I started tonight by putting a huge glob of ProSeal on the AN fitting that holds the fuel pickup tube. I then torqued it to 110 in-lbs.
I removed the pitot and angle of attack lines. I changed my mind and decided to use Poly-flo or something equivalent instead of aluminum tubing. The reason is because routine the tubing in the area between the wing and the fuselage is likely to be a bigger pain than doing this with plastic tubing.
Christine and I stabbed the left wing. This was a lot harder than I thought because the center section is about 1/32" - 1/16" too narrow in the middle. Instead of looking like || it looks like )(. Actually this is a gross exaggeration because 1/32"-1/16" isn't discernable but is enough to cause problems.
I beveled the edges of the spar. Christine and I tried to stab it and it would not go in. We struggled with it until I ran out of steam. I then beveled the edges some more and beveled the edges of the center section. I then sanded the beveled area and greased it. This time we struggled but were able to find a technique that worked. Christine held the wing tip while I held the inboard part. I found that I could rest the spar on the center section and help twist the wing around until it lined up. When it looked like it was about to go in, I went to the tip and helped Christine push it in. I moved the tip up and down and it worked its way into position. I then used a drift pin to get the holes more or less lined up and then a bolt I had ground off the threads to tap in the final alignment. I then tapped in the home depot bolts which went in easily. Whew.
This too narrow center section has been worrying me for several months. I have no idea why it was )( shaped. Here are some pictures of the end result. I am very please that the rear spar and bottom parts line up almost perfectly.
The picture below is of the space between the wind and fuselage. The blue thing is tape wrapped around the aileron pushrod.
