I had to bend some 25x8 flat (the hard way) into a 1.5m dia ring and don't have a ring roller.
I thought about getting some one to do it but had a go myself.

I curved a bit of 25x5 in a small slip roll then stuck it to a bit of plate with a stop to hold the flat in position and a bit of scrap tacked on to try and keep it flat then welded the whole lot to the bench.
I kept the radius a bit smaller than needed to account for any spring back.
I also had to cut the steel into 10' lengths to let it swing around in the shed.
I put the end of the steel in the jig and started tugging on it but it wouldn't go........turned out the other end was hooked behind a bit of the lathe
Once unhooked it was surprising how easy it was to bend...bend a bit then push it through the jig and bend a bit more. When it got short i put a pipe over the end.
I used a 10' length and a little bit more.
It's for a table top repair and i have the original so was able to tweak the curve a bit to get it right before welding the two bits.
Once it was done i welded it to some sheet and went around it as a guide for the plasma.
The bit that was left sticking out i was able to hammer over all the way round to give a nice edge.
I clamped a bit of angle to it to prevent the sheet lifting as i hammered it over.
I had been worrying a bit about how i was going to do it for a couple of days but the jig made it easy and it only took a couple of hours.
