The fuselage's stab platform
has two 1/32" plywood plates, which are shown below.
1/32" balsa sheet is laminated
onto the upper side of these plywood plates as shown below. This is to
provide stiffness to the 1/32" plywood and save a little weight.
A countersink recess is drilled
into the 1/32" balsa lamination as shown below to receive the heads on the
2-56 cap screws that secures the fin in the stab slot from the bottom.
This then allows the two
mounting plates to be screwed down flush on the bottom of the stab as shown
With the two mounting plates
screwed to the bottom of the stab, the stab and fuselage were jigged up and
the two mounting plates glued on the fuselage top longerons.
Once the glued dried, the screws
were removed and the stab taken off, leaving the two mounting plates
perfectly aligned and glued in place as shown below.
The stab platform was then
finished out with 1/16" balsa sheet in between the two stab plates and
forward of the front stab plate as shown below. The two countersink recesses
and the four mounting holes were hardened with CA to prevent wear.
The fin was inserted into the
stab slot and secured with the two 2-56 cap screws from the bottom of the
stab. Then a trial fit was made by attaching the stab to the fuselage's stab
platform with the four 2-56 cap screws as shown below.
This is a good shot from the
bottom showing the stab mounting plates screwed to the fuselage.
This final picture shows the
removable fin and stab mounted to the fuselage via the stab platform.
Well, work will cease for the
day now as the Cowboy game will be coming on soon. The repair of my
prescription glasses will require a minimum of five days (all next week).
However, I will try to build the elevators and rudder if I can find some
cheap reading glasses that will permit me to see the
