For the actual bending we used a JMR hydraulic bender. This piece can be outfitted with many dies, and has a degree ring and pointer to show what angle the tubing is bent to. Be sure to first determine how much spring back your tubing has. Spring back is the number of degrees (our DOM had about 5) that the tubing must be bent past the desired angle in order to get that angle of bend. For example, the tube had to be wrapped to 48 degrees in order to get a 43-degree angle once removed from the bender.
