Secure in the vice, preload, and hammer downwards to create two parts simultaneously. That approach will not work so well for longerons F-1013-L and F-1013-R since they are two different lengths. Plus, it seems to me the Orndorff method just makes the work twice as hard since you are attempting to beat two angles into submission simultaneously. (It does, however, tend to keep the angle in one plane while Van's suggested method does not.)...
There's no hammering involved in Orndorff's method, just body weight over a slightly open vise. my wife held one side down, and I leaned on the other. It was surprisingly easy, and cost $0.00 using clamps, a vise, and a wife I already had.
