Finished the stab today.
Got the top sheeted, removed the pins/jigs and flipped it over:
Sheeting the bottom:
Cutting around the strut mounts seemed simple enough:
But I missed the 1/8" for the TE and cut the hole oversize. Also got the length wrong:
But I used the piece I cut out to add some material back in and got a decent fit:
After that the other side went much better:
It's rough sanded, but per the instructions I did not round the leading edge. FWIW, when I fit the right side, bottom sheet in and it lined up perfectly, I was so excited I yelped. Man I'm a dork. But to see your skills improving with each step really is encouraging. Such fun.
