Dynaflite PT-19 - Manual (Page 22)

18. Sheet the bottom center of the wing.
19. Attach a cap strip to the top and bottom of
all the ribs using 3/32" x 1/4" x 30" balsa sticks.
Cut the longer pieces first.
20. Rough sand the wing to shape.
21. Fiberglass the center of the wing with 2"
glass tape. Put a small patch around the wing
dowels as well.
22. Mount the wing to the fuselage and bolt it
into place. While doing so, place some wax paper
at the leading and trailing edges.
25. Use leftover 1/8" ply to make a bulkhead
where the leading edge of the wing meets the
fuselage. First fit it to the bottom surface of the wing,
then use a pencil to draw the outline where it meets
the fuselage. Now trim this former to shape allowing
for the 3/32" sheeting that will be used to fair the
wing to the fuselage.
26. Position the former on the wing. When
satisfied with the fit, glue it to the WING ONLY.
27. Cut and fit 3/32" sheeting from leftover wing
sheeting to smoothly fair the wing to the fuselage.
Glue the sheeting to the former and wing.
28. Remove the wing from the fuselage.
23. Use leftover 1 /8" ply to make fillers for the
TE of the wing where it meets the fuselage. Glue
them to the wing with CA.
24. Adjust the 1/4" x 1/2" fillers that you tack
glued in step 21 of "BUILD THE FUSELAGE" as
needed to fit the TE of the wing.
It's finally time to take all of these assemblies and fit
them together to look like an airplane. We'll start
with the fuselage.
1. Carve and rough sand the stringers to blend
into the fuselage. This is not extremely critical but will
effect how the fabric lays.
