Now that we're satisfied with the fit of the top main spar, the top rear spar, and the leading edge it's time to go ahead and glue them in place.
(NOTE: If you are using CA you will need to use thick CA to glue the spars in place. This will give you enough time to apply the CA and still get the spar in place.)
Picture #1,#2, and #3 show applying a bead of glue to the notches and top of the shear web. Just like gluing in the shear web to the bottom spar you don't want to skimp with glue here, we want this to be a strong joint. Once you have the glue in place go ahead and put the top main spar in place. You will need to put weight on the spar to hold it in place while the glue dries. Picture # 4 shows holding the spar in place. I've used the fixtures from my building system to hold it down, you can use anything that will safely hold it in place. Now do the same with the top rear spar. Picture #5 shows the spar being held in place with weight bags (I did not have enough fixtures of the size needed to hold both spars at the same time
). Before gluing the leading edge in place I marked the location of the ribs while I was test fitting it in place. I apply the glue to the marks that I made and put the leading edge in place. Picture #7 and #8 shows the fixtures I used to hold the leading edge in place while the glue dries. Once the glue is dry you can now remove the wing panel from the building board.
Ok, now we are caught up with the posts now. This evening I will be removing the wing panel from the board and I plane on addressing Tigerdude's problem with the wing tip.
