I would like to bend some 1/8″ wall 1.25 x 1.25 inch aluminum tubing to form a foot rail for a raft frame and I am wondering if there is any formula/theory on how tight a bend is too tight, and if I could do it with a conduit bender…..

you would be much better off to take it to a steel fab shop they have the tools and all the formulas
metal fabricating or iron works would be the best place for a mandrel bending machine. years ago they use to pack it with sand heat the tube then bend around a makeshift form... you could try that but it's a two man job at least. slainte'

The bender is $295, and the die would be about $150. You probably don't need the hydraulic assist for aluminum. Bends real easy.
