Had a few rivets to finish up. Finished last half of attaching rear spar to skin. Also attached rear spar to inboard and outboard ribs. Had to drill out a couple because in my haste didn't recheck the plans to see which rivet to use and used an 8 instead of 4-6. Still can't make the rivet gun work on 1/8" rivets, only 3/32". Wonder if it is defective in some way. Might send it back to Avery to have them check it out.
