Straightening canopy latch angles

Jo was over again today and helped me cut and drill these canopy latch angles. We also found that the angle wasn't 90 degrees, which seems to be a common problem with aluminum extrusion. He helped me spread the angle open a bit so they're 90 degrees. In the process, I was able to give him a primer on stress strain curves and such things as the elastic and plastic regions, among other things.
