February 26 2020 my 3rd sheet of 1/8 okoume plywood arrives.
February 29 2020 attached the vertical “Stiffeners” to the longerons and the aft and fwd skins of the fuselage together with a 9 inch doubler.
Setting a spare section of 4'x4' �nch ply on top of the longerons I used a spare lawnmower battery as the “clamp” to glue together the left and right (fore and aft) skins at the 9 inch doublers.
Realizing that the 9” doubler makes the skin 1/8 inch thicker I had to plane the vertical stiffener under the doublers 1/8 inch thinner.
