Today, I was able to construct the jig to hold the tail post in place. This is an important step as the post acts as a reference point when building the rest of the aircraft. I got everything ready to tack weld in place. I did try to smoosh the end of the longerons cold, but it was too much to try to hammer it down without screwing anything else out of alignment. I'll just bend the tips hot when I tack weld the longerons.
