I clecoed on the side skins tonight and match drilled them to the F-704 and F-705 bulkheads. The plans just said to cleco the F-704H side plates to the forward and aft halves of the F-704 main spar bulkhead, but I figured if I was going to be doing match drilling, I might as well match drill through all three layers at once.

I decided that since my edge distance wasn't great for the F-623A-AFT tie plates (especially the left one), I would remake them out of .063 thick aluminum. This scrap bellcrank arm is just what the doctor ordered.

They look good. Much heavier duty than the .032 ones.
