I was making great progress on my SB fuselage.... longerons curved to within 1/16" of an inch compared to the template, side skins rolled to ~60 degrees.
Everything seemed great until I clecoed it all together, and I am having some alignment issues on both sides of the fuselage.
I twisted the F-1041 channels until they were parallel with F-1042 on the aft end and the WD-1003 weldment at the front. Before I clecoed on the skins, I used a sharpie to draw a line where the F-1042 wraps around the WD-1003.
After a bit of wrestling, I got the forward side-skin all clecoed on. The curve (as seen below) matches the firewall, and the underside edge of the skin buts nicely to the floor skin.
However, when I started to look at the F-1041, it appears that clecoing it to the skin caused it to shift outward from the WD-1003 weldment. Additionally, you can see where the floor pan is to be riveted to the F-1041, there would be huge edge distance issues if I tried to drill it as is.
So here I am looking for suggestions as to how to get this all to align better.
