I had planned to trim the front end of the J stringers when I got the front bulkhead in place, but forgot to check the front (F-706) bulkhead so had it clecoed in place before I noticed that the stringer butted against it instead of passing through like the other bulkheads. So, I had to take it back off, trim and contour the ends of the 4 stringers, and put it back in place. Then, I was able to cleco the side skins in place. Starting to look good.
The J-brace was a little long, on purpose, so I could trim it in place. Didn't work that way.
One side skin in place.
The other side skin in place. Starting to look like a fuselage!
