Not sure why people are having so many issues with this bender. It worked great for me. A few tips is to grease EVERYTHING. Every pivot, every threaded part grease the hell out of it. My guess is the majority of people didn't do these and that's why they are having trouble. I also tightened the bolt that holds the ring on that holds the tube in place. Not sure if it helped or not but seemed like a good idea. this will need to be bolted down. I tried just hold it in my vice at first but the vise would spin on its base. I bent up four of the parts in my pictures with no issues at all. Material was 3/4" OD x 1/16" wall steel tubing.
