I have a project that is going to need a large radius bend. What sort of rigs do folks use?
I looked around a little, and I see equipment for bending up roll cages and what not: 3rd Gen Hydraulic Round Tubing Bender & 1 Die Set (speedwaymotors.com)
This young man has developed a nice tool, specifically for bicycle work. The ability to bend two 5/8" or 3/4" tubes side by side is a nice feature, but the price tag is a bit, ... ouch! The Cobra Tube Bender for Bicycle Framebuilding - YouTube

I have a collection of conduit benders and hickeys in different sizes.
The issue with any of these rigs, is that they bend to a fixed, relatively small radius. I'd like to form a much larger radius. I was thinking of improvising a roller rig, with some polyurethane rollers I have lying around, that I could machine to a profile suited to the tube OD.

What advice does the forum have for forming large radius bends?
