That's a pipe bender, not a tube bender. You can make it work, but it is a lot of work. That particular bender the included dies are different OD's than using tube. It's been awhile, but if I remember correctly, if bending 2" OD tube, you would have to use something like a 2.25" OD die. Those benders make a pretty nasty flat bend at the outside of the bend as the press will try to fold the tube instead of bending it, then the two outer rollers put some pretty nasty dents in the tube as well. Some guys get it to work OK for roll cages and things that they don't care about looks, by filling the tubing with sand, capping the ends, then bending. I tried them a long time ago before I got smart, and they are a waste of money. The ProTools bender is about $6-700 with one die if you look in the right place, and make some nice work. I highly recommend the ProTools bender. Paying someone to bend the tubing is more expensive that getting a proper bender, and you will scrap a lot of tube or be real unhappy with the end product if you go cheap with the pipe bender. And, IMHO, a flattened bend from using the pipe bender instead of an even rounding radius bend from a proper bender is not as safe. If making something that is supposed to protect you in the event of a rollover, you don't want any possibly fail points. Save some more money, get the proper bender, sell it when you are done. You will get most of your money back in the sale if you only use it for one cage, whereas you won't get squat in resale with a pipe bender.

I finally found the tube bender I was tryng to tell you about.
