Now that the Spar box is made, I held the wing against the wing box and used the two dowel rods to line it up and marked the wing where it lined up with the spar hold downs. I them cut two slot in each wing to accept the spar box.

I turned the fuse on its side and inserted the two wing spars in to the hold downs and put slid the wing on two the wing spar box. Lined everything up, added epoxy and microballoon mixture and glued the wing to the wing spar box. repeated the same process for the other wing.
