Tried using a regular claw hammer to set a hot punch and it went about as well as you'd think
I was working on a leaf keychain last week and my punch kept slipping. My good ball peen was across the shop, so I grabbed a cheap hardware store claw hammer thinking 'a hammer is a hammer, right?' Wrong. The first hit glanced off and sent the hot punch flying into a bucket of water with a huge hiss. The second try, the hammer's face was so soft it left a dent in the punch. Switched back to my 2 lb ball peen and it set perfectly on the first tap. The difference was all in the hard, polished face versus that soft, rough one. Anyone else have a 'wrong tool' story that went hilariously bad?
My old framing hammer has a face like a waffle iron, so I learned wyatt_green's lesson the hard way trying to set a center punch. It just skidded off and put a nasty gouge in the workpiece. I keep a cheap little engineer's hammer with a smooth face at the bench now just for punch work. That one change made all the difference, no more chasing tools across the shop.
That's the whole "right tool for the job" thing in a nutshell. You see it everywhere, people trying to make a cheap version work and it just makes more of a mess.
