A little pic I just took. The second pic shows that I had to weld a piece of 3/8" pipe to the back of it to give it some structural support while rolling the IC pipes. Otherwise, the frame twisted, and I couldn't get the pipes to roll.
I'd be interested to know if your DIY roller works. I agree that it may take some extra oomph to get it rolling with a strap wrench though. I have an 18" handle on mine that I have to really crank on to get the bead going.
