2 hardy hot cutters

[Sam Salvati]

Forged these guys up on saturday, only had a couple hours in the shop. I forged these from some 2 1/2" wide by 3/8" thick new spring drops from the spring shop. One is for the pritchel hole, I call it a 360 degree hot cut you can spin it to make end cuts, angled cuts, incise bar down it's length. Plus, if you have a special swage in the hardy hole you can have the hot cut right next to it without having to switch tooling. They both work quite well. they are a bit rough looking, I tried not to do too much grinding to them.

something neat to remember, that 360 degree hardy was about 3" of 2.5" by 3/8" stock when I started

What size is your hardy hole? I'd like to have seen a side shot of the larger hardy, I'm curious what you did to thicken that 3/8" for the shank. A faggot weld, maybe? Also, I'm surprised to see the cutting edges so curved. I'm used to straight edges on hardies and have only ever seen such. They work well, huh? I can definitely see how it would be an advantage when incising a bar, it would stay on track better.

Salem, the bottom photo is a side on shot of the larger one. My hardy hole is 1", I insert the cutter either on the diamond, or parallel and use a little wedge to lock it in. I could have drawn more out I guess then folded it over, it wouldn't even need to be welded.

a fellow I very much respect, Brian Brazeal prefers convex edges on the hardies he makes, it's a personal taste thing for some but Brian says it cuts better, and I agree having used both. It's like a veining chisel, you can make straighter cuts as you can move the bar along the edge and keep it in it's cut easier.

Right on, Sam. That's a good way of getting around having to have thick stock for hardies. Maybe I'll make one like the big one and try it out.

It's easy as could be to offset shoulders on flat bar, but quite hard to set a shoulder in Large diameter stock.

Nice ones Sam. I need to make one up soon.
