H. Stab final assembly

H. Stab. Skinning - Note poor edge alignment)

H. Stab. Skin Alignment Repair - Note Doublers

Tough aligning top skin stb. It is either flat at trailing edge with bulge at the center of the end rib or nicely fitted at the end rib with dimple and small ripples at the trailing edge. Roger (Zenith ) and Jon (HomeBuiltHelp) suggest best fit. I added a doubler L-angle to help smooth the dimple. Added a non functional doubler on the port side for symmetry. Still has slight oil-can effect, but much better with the doubler. Drilled and clecoed (copper). Ready for removal, deburr, corrosion protection, re-strap, re-cleco, and riveting.
