Tommy-
I bought one of the HF tubing rollers. The projects needing the radiused materials have been in gestation for as long as Blue Whale takes to bear it's young and I just couldn't stand the waiting so I bought one. Heck, for $169 on sale I wasn't going to go broke. Brought it home prepared to do some serious damage to it. Fooled around with a couple of pieces of 3/4" sched 40, got a technique going to keep things in plane [18" pipe wrench and the hairy eyeball real high tech] and then slapped in some 10' pieces of 1 1/2" sched 40. Rolled it to a 40' radius which is smaller than the radii I need. Did the job, and I thought I might be on to something, but the unit I purchased didn't have keyways just some real cheapo low grade set bolts about 3/16" that just got their guts torn out including the threads on the dies. Oh well. I bought it break it. Have plans to ream the dies and the turning shaft out and drill it through for some pins. Also had to shim the dies up into alignment so they stay parallel casue it helped keep things in plane. Not a loss at al really, I plan to use it for these jobs. Can't see going through the headache of laying out templates for the radii, especially cause I'll have no idea what the contractor is actually going to give me- could be plus/minus 6" for all I'll know, so I'll mount the HF roller on the back of the truck and use 1/2" conduit onsite to roll and match whatever it is I get for curves. Used the 3/4" in HF dies on some conduit over the weekend and it's gonna work. BTW- the Stone Age got a bad rap. We don't give Cavemen near enough credit IMO. BTW. I've got a manual pipe/tube notcher from Lowbucks laying around I need to put up for sale- it's a bit of a bear and I was never impressed with the notches it does, but would work for cattle field fence I imagine. Has the dies- 1" 1.25", 1.5". Takes a good length lever and some strongarm but might beat a torch or grinder, but not by much. Anywa, whatever it is your using for tools, the hand that's working them sure does some nice work.
