FINISHED THE FRONT AND REAR SPARS. Apparently you now rivet them together later in the build. They are clecoed together and ready for deburring and primer. I was going to set up the wing jig but had some problems with my choice of concrete anchors so I abandoned the jig for now and just clecoed the rear spar to the 10 foot 4 x 4. I did leave the concrete anchor in the floor though so I could trip over it every time I walk by. No time for a Sawzall now, I'm building an airplane.
