austinslater Posted January 8, 2003 Share Posted January 8, 2003 I just got my grippers from John at pda, 280 and 295. They both are harder then my 2 and easier then my 3 although the 295 is pretty close to the 3. This should help me on my way to the 3. How does everyone else compare? ALso the 280 said 502 on the handle, is this the IP? Thanks guys Quote Link to comment Share on other sites More sharing options...
amaury Posted January 8, 2003 Share Posted January 8, 2003 If 502 was to be the IP, your 280 would be closer to a #4 than to your #2 . Check the "Calibration Results" thread pinned above... Amaury. Quote Link to comment Share on other sites More sharing options...
Bearcat 74 Posted January 8, 2003 Share Posted January 8, 2003 I wouldn't worry about the #'s, I think it's been proved they mean jack. If you can close them, close them. If not work harder until you can. Quote Link to comment Share on other sites More sharing options...
Griparn Posted January 8, 2003 Share Posted January 8, 2003 I just got a new #3 and it's easier than my old #3, unseasoned. Quote Link to comment Share on other sites More sharing options...
Tou Posted January 8, 2003 Share Posted January 8, 2003 Ihave a 309 that is about the strength of a #2 and a 325 that is very close to my #3, and my #3 is A LOT tougher than any #2 I've tried. Quote Link to comment Share on other sites More sharing options...
amaury Posted January 8, 2003 Share Posted January 8, 2003 Ok i know the IP @ closure is not at all a precise indication of the difficulty to close a gripper but who has heard of a #2 (or even a #3) beyond the 500IP range... I think it would be going too far to say that IP isn't at all an indication of the difficulty of a gripper. According to the PDA Calibration thread: #1: from 182IP to 254IP @ CL #2: from 263IP to 307IP @ CL #3: from 359IP to 452IP @ CL #4: from 522IP to 587IP @ CL Conclusion: among the grippers of the board PDA tested there's no #1 with a higher IP @Cl than a #2, no #2 with a higher IP @Cl than a #3 and no #3 with a higher IP @Cl than a #4. IP @ CL is not a "complete" non-sense... Quote Link to comment Share on other sites More sharing options...
Adam Black Posted January 8, 2003 Share Posted January 8, 2003 Austin, I too recently bought a PDA 280 & 295. I find that my 280 is harder than my IM 2 and is easier than my IM 3. Last time I made an attempt at the 295, I was farther from closing it than I was my #3. I am very close to closing my 3, but have not tried the 295 since I got it. I will give it a go again tonight and see if I can close it. My 2 PDA grippers have some large numbers on them as well. As far as the numbers go, I believe that PDA was working on a new rating system, but discerned that any rating system was inaccurate and thus discontinued that effort. I think those large numbers are a remnant of that new, yet discontinued system. Quote Link to comment Share on other sites More sharing options...
Roark Posted January 8, 2003 Share Posted January 8, 2003 Amaury, The difference between the 1 and 2 in that list is 9 IP- an excellent training step in terms of resistance, but confusing in terms of comparing strength. Whoever could close that 1 could probably close that 2- an evident fact if they are side by side and available. But if you own the 1 and I own own the 2, and we chat about it here, a whole new perception arises- that is, that I am an entire step ahead of you, when in fact I probably am not. If those 9 IP dissolved, then your conclusion would not be valid. I say again, comparing strength on the same brand of gripper machines will yield meaningful comparisons.

KJM Posted January 8, 2003 Share Posted January 8, 2003 FWIW My 280 is easier than my 3. My 295 is harder than my 3 Quote Link to comment Share on other sites More sharing options...
supersqueeze Posted January 8, 2003 Share Posted January 8, 2003 502 is probably a manufacture DATE. Mine have both IP # on one handle and date on the other. In my case the date is 1201. Mike M. Quote Link to comment Share on other sites More sharing options...
AnimalCage Posted January 8, 2003 Share Posted January 8, 2003 I have PDA 1201 stamped on one handle, and 343 stamped on the other. I'll go with the Date theory. Quote Link to comment Share on other sites More sharing options...
Guest Mikael Siversson Posted January 8, 2003 Share Posted January 8, 2003 IP @ CL is not a "complete" non-sense... No, but pretty close. I recently had the opportunity to compare a PDA 437 ip and a PDA 520 ip. They look almost identical and they feel almost identical. The 520 ip is nowhere near a #4 in difficulty. If you could just close the 437 you would have 1-2 mm left on the 520. There would definitely be the odd #3 out there harder than the PDA 520.
