Had to grind off tack welds at front of upper longerons to adjust the shape of the nose. They were teeny welds, as I knew I would have to do this. Trying to hold/clamp the various pieces into place was a bit challenging. The geometry sort of prevented any great way to clamp, but I got it worked out. The longerons thus freed, are drawn together at sta 0, the firewall. Tacked in place.

temp tube on spine just to see what it looks like.
