These were made out of a bar of steel 3/8 thick x 3/4 wide x 24 inches long. Each jaw is 1/2 half that bar. Hours and hours and hours and lots of beating with a hammer. But they work so nice. So I guess it was all worth it. 😉 Now to make another 6 to 8 pair. Gonna use 1/2 inch coil spring for the next few pair.
