Hi, I'm Jon (goofy wave thingy here) From South East Kansas, son of a mechanic, and I am a machine shop foreman. I have watched 4,782 hours of you tube on black smithing. I can prove it by the $280 worth of extra data fees last month. Built myself a brake drum forge, and charcoal retort and been playing around for a few weeks. Which equates to about a good weekends forging with my schedule. I bent some stuff, looped some rod, twisted a mess, decided I needed to make something so I got some suckered rod and fashioned out a set of tongs. They looked great, was rather proud, very symmetrical for a first try. Only took an hour. So now I need a hinge hole but I do not have a drift. I have a center punch, that'll work! So that jaw I sent flying, would that be because a center punch spreads the steel and breaks it in two pieces, or did I do something else wrong???
