Default RE: Sig Hog Bipe

So I climbed back in the saddle after the big blunder. I appreciate no one calling my stupidity out; I really feel quite silly about that one - anyway, its behind me and I will not dwell on it anymore.

Now that the distraction is behind me, I can resume joining the wings. Remember, I made that little dihedral jig before, so I'll put it to good use now. I ended up dry fitting the dihedral brace and wing halves together to make sure everything was right (picture1). When I placed the wing onto the Dihedral jig, it looked to be right on (picture2). I decided to join the Dihedral brace to one wing half first, let the epoxy cure, then join that to the second wing half. Picture3 and Picture4 capture the wings when I epoxied them together and clamped them.

Once everything cured, I came back and added the servo lead tubes (construction paper), and the center sheeting - Note - it is much easier to put in the servo lead tubes before the wing halves are joined . The top wing center sheeting had given me a challenge because I had gone "cap strip happy" and added too many cap strips - all the way to the center. It forced me to add supports under the cap strips to secure the sheeting. I believe this made the sheeting much more secure and less resistant to breaking when improperly handling. With that in mind, I added a few reinforcements to the bottom wing sheeting as well (picture5). I went ahead and sheeted both the top and the bottom. I will cut a couple of holes for the servo leads after I glass the center.


Picture1 - Dry fit DB and wings together.
Picture2 - Dihedral angle spot on.
Picture3/4 - Wings joinded and curing.
Picture5 - Additional support for center sheeting at trailing edge
Picture6 - Additional support at butt joint of sheeting pieces
Picture7 - Bottom wing - added a bit of filler ahead of sanding
