Default 3.5" TUBING bender (update)

I posted a few weeks ago asking if anyone knew of a place that could custom bend 3.5" tubing. Pretty much all of the responses were that I'd have to cut and weld standard bends to get the angle I wanted.

Well, I found a place that could do 3.5" (and larger) mandrel bending... and for pretty cheap too. They could also do tube end beading for hose attachement, but I wasn't sure if the exact length of tubing that I'd need, so I just had them bend it and send me a longer peice.

Thought I'd pass along the info in case anyone needed it.

Default I don't know the exact process, but basically it means bending a pipe/tube without...

decreasing the inner diameter at the bend (so flow isn't restricted).

Default No one suggested them to me when I posted before.

NJ isn't exactly local for me anyway.
