6. Trim the shaped 1/2" balsa Cowl Sides so
they fit between the fuselage sides and the
Spinner Ring. The bottom edges of the sides
should align with the bottom edge of the Spinner
Ring and the mark you made below the centerline
on the fuselage sides. Notice on the top view of
t h e f u s e l a g e h o w t h e C o w l S i d e s p r o t r u d e
outward from the structure about 1/8" to allow for
shaping.
7. Tack glue both of the cowl sides in place.
View the Cowl Sides and the Spinner Ring from
the front to make sure they are on straight.
Securely glue the parts in place.
8. Fit the shaped 1/2" balsa Cowl Top in
position. Glue it securely in place.
9. Carefully cut the corners at an angle with a
sharp knife as shown in the photos. Use a
sanding block and coarse sandpaper to finish
making a flat area for the Cowl Corners to fit on.
10. Adjust the shaped 3/8" balsa Cowl
Corners so they fit into place as shown. Glue
them securely as shown.
11. Use a razor plane and a sanding block to
shape the nose. You will want to use the spinner
to help you obtain the correct shape, but remove
it while shaping so you will not scratch it.
12. Remove the engine and test fit the
molded ABS cowl in place. Trim the cowl and/or
shim the wood until the cowling fits as shown on
the plan sheets. Use a pen to mark the shape of
the cowl on the fuselage.
