Thanks George.
On to the stab cores:
Layout the skins using the foam core and shucks to trace the perimeter. The stab skins will require some carbon fiber reinforcement near the stab tubes. These c.f. strips are included in the kit (0.007" x 1" x length"). The locations for the c.f. are shown on a drawing (on the CD). I have used the laser cut stab root rib as a double check to mark these locations on the skins. Line up the root rib to the drilled stab tube holes on the cores, then make a mark on the top of the foam shuck at these hole locations. Transfer the marks to the skin. I then use CA to glue the c.f. to each skin (the inside of each skin

. Alternatively, one could use the polyurethane glue on the c.f.
The skins are now ready for polyurethane glue.
