Dynaflite PT-19 - Manual (Page 18)

11. Cut the elevator tips from 5/8" x 15/16" x 6"
balsa. Glue and pin them into position.
12. Glue and pin the shaped balsa elevator roots
into position.
6. Cut and fit the ribs from 1/8" x 1/2" x 30"
balsa. Cut the longer ribs first. When satisfied with
the fit, glue them into position.
NOTE: It is important that the ribs fit the LE and
TE well. It is not important that each rib fit the exact
location shown on the plan.
7. Remove the stab from the plan and rough sand
it to the shape shown in the cross section.
8. Mark the centerline of the stab on the back of
the TE. Place a mark 5/8" on both sides of the
centerline. Place another set of marks 15" on both
sides of the centerline. These marks will be used to
position the elevators.
9. Sheet the stab with 1/16" x 3" x 30" balsa on
both the top and bottom. Do this with the stab flat on
your building board and use care not to twist it as
you glue the sheeting into place.
13. Cut some shims from 3/16" x 3/8" x 24" balsa
and place them in position over the plan at the TE.
14. Cut the trailing edges from 1/4" x 3/4" x 30"
balsa. Glue and pin them into position on top of
the shims.
10. Build both elevators at the same time. Cut the
leading edges from 5/8" x 1/2" x 36" balsa and
pin them to the plans. The leftover 5/8" x 1/2"
balsa will be used later to shim the stab when it is
mounted to the fuselage.
15. Cut and fit the ribs from 1/8" x 5/8" x 30"
balsa. Cut the longer ribs first. When satisfied with
the fit, glue them into position.
NOTE: It is important that the ribs fit the LE and
TE well. It is not important that each rib fit the exact
location shown on the plan.
16. Remove the elevators from the plan and rough
sand them to the shape shown in the cross section.
17. Tack glue the elevators to the stab using the
reference marks you made previously.
