Bent the leading edge skin for the right wing using the vacuum forming method. Used 3 pieces of tape per rib bay to draw the skin together for vacuuming. Went very slowly. No buckling this time - turned out very straight, and got a slightly tighter bend angle this time (maybe 70 deg).
Skin locked down under the pipe, over the plastic.
Drew pipe alignment line 27/32 from the centerline, held with tailpipe clamp.
