CANOPY AND CANOPY BASE ATTACHMENT
The molded plastic canopy base has three (3) factory drilled holes
on each side.
These accept the 4-40 x 1/2" nylon mounting
bolts, used to hold it in place. Begin by using masking tape to
accurately position and secure the base in place to the top of the
fuselage. Make sure the base is firmly in place and that its front
and rear mounting lips are over the fuselage. Use a fine point felt
marker pen to mark the position of each mounting hole on both
sides of the fuselage - remove the canopy base.
From your kit contents, locate six 1/8" x 3/4" sq. plywood
mounting pads, six 4-40 x 1/2" nylon slotted bolts and six 4-40
blind mounting nuts. Center one of the plywood mounting pads
directly behind one of the hole marks just made, holding the pad
firmly to the inside of the fuselage side. Use a 7/64" dia. drill bit to
drill through the fuselage side and the plywood pad - remove the
pad. Use a 5/32" dia. bit to enlarge the hole in the pad. Apply glue
to the face of a 4-40 blind nut and press it in place into the pad.
Apply glue to the face of the pad and press it in place to
the inside of the fuselage side, with the blind nut aligned with the
drilled hole. From the outside, thread a nylon bolt in place through
the hole and into the blind nut. Screw the bolt in place, bringing the
ply pad firmly in contact with the fuselage side. Wipe off any
excess glue. Repeat this procedure for the remaining five holes.
With all holes drilled and all pads and blind nuts in place, the nylon
bolts must now be trimmed in length to clear the inside surface of
the canopy base. Use a sharp, single-edge razor blade to cut 1/4"
off of the length of each bolt.
If desired, the canopy base can now be detailed.
On our
prototypes, we used light gray art paper to line the bottom and
back of the canopy base, giving it depth and color. We measured
and cut the paper to fit and applied it to the base with a heavy coat
of spray cement. We used a commercially available instrument
panel - the Hanger 9™ CAP 232 panel - mounting it with epoxy
glue. Last, we used a Hanger 9™ 1/4 -Scale Civilian pilot figure to
finish the cockpit. No matter what pilot figure you decide to use, be
sure to reinforce the bottom surface of the canopy base with a
piece of 1/32" plywood, epoxied in place. This stiffens the canopy
base and allows you to drill through the bottom of the base for
mounting screws to secure the pilot figure. We finished off the
overall look of our CAP cockpit using black twill tape to simulate
the shoulder harness restraint belts and a few pieces of light
aluminum sheet to simulate buckles and harnesses. Overall, it
looks believable and does not add much weight.
To mount the canopy, first wash it in warm sudsy water to remove
any hand oils, mold release agents, etc.
Rinse and dry it
completely with a soft cloth and avoid handling the inside surface.
Use 220 sandpaper to lightly scuff the canopy base edge, where it
contacts the canopy itself. Wipe off excess dust with alcohol.
Mount the canopy base to the fuselage with the nylon bolts. Use
slow cure epoxy to mount the canopy. Mix a small amount of glue
and use a small stick to apply the glue only to the sanded edge of
the canopy base - apply a reasonable amount but not so much that
it oozes.
Carefully place the canopy onto the canopy base,
easing it into position. Use alcohol and a paper towel to wipe off
