I was hoping to use a 5' pipe on one end and a vise on the other with
a 3 1/2" pipe (it has to end to be a 3 1/2" inner diameter U-bolt).
It'll be 316 grade steel for marine environment use.
Can I cold bend it? Is a 5' pipe enough leverage?
Should I heat it with a welder's propane torch as I bend it?
I did something just about like this one time when my father-in-law
wanted a stainless dinner bell. My buddy set up his Hossfeld bender
and we made the 2 bends fine, then had to tweak it slightly to get
it planar. The bends were perfect, identical radius.
I think you should buy a 3 1/2" stainless U-bolt from a trailer supply.
