RE: 4*120 Build Thread
The Adjust-O-Jig is no available anymore. Collectors item? I bought it about 6y rs. ago and have held onto it. If memory serves me correctly, it was about $125 at the time.
The mason jar is full of rum & coke, but it looks like all the ice was melted by the time I took the pic. Look hard--you'll probably find a pack of Marlboro Lights somewhere in the pics.

I got the trailing edge sheeting on both the top and the bottom. I got all my shear webs in.
Chris:
The plans don't tell ya to install shear webs in the 2 bays in the center of the wing panles. This is so that the dihedral brace will fit in.
I've made a small change. Most wings will have to install plywood or balsa webs on the front and back side of the spar where the brace goes in. This makes a "pocket" to hold the brace in--and also makes a larger glueing surface for the brace.
Our brace is only 5/32" wide, so you can glue a piece of balsa in between the top and bottm spars. Glue a piece in the front and the back. This makes the dihedral brace pocket smaller and it closes it all up. Now when you install the brace, your glue won't run all over inside the wing panels.
I'm uploading a pic that I drew. This is a top view of the wing panels at the center section. On the left is the LE stock. The dark shaded are in the center is the brace, and you should be able to see the lines that represent the spar and the pocket webs that I've added.
