The harbor freight bender works OK on thick wall pipe such as .125 wall 1" and heavier wall 1 1/2" and 2". I have even used it to do some small(nothing greater than about 30 degree) bends on 1" .125 wall box tube to make a spray tank trailer frame and arched rails which also worked OK. Anything thinwall is going to wrinkle the skin on the inside of the bend radius as the dies are not a tollerance fit to support the sides of the tube and force the stretch/compression of the inner and outer radius sidewalls that are required for a smooth bend. I was going to experiment with a tube packed with sand, but havn't got around to it.
