I too think its a two man job!
However, BS'ing around the supply house I heard about this gem.... (I have not tried it, but will next time a real op arises for lots of it.) 10,000Lbs ratheting cargo strap, and 2 vise grips! This guy was telling me about, and says he's been doing it for years? Lock one vise grip to the bender, and the other to the pipe so the strap wont slide, and crank up the strap. Disclaimer, not sure how well it would work, but sounds like it would.
