Tonights work continued prepping the wing halves for joining. First, I cut the extra spar material away. Then I used a flat file to file the last of the access. A little sanding, and that was done. I noticed the front of rib #1 wanted to move a little, so I double checked the glue joints.

To further increase wing strength, I added the dihedral brace pieces. On a one-piece wing, these would be one long piece gluing/joining the two halves together. I will only use them for bracing the first few ribs. One brace in the front and back of the wing.

Next, I worked on the shear webbing. The modified wing call for shear webbing in the first three bays. These will help strengthen the wing as well. I added webbing to the back of the spars. Webbing will also go on the front of the webbing. But I will wait until after I get the joint tube correctly in place.

Finally, it was time for the joining of the wing halves. First, I put blocks under the end of the wings. Under the 4th rib from the end. Next, I connected the #1 ribs with nylon screws and wooden bolts. I must have put the #1 ribs in with more of an angle than I intended. There was still a gap between the #1 ribs. By adding an additional 3/4" blocks, I closed the gap. This will be my wing.
