Today I began forming the longeron curves. I brought the template with me to work yesterday, glued it to a piece of alu sheet, and cut along the line. This sheet will work as a guide when forming the curves.

It went a lot easier than I had anticipated.\u00a0 I made marks at every \u00bd inch, then I clamped the longeron in the vise, and began forming. It is done by pulling the free end to establish a small pre-load, then giving it a whack with a rubber or fiber hammer. Then you move the longeron to the next mark and repeat. I found the best way was to check with the guide every 2 inches or so, and readjusting as necessary to get a perfect fit, before continuing. As you form the horizontal curve, the longeron will tend to bend down as well. This is corrected by rotating the longeron 90\u00b0 in the vise, then straightening by hand using a steel ruler as guide.

First longeron finished, with the guide clamped in place…

Both longerons finished and clamped together. I am quite pleased with the result!! \ud83d\ude42
