Bending tube isn't cheaply done. Especially large diameter thin wall tubing like what we want for vanagon bumpers. You definitely need a mandrel bender which costs tens of thousands of dollars. And no, muffler tube benders do not work. You need a mandrel inside the tube to keep the walls from collasping. The bends need to be a tight radius and the wall thickness needs to be thin to keep the weight reasonable. The Harbor Freight/Princess Auto benders are for heavy wall schedule pipe only, gas pipe. I wonder how many people buy them thinking they can make exhaust systems and roll bars. You can't even make handrails with them. I don't know what people use them for. Further, the dies are sized for pipe, not tubing. Gary Lee
