Picked up a "new to me" bench grinder and a new deburring wheel so I could actually clean up and contour the ends of the tubes. Crimped ends of elevator tubes to required 3/16" thickness and deburred afterward. Drilled holes in both the tubes and their leading edge counterparts. Manual rivet gun used to assemble tubes to leading edges. Edit: After reading the supplied manual that came with the kit, I realized the inboard rivet is not to be put in yet. It will be removed for future install of elevator installation.
