12. Before you glue the LE sheeting in position,

remove the T-pins from the front jig tabs in the wing ribs.

❏ ❏

13. Wet the outside of the leading edge sheeting so it

will bend easier. (Hint: a 50/50 mix of water and alcohol or
ammonia helps break down the wood fibers so the sheet is
even easier to bend). Run a bead of medium CA down the
leading edge of the sheeting. Position the front of the sheet
against the LE of the wing and use accelerator to hold it
there. Wet the sheet once more if needed.

❏ ❏

14. Carefully lift the sheeting away from the ribs.

Working quickly, apply a bead of medium or thick CA to the
top of each rib where the sheeting contacts the spar.

Pull

the sheeting back toward the main spar as you

press it

down to the ribs and spar. Use masking tape, T-pins or
weights to hold the sheeting to the ribs until the CA cures.

❏ ❏

15. Remove the T-pins, then flip the wing half over on

your building board.

❏ ❏

16. Use a sharp hobby knife to remove the tabs from

the top of the wing. Use a sanding block with 220-grit
sandpaper to clean the edges of the ribs where the tabs
have been removed.

❏ ❏

17. Using a razor saw, trim the spars, LE, TE, LE

sheeting, and TE sheeting flush with R-10. Also trim the LE
and LE sheeting flush with the edges of R-2.

❏ ❏

18. Using the spars and the TE as a guide, sand off

the TE sheeting at the root of the wing.
Note: DO NOT SAND the shaped TE or the spars.

❏

19. Glue the TE and LE sheeting onto the top of the

wing following the same procedures you used on the
bottom of the wing. (Steps 10-14)

❏

20. Trim and sand the TE and LE sheeting using the

same procedures you did on the bottom of the wing.
(Steps 16-18)

❏ ❏

21. From the 3/32" x 1/4" x 24" balsa sticks, cut cap

strips and use medium CA to glue them to the top and
bottom of ribs R-4 thru R-10.
Note: Do not put cap strips on R-2 or R-3, as they will be
sheeted after the wing halves are joined.

❏

Repeat steps 1 through 21 to build the left wing panel

over the right wing drawing on the plan.
