I have one of the HF pipe benders also. Not precision, but you can make decent bends. BUT don't think you can bend TUBE in the pipe bender. Tube is OD measured and pipe is ID measured. There are tricks (wet sand, etc.) that will make some tube bends in a pipe bender, but you really need a quality set of dies and a real tube bender for good roll bar type bends. Check my project page below. The front bumber is pipe the roll bar and rocker guards are tube.
