somewhere. From the little reading I've done, IM spring manufacturing/calibration has become more accurate over time and grippers vary far less than they used to. Reading RGC ratings here, I'm not sure whether poundage variance is simply because they're old models or if the upper/lower bounds still hold true. Is there any data on gripper variance for those produced in 2014/2015? (or whenever they started producing the latest variants).

Yes, here: http://cannonpowerworks.com/pages/grip-strength-ratings-data Those ratings are for all new grippers out of the package and only 2012 through present. IronMind has not changed their "recipe" in that timeframe as far as I know (same GR8 springs the whole time is what I mean). That should give you an indication of how the grippers vary as it relates to the Rating Service. Remember there are variables to the Rating Service as well and it only measures 1 thing about the gripper. But, your question was about ratings after all, so I feel the chart is applicable. 1 Quote Link to comment Share on other sites More sharing options...

That's exactly what I was looking for. Do you have any info on standard deviation/spread of the data? It would be interesting to know what the percentiles are. E.g. for the 3, can we say there's a 95% chance a new gripper will be between X and Y. It's hard to know how rare the outliers are just looking at min/max.

From the provided data you can figure it out. I highly highly doubt cannon documents every gripper calibrated. That would take too much time. And as for the second part, can you tell me that there is a 95% chance the used car you bought will spin a rod? Or the new TV from best buy will have a cracked screen? No, this is a question that can't be answered. This is a wait and see kind of thing. You have to remember when dealing with steel it will all vary based on what else is being smelted and the end forging process. Hell maybe your gripper was made on a Friday and a worker skipped a step or the steel wasn't at temp and that's why a 3 could rate at 138lbs vs 150lbs Quote Link to comment Share on other sites More sharing options...
