We finally got the main spars all riveted up. glen bought a big rivet gun at Princess Auto and cranked up the air pressure in his large air compressor and it made quite a difference. No problem getting the #6-25 rivet, we had to modify a 10 pound sledge hammer into a bucking bar, that made a big diference as well. While we were trying to figure out what to do next, we realized that we didn't install the 5 angle things, oh well, we will have to drill out 10 rivets per spar to get those in tomorrow.
