Stage 2: Building The Wings - Model Airways SOPWITH CAMEL F.1 Instruction Manual

Propeller group:
Referring to Fig.05, laminate the propeller
layers (CLE17). Take care to stack the layers
in the correct order. When viewed from the
front in a vertical position, the stack goes
from longest to shortest with the shortest
layer closest to you. Curved edges would
then be upper left and lower right. A 1/4"
diameter bolt and nut make a handy center
clamp that helps align the layers while the
glue dries.
Remove the bolt and whittle and sand the
propeller to its refined shape. The front of
the finished propeller curves toward the back
when viewed from the side. Begin with the
overall lengthwise curve, then proceed to the
cross-sectional shaping. This will result in a
curved leading edge and a straight trailing
edge after the final shaping. Shape the front
first, then the back to follow the front. Note
that the front surface is slightly convex and
the back is slightly concave.
When you are satisfied with the result, apply
a gold-mahogany stain. If using a water-base
stain you might have to lightly re-sand the
propeller with #400 paper to remove any
raised wood grain, then apply a couple of
coats of varnish.
Attach the front (CLE04) and rear( CLE05)
flanges to the propeller. Make sure the front
and rear bolt heads/nuts line up before
gluing. Dry fit this assembly onto the
crankshaft mount. There should be a space
of about 1/16" between the rear propeller
flange and the camshaft box.
DO NOT glue the propeller to the
crankshaft mount until final fitting of the
engine to the completed aircraft. This will
allow you to make any needed adjustment so
the prop will clear the machine gun muzzles.
The upper and lower wings are built in essentially the same manner,
referring primarily to full-size Plan 03. The primary differences are
