I don't have any pix of it, but one of my favorite tube benders is an old Robinair ratcheting bender my Dad has had probably longer than I've been around. IIRC, my Grandpa on Moms side gave it to him. It doesn't do real tight bends, about 1 to 2 inch radius depending on line size, but the bends are smooth with no kinking. I also have a couple pair of the tubing bender pliers from Lisle that I've had good luck with. Those are very good for tight bends, I've bent 3/16" steel line tight enough to fit around my finger and not be kinked or have any fluid restriction.
BTW, I didn't install that one on anything, only did it to see if I could.
