When picking out a tubing bender, look for one that starts the bend on one leg. The Mittler Bros. bender starts in the middle of the bend, so you have to buy their computer bend program or be good at calculating a radius length. Make sure you buy a tubing bender...not a pipe bender. I use a #2 Hossfeld bender. You can get a manual one thru Williams Lowbuck Tools (
www.lowbucktools.com). I powered mine with a cable puller for several years before powering it with hydraulics.
Be very careful operating an bender, there is great forces at work...you can get hurt!!!
Just my experience of 30 years of running a chassis shop and being thrifty,
