F-6111 stiffeners and top skin work: 5.5 hours

I spent the majority of the time (4 hours?) fitting the F-6111 skin stiffeners just aft of the cockpit. These are supplied partially bent, un trimmed and un drilled. As you will see in the photos when installed the have a bend and a twist to make the lie down against the skin.

After a lot of research on the VAF and various builder web sites I got the right side fitted. After having done the right side the left side went quickly. The fitting process involved marking a centerline on the piece, starting at the bottom of the piece drilling a hole, checking fit, removing piece, making adjustments, reattaching piece, repeat, etc, etc.

The prep work on the top skin went quickly. I got the skin, gusset and stringers all drilled. I also removed a the remaining 4 temporary pop rivets and did some miscellaneous trimming and fitting.

The skin is now ready to be edge finished, deburred, dimpled and primed.
