Had a real productive day today. At first, I had to build an new sawhorse. Since I didn't have anyone to help me join the aft and center sections, I jumped in and did it myself. got the sawhorses positioned in place and then moved the table over to the front of the longerons. All it took was to roll the 405/405's onto the sawhorse and set the bottom skins together. Moved things around to get the baggage compartment ribs to match up to the aft section. Once I gor a few clecos in place, it went smoothly. The came the side forward skins. A little trouble getting the holes to match. Realized that I had the 405 too far into the longeron. Set it on the edge of the angle and all fit as advertised. On to the arm rests next session.
