Primed the stabilator parts for assembly. While waiting for the parts to dry we riveted the vertical stab frame together and began to skin it. Had a difficult time with the leading edge kinking while forming around the nose ribs. I was warned about this issue by a couple of other builders but still damaged the part to a point I am not happy with the cosmetics of the part. I will order a replacement skin tomorrow. Began to rivet the stabilator together.
