Epoxy was spread in the slot and wing roots, the wings were then taped together and to the master shucks. Epoxy was brushed on the wing joiner which is made from 1/8" lite ply and the joiner is slid into place.

Joining the lower wing halfs begins with laying the upper wings into the master shucks with the wing tube inserted. The sweep angle is already eastablished in the upper wing, this step gets the master shucks in the correct sweep for the bottom wing.

The whole stack up is put into the bag and 5 inches of vacuum is pulled. A straight edge is placed on top to verify straightness. The wing will be kept under vacuum for a minimum of 12 hours. I typically like 20 hours better.

The stack up that will get placed into the vacuum bag less the 1 mil plastic sheeting that will go between the shuck and wing sheeting. This is a preventative step to make sure the wing does not accidentally get glued to the shucks. Keep in mind that these are the master shucks and will need to be used 4 sheeting cycles.

Root ribs for the upper wing panels and stabs were made today. The wing ribs are made out of medium balsa with doublers of fiberglass skinned foam. The stab roots are made from the glass skinned foam. The stab adjusters are held in place with CA and CF pins. The position of the stab adjusters and wing anti rotation pins is not critical, I just like to have them as far away from the wing/stab tubes as possible.

The lower wing cores are then glued together with Titebond. The lower wing gets sheeted first because the shucks will need to have 3.5" cut off the root end to sheet the upper wing.

Make a master set of wing shucks. I had to mix and match a few inner and outer shucks until I got a set that matched. Here they have been glued together with Titebond. All wing sheeting will be done using this one pair of shucks.

Once the servo boxes are sanded flush I moved onto installing the stab and upper wing tube sleeves. These are installed with the outter tube supports. The cores are then placed back in their shucks with a plastic sheet between the cores and shucks.
