Month: May 2010

I started off by setting up the wing level on the bench. Actually, the important part was to make sure the main and rear spars where in alignment at both ends. I used a block of aluminum and some tape to mark the level. Once the wing was level, I rechecked the position of the two spar holes. With everything in alignment I proceeded to fit the bottom skin. The tough part was figuring out just how far in or out to place the wing. Once I completed all of the pilot holes in the bottom skin I used my cargo straps to pull the leading edge skin into place. Next, I started to drill the pilot holes in the leading edge skin. I drilled all of the holes in the leading edge except for the holes that go through the main spar.

I moved the wing forward on my bench so that the leading edge skin could hang over the front without getting caught on my wing support blocks. I then leveled the wing using some aluminum scrap as shims and proceeded to position the leading edge skin.

Today I completed all of the #40 holes through the top skin and ribs. Next I need to drill through the rear spar and the main spar. For that process I plan to lay the wing flat and check the twist again with a level. I drilled the #40 holes through the rear spar and then leveled the wing on the bench in preparation for fitting the leading edge skin. Next, I got down the leading edge and started on the fitup.

I setup the right wing on my bench and set the distance between the rear spar attach hole and the center of the fuselage to 19". Next I unrolled the top skin and proceeded to align the skin.

Today I riveted the top skin and the top of the leading edge skin to my left wing.
