While fitting the longeron, I noticed a fit problem I didn't like. Around the F-711 and F-712 bulkhead, the longeron wouldn't quite sit flush with the skin. Now, if I twiested the longeron inboard a little, it would sit flush, but it had an inboard twist. Not the best thing, since the horizontal stab sits on these things.  Here is the culprit - the longeron is hitting the F-711A/B bulkhead.  While I mulled over this situation, I went to Salty's place to pick up some more clecos. 100 #40's and 175 #30's! Of course I didn't just stop by and leave - there was the multiple hour conversation covering everything RV related. Somehow I got roped into riveting the last skin on his QB wings this Tuesday night. Not a bad trade at all considering all the rides and advice I have gotten from Salty!  OK, so back to my fit problem. I figured I needed to file down the F-711 bulkheads 1/32" or so, but I didn't want to take out the F-711 bulkhead or drill out any of the rivets holding it in. It didn't take long for me to come up with an elegant solution- I inserted a strip of plastic between the F-711A/B bulkheads and the F-711C bar to keep the file from digging into the bar (I got the thick plastic by cutting the bottom off of a Tupperware container). I bent the skin band the pulled the longeron down.  The vixen file had no issues making it in there. Followed up by another file and some emery cloth and the fit was lookin' good!  I found some interference on the F-712 bulkhead too. This one was a piece of cake compared to the other bulkhead. Now the longerons line up perfectly with the skins.
