Ring Bender

I wanted to make my own Jewlery with old cutlery. I therefore designed this Ring Bender. Works fine, but i have not been able to try it on any cutlery as i realised i didnt have any to test on. I have therefore only tested it on small nails and such. It works exaclty as expected; solid and strong. I have not had any issues regarding the strength. You will need; 3 M5 heated inserts. 1 M4 heated insert. 4 M4 bolts (3 the same length, 1 smaller) 2 M5 bolts Long 1 M5 bolt short. 3 M4 nuts.
