Cheapest place for torsion bar removal tool/clamp?

It’s crude as hell.... but when I was young I made one out of a 2x4. I ripped it and used two U bolts from the hardware store. I clamped the hell out of it and beat the bars out. Actually came out pretty easy. The Wood didn’t put a scratch on the bars. I have seen a bar broke. Where Channel locks or whatever put a stress riser in it. It was pretty neat to see how one scratch started the break.
