Dynaflite PT-19 - Manual (Page 14)

16. Prepare the 1/4" x 3/4" LE that you
installed in step 11 for sheeting. Carve and sand the
LE to blend with the tops of the ribs. Use masking
tape on the ribs so that you don't alter their shape.
17. Glue the leading edge skin that you
prepared in step 2 to the top spar, ribs and LE using
aliphatic resin.
18. After the glue has fully dried, remove the
wing from the building board.
19. Carve and sand the TE and LE to blend
with the bottom of the ribs as you did in steps 14
and 16.
20. Trim the LE and TE sheeting and the spars
even with ribs W1 and W11.
23. Fit and glue the 1/8" die-cut ply webs to
the front of the landing gear rail using 30-minute
epoxy. The webs should fit tightly between the ribs,
sheeting and landing gear rail.
24. Using a 1 /4" bit, drill a hole through the
landing gear block into the stub block. Radius the
top of the hole to fit the bend in the 1 /4" landing
gear wire.
25. Using the 5/8" x 2" x 8" balsa block, cut
and fit the TE filler block between W1 and W2. Glue
the block into place with medium CA. Carve and
sand the block to the contour of the ribs.
21. Glue the landing gear stub block to W2
using 30-minute epoxy. The block fits into the long
cutout in the 1 /8" ply doubler.
22. Check the fit of the landing gear block in
ribs W2, W3 and W4. When satisfied with the fit,
glue it in place with 30-minute epoxy.
26. Prepare the trailing edge for sheeting.
Taper the trailing edge of the 3/32" x 3" sheet that
was installed in step 12 to blend with the contour of
the ribs from W1 to W6. Use a 3/32" x 3" x 24"
sheet to sheet the top of the trailing edge. Trim the
sheet to fit the 3/32" x 15/16" sheet installed in step
15. Glue the sheet in place with aliphatic resin. Use a
long T-bar sander and weights to align the ribs and
hold the rear of the wing flat to the building board.
