They work fine for meThe Panbrake plans opened up OK, but the Bending Rolls article came without the pictures for some reason.

My thoughts too, I tried to get some stuff bent / folded a few months back in my "second" home and they'd only do aluminium. I was trying to get some steel bent for my tool box / work bench, which is still waiting to be done.
"I assume that's about contamination? Big believer in this personally if you want to specialise then specialise"
No, the machine just wouldn't bend 1.5mm steel, they were fabricating aluminium gutters and similar things out of 0.5 sheet. It was (should say they as I tried a number of shops) a full size machine, hand operated.
I eventually found a place, but the job got cocked up and as a consequence, isn't finished. Might have a go at building one. The one in Ronans' message would be more than adequate for my needs.
