OldGuy Posted March 17, 2004 Share Posted March 17, 2004 Copied from a Zcor post Received a couple of grippers from Warren Tetting today and with the grippers came a letter announcing his new trademark stamp to denote their strengths. (grippers renamed using the alphabet) As follows using the Alphabet for strengths and COC parallel: Beginner--A wiresize .225 COC T Advance-- B wiresize .235 COC #1 Super Advance--C wiresize .250 Master--D wiresize .260 COC #2 SuperMaster--E wiresize .273 GrandMaster--F wiresize .281 COC #3 Elite--G wiresize .291 SuperElite--H wiresize .306 GrandElite--I wiresize .312 COC #4 Pro--J wiresize .331 WorldClass--K wiresize .345 Quote Link to comment Share on other sites More sharing options...
JeffPeterson Posted March 17, 2004 Share Posted March 17, 2004 I don't know about a couple of those wire sizes. i was there the other day and he and I checked some of the elites and they were around .295. Oh well. Quote Link to comment Share on other sites More sharing options...
OldGuy Posted March 17, 2004 Author Share Posted March 17, 2004 My Elite is 295. I Mic all my grippers and go by wiresize before anything else. Quote Link to comment Share on other sites More sharing options...
JeffPeterson Posted March 17, 2004 Share Posted March 17, 2004 I try to do this as well. It's the way to go. Quote Link to comment Share on other sites More sharing options...
Rick Browne Posted March 17, 2004 Share Posted March 17, 2004 I don't know about a couple of those wire sizes. i was there the other day and he and I checked some of the elites and they were around .295. Oh well. I have discussed this issue with Warren concerning variances among grippers. Springwire comes in spools of 1500 to 2000 feet in length. For example, you can have a spool of springwire labeled .291 and using a micrometer, take spot measurements along the length of the spool, lets say every 18 inches or so. You can be assured you will find thickness variances by as much as .2000 of an inch. This factor is a given in the steel industry that produces said wire. They are granted this variance in procressing and manufacture. However, this variance would not be accepted in wire that would go into NASAs Spaceshuttle. Another factor in springwire variances will occur during the gradual heating process the springcoils are submitted to. After the springcoil is made, maybe a hundred will go into an oven and slowly heated to 300 degrees for 2 hours then slowly over 2 hours the heating process is reversed in the oven for a cool down. The actual placement of the springs in the oven will have a determining factor to the strength of the coil. Some coils will receive less of the proper heating process by being in a certain spot in the oven. This process is what makes the springcoil able to do its' function Quote Link to comment Share on other sites More sharing options...
OldGuy Posted March 17, 2004 Author Share Posted March 17, 2004 Maybe grippers should be gauged with a mic before being sold. For example BBE .293 BBE .295. Whatever they are rather than the nominal wiresize. Quote Link to comment Share on other sites More sharing options...
Rick Browne Posted March 17, 2004 Share Posted March 17, 2004 (edited) Maybe grippers should be gauged with a mic before being sold. For example BBE .293 BBE .295. Whatever they are rather than the nominal wiresize. I agree, and maybe add a label stating the wiresize to the buyer..... "Oh you want an Elite?"... Well lets' see, I have 3 for sale"... "One is .291, one is .293, and one is .295". "What's your flavor?" As a matter of fact, Tetting told me that in the future he will be stamping the wiresize on the handle Edited March 18, 2004 by zcor Quote Link to comment Share on other sites More sharing options...
OldGuy Posted March 18, 2004 Author Share Posted March 18, 2004 Those few thousandths make a difference. Quote Link to comment Share on other sites More sharing options...
JeffPeterson Posted March 18, 2004 Share Posted March 18, 2004 I'm always surprised at how a few thousandths make a huge differance. Every time I move up to the next gripper I'm reminded. Quote Link to comment Share on other sites More sharing options...
Rekx Posted March 18, 2004 Share Posted March 18, 2004 OK...Noob question here... Is this list of grippers the same list as the Beefbuilders on the WeighliftersWarehouse page? Curious because I just placed an order for a Grandmaster whish is listed as 220lbs of pressure on the WLiftersWarehouse, but on the list above the Grandmaster is listed as equal to the #3, which would be 280lbs of pressure.

MIKE HALEY RILEY CLOE Posted March 18, 2004 Share Posted March 18, 2004 Trust me, the GM is equal to or harder than a #3. Go by the wire size, I have no idea how WLW came up with those numbers. Old guys copy of Zcors post at the top of this thread is very accurate. Mike Quote Link to comment Share on other sites More sharing options...
Matt76 Posted March 18, 2004 Share Posted March 18, 2004 it says there is a bigger jump from the #1-2 then there is from the 2-3. Well as far as wire size goes it sure doesn't feel like it Quote Link to comment Share on other sites More sharing options...

A given rating depends on where the test load is placed on the gripper. As I understand it Ironmind gets their rating by placing the test load at the center of the handle. The test load being closer to the spring, causes a shorter leverage use of the handle therefore using more weight to close the handle. BeefBuilder placed the test load on the end of the handle, therefore less weight is needed to close the handle due to full leverage use of the handle. I am sure it is more complicated than I just wrote, but basically that is why the difference in given ratings Quote Link to comment Share on other sites More sharing options...
Tom Black Posted March 20, 2004 Share Posted March 20, 2004 Yet another labeling system (consecutive letters)! IM doesn't have trademarks on numbers, he could have done "T1, "T2" or something like that, one letter/number on each handle. I really wish someone would just go by wire size, the 225, 235, 250, etc. Quote Link to comment Share on other sites More sharing options...
OldGuy Posted March 20, 2004 Author Share Posted March 20, 2004 I think it too late to sort out the Tetting gripper labeling mess. At least it helps to cover up gripper variances! Quote Link to comment Share on other sites More sharing options...
Matt Van Weele Posted March 20, 2004 Share Posted March 20, 2004 He told Strossen he would not use the numbers while back. The reason they were changed again is because someone else though up the names for some of the grippers and wanted money for each gripper Warren sold that wasn't through this particular guys company.

OldGuy Posted March 20, 2004 Author Share Posted March 20, 2004 The past confusion cannot be helped. It will be good to start over with known wiresize, and ignore whatever fancy names the grippers have, many of them confusingly similar.

Matt Van Weele Posted March 20, 2004 Share Posted March 20, 2004 Good suggestion Erik. He is open to ideas superior to his or at least ideas people think are superior to his. I think the best idea would have been to have all companys just stamp the wire size on the handles. The wire is biggest factor in determining the strength.

Matt Van Weele Posted March 21, 2004 Share Posted March 21, 2004 Probably .002. If it was .2 that would mean that there were Beginners or Ironmind trainers running around stronger than #4's. Quote Link to comment Share on other sites More sharing options...

Yeah, should have just wrote 0 twothousandths of an inch like it was intended or .002 .
