Riveting the spar back together. All looks good till you go to pull the rivets in the L angles. Rivet holes to close to the flange for the reviter to get onto the rivet. Fortunatley the lathe came in handy again to make a small button spacer. Slipped that between the riveter and rivet. Just enough room for the rivet puller and still enough stem to pull. Just!. Broke a few and it was slow but progress was made.
