|Making a Windshield Pattern
|Measure the length of the window opening and transfer that
dimension to a piece of paper
|Cut a piece of paper to the correct length, and more then wide
enough to wrap around the fuselage
|Determine the cabin width at the top and transfer that dimension to
the paper pattern. Then determine where the pattern will begin to
roll around the forward-most end of the wing root and cut it to that
dimension along the cabin sides
|Roll the pattern around the side of the cabin, hold the fuselage up to a light source so
you can see through the paper to the underlying frame and mark the outline for trimming.
Fold the pattern on the centerline to insure that it will be symmetrical on both sides. Cut
along the lines to remove the excess paper and fold the pattern back open.
|Tape the pattern back on the fuselage and
fine tune the fit. Remove and trim as needed
to insure proper fit and alignment
|Once the final shapes are achieved, tape the
paper patterns over the appropriate thickness of
acetate. Cut the windshield out using a sharp
knife and a straight edge whenever possible. A
sharp scissors is used to cut the curved lines.
|Starting at the top and working downward, glue the
windshield into its opening. I use medium Cya very
sparingly, and accelerate it to prevent the "frost" from
forming around the glue joints.
