I bought a heavy duty pipe bender from e-bay. £12 delivered and it's new, guy sells loads of them but I would advise a little heat as it is hard
work, unless you have arms like popeye, which I do.

A pipe bender is great but you are restricted to fixed radius bends because the radius is dictated by the former.

I'd think the pipe bender would work great for it's normal radius, plus any larger radius. Bend a little and push it along, bend again,
push along...
I mean, how perfect does it have to be? Usually "perfect" isn't needed for our cars.

I have bent 3/4" (19mm) tube with just the vice and a blowtorch with great success to make anti roll bars etc, just heat a bit and bend a bit at
a time, be gradual and controlled and its no problem.

I've just seen a guy bending half inch steel conduit with a pipe bender.
Try your local electricians, they might be able to bend larger sizes of steel tube for you

The attached picture shows bends that I made using a bending beam. There are no right and wrong ways to do things, you just find a way that works for
you. For me, the bending beam is simple cotrollable and involves no cost.

I bent the rear corners from 19mmx 1.5 by just holding a steel disk about 180mm dia and 20mm thick in the vice with one end of the tube trapped under
it against the vice. I then gradually bent it around the disk by hand without having to heat it at all and had very little distortion.Maybe a brake
disk could be used.I made two seperate bits and sleeved and welded them to the straight bit in the middle.

The anti-roll bar (grey bar in the pic below) in this pic was bent using a 4" record vice, a disposable cartridge plumbing blowtorch and my arms
and eyes and that's it.
You can do the same it's not tricky!
