Bent the rear spar pieces (200mm long), then match drilled all the parts for the front spar pieces. For the first time in months, I pulled out the pnuematic riveter and secured the front spar jig pieces with 6-14 rivets. Piece of cake, and kind of fun when you are only doing 8 total. Finally I test fit them in the center spar, and did a small amount of enlarging of the jig insert holes (not the holes in the certer spar!). Ready to mount the the front and rear spars to the jig web.
