My sidebender is very simple and reliable. It is just a piece of 14 guage sheet steel, bent to a 3-inch radius with a silicon heater blanket glued to the inside with hi temp RTV automotive gasket material	The piece welded to the back provides a right angle reference. I just plug it in and the heater blanket gives me 400 degrees F without any rheostat Back to machines Back to SHOP TOUR
