matek Posted May 13 Share Posted May 13 (edited) This project started with me wanting an "ultimate choker gripper"; basically a hybrid between Standard adjustables and the CPW/Aaron Corcorran style choker grippers. Although the huge washer solution works really well on the adjustables, the biggest downside is that choking at the spring is suboptimal compared to choking at the end of the handles. So I thought, why not design a gripper based on Standards (my favorite gripper line). I learned about torsion springs, including how to measure things and materials, and made the specification. I found a local company that makes springs for machines, old toys, etc., and they could make the spring I wanted. The handle was more problematic. Not even because of the tapping but because of the knurling. I wanted the handles to be stainless steel with nice knurling like on Standards or GHPs. Thankfully, @Cannon gave me some really useful pointers (thanks again, Matt), so I made the design and ordered the handle from the company I usually buy steel for bending. I wanted at least six levels, ended up with seven including Flush. The levels are laser engraved into the spring. I didn't want to cut the spring, so this seemed like the best solution. Getting the hardware for the choker mechanism wasn't a big deal. I've MMSd some of the easier Levels, and well, it is one hard gripper that's for sure. Even those easier settings are far from beginner level. Btw I don't plan to make this again, it's a nice one-of-a-kind gripper. Only one thing remains: sending the gripper to CPW for rating! Some general stats: Spread: Flush - 70.5mm, Level 6 - 83mm Spring: 8.0mm diameter (slightly thicker than a Tungsten), oil-tempered steel Handle: ~19.4mm diameter (same as Standard because of the aggressive knurling), 304 stainless steel Weight: 521g/1.15lb (for comparison, my CoC #3.5 is 261g/0.58lb) Choker: M6 stainless 304 Some pictures: First one is at Flush Second is Level 1 Third and fourth are showing the choker at Level 3 Fifth pic: the whole "kit" @EmilBB this is the project I was talking about Edited May 13 by matek 19 Quote Link to comment Share on other sites More sharing options...

EmilBB Posted May 13 Share Posted May 13 That looks so amazing man, such a great idea. I'm curious what CPW is gonna rate those different levels, with that huge spring at 83mm spread it must be up there. 2 1 Quote Link to comment Share on other sites More sharing options...
