This is a remix of 5469915 that looked interesting, I have not tried this type of grip before, so I thought I would give it a go. I made some modifications to it to better suit my hand, I also modified it to accept my previously designed bands clamps (see 6554446)
The clamps btw are set up for 1" 12-24 bolts/nuts
