How do you all make professional bends in large tubing like 1-1/8" OD.

Virtually all tubing benders (spring and lever type) seem to top out
around 3/4",

Would something like a Greenlee EMT conduit bender work.

There are some specialty benders with custom dies but prices are sky
high.

Any suggestions on best known methods.

P.S. I realize tight bends will require fittings. I'm talking about
wider bends.

You can heat it and bend it although it will cause flaking inside,
You can use one of the expensive benders
You can cut it and use fittings
You can bend it by hand but stop just before it kinks :-)

        The trick is, you have to stake it down properly.

        The correct tool for this is, of course, a tube stake of the
needed size. So, simply insert your 1 & 1/8th inch tube stake in the
pipe, and bend.

Recommend you ream the pipe first before placing your tube steak in the pipe
