Wider spring = Higher RGC?

As already discussed. Feeling and actually rating is not the same thing. Decrease the spread from 80 mm to 25 mm and the same rating are two different worlds. Same with knurling, put on some handles with shiny handles without knurling and you will lose a lot of closing power.

True, that’s why I have to get it rated because it’s not facts to go by feel.. nonetheless, mostly for fun tbh

You don't need the facts. RGC system is not perfect. It's just one way of estimating how hard a gripper is. You body and brain doesn't care if it says "156" or "160" on a machine. It's how hard the gripper actually is to close that matters.

That's why I don't think it's good practice to use a bunch of different grippers when competing in grippers. It's better to use the same gripper, which you can adjust the levels on.

Like the Vulcan for example, love that thingThank you!

Yes the vulcan is a beast, so damn hard to set as well.

I think silarukov actually made a gripper where you could adjust the resistance but not only that, you could also adjust the spread of the handles if I'm not mistaken. I have never tried it though. Seems like a really interesting idea.

Oh yeah the set is insanely hard on the Vulcan

Really?

I need to check that out, Silarukov still having that?

Rare indeed, and again I only assume it’s around that based on my experience with other grippers, feel and information I’ve got

Do you have any rated grippers? Because it's hard to gauge anything, if you don't have any rated grippers.

I gauged it based on my (assumed) average #3, pretty much it.. going by the CPW table of ratings..

I’ll make sure to rate all of them since I’ll be getting myself an RGC device, and I’ll definitely apply the advice @Cannon said “rating the same gripper atleast 5 times” to get a decent accuracy..

For me it’s just a fun thing but also interesting to see what you’re actually closing.

I’ll rate all my grippers when I get it, any further rating advice is welcome btw.

@C8Myotome went through hell getting his to rate accurately to previously rated grippers.  He can probably chime in.

You'll need a CPW rated gripper to calibrate to if you're basing your assumptions off of the table of ratings @Cannon has on his website.  Otherwise your effort will be a self-fulfilling prophecy, changing variables until it hits the number or falls into the range you have in your mind.

Definitely agree with this. It's one of the big reasons I bought some rated grippers from Cannon, basically to calibrate my homemade rating device. Now I can actually compare and look at the CPW rating chart, to see where my grippers are at in comparison. I was disappointed with my original #3, I was of course hoping it would be above average but it turned out to be 144 so a bit low but that's how it goes.

Well, Silarukov has various adjustable grippers, but I think you are talking about the эспандер Муравей (expander Muravey). You can adjust the settings. There are other adjustable to train the pinch, the эспандер Тиски (expander Tiski) (link). I was interested in them but the ongoing war...

Ugh man this sucks with the war and stuff, for other reasons than this but this aswell

Thank you for the link tho

Really don't know why you write with cyrillic.

Here's the gripper: https://mrstronghands.com/silarukov-3-adjustable-hand-gripper

Took a look at my super heavy #3 with an RGC of 160-165, and the width was exactly 80mm/ 3.15 inches..

That’s a pretty average #3 spread. I think you’ve mentioned before your #3 is not actually rated. 160+ is exceptionally rare. Like white whale rare. I think you might be wrong about the rating if you’re just guessing. Remind me what you’re basing the number on?

 

I miss a point that I found in the comments of this video: @Ryroza 

That "distribution of energy" can explain why some grippers feel harder than others but with similar RGCs.
