Those types of "benders" might be OK for making farm gates, or shopping cart corrals, but nothing you'd want to build a tube chassis with, you might as well take it to a muffler shop. The JD Squared will make bends you can be proud of, almost like mandrel bends, they pull the tube around a polished die, therefore it doesn't deform the roundness of the tube, like an exhaust pipe bender does. Spend a bit more, and get something you can be proud of, and if you want, you can still make farm gates with it! Bob
