Dynaflite PT-19 - Manual (Page 8)

1. Place the fuselage drawing on your workbench
and cover it with wax paper from bulkhead D aft. Begin
construction by building the right rear side structure.
2. Using two 1 /4" x 15/16" x 42" balsa sticks,
cut and fit the rear side stringers. Cut the longest
pieces first. Pin and glue the parts into position.
3. Cut the diagonals from a 1/4" x 1/2" x 30"
balsa stick and glue into position.
6. Place the right fuselage side over the plans
and mark the locations of bulkheads B, C, D, E, F,
and G on the side. Place the left side over the right
and transfer the marks to the left side. Next, mark
each former at the center of the bottom edge. Place
the fuselage plan on your building board and draw
a line down the length of the plans along the
fuselage center with a long straightedge. These
marks and lines will be used to align the fuselage in
the following steps.
7. Glue bulkheads D and E to the right fuselage
side using 6-minute epoxy. Be sure the bulkheads
are at a 90 degree angle to the side. Epoxy will
produce the strongest joint but you can use thin CA
with accelerator if you are in a hurry.
4. Fit the ply fuselage front to the fuse rear. Cut
doublers for the two joints from a 1 /8" x 1 /4" x 30"
balsa stick. When satisfied with the fit, glue them with
6-minute epoxy.
5. The left fuselage side is built over the right
side. Remove the right side from your building board
and turn it over. Use the leftover 1 /8" x 1 /4" stick to
shim the forward ply side. Cover the side with wax
paper. Follow steps 2, 3 and 4 to build the left side,
aligning the parts over the right side.
8. Glue the left fuselage side to bulkheads D and E
using 6-minute epoxy. Align the side with the marks
