Holding your knife straight up, trim excess sheeting
flush with dowel.
19.
Lightly sand rib joints along top of dowel, for
smooth fit of top sheeting.
Align one edge of top sheet with L.E. spar, then
flush one end with rib No.2 (the other end should fall over the
joint between rib 6 and 6al). Tape sheeting to spar at several
points along the wing.
20.
With a damp rag, moisten the top of the sheeting
(this will curve the sheeting slightly making it easier to glue to
the ribs in the next step).
21.
With the taped edge as a hinge, lift the sheeting.
Apply a bead of CA along the entire lengths of dowel and spar,
and along the top of each rib.
22.
Wing tip is made from three interlocking ply parts.
Slide ply rib 7 into brace. Install this assembly in wing tip.
Press top sheeting down in position, holding in place
until dry.
Slide brace tabs into rib slots behind main spar.
Push tip fully in, engaging front in rib 6a slot. Glue tip
securely in place. Glue tip rear to T.E. sheeting and T.E.
23.
Starting at rib 6, taper T.E. down to level of ply tip.
Try to keep taper straight. Lightly sand.
Cut T.E. sheeting flush with tip.
24.
Position top T.E. sheeting in rib notches. Align sheet
end at center of rib 2. Remove sheet, apply a bead of CA to top
of T.E. and ribs, and glue sheet in place.
At wing tip, bend sheeting down and glue to tip.
25.
The shear webs to be installed in the next step are
packaged in a plastic wrap as shown in photo above.
Install webs in wing positions shown on the plan as
follows: Apply two ribbons of glue (near top and bottom), posi-
tion webs equally on spars until set. The web between ribs 2
and 3 must be cut 1/16” lower for top sheeting clearance.
26.
Slide L.E. spar brace into slots in rib 2. Push brace
fully into wing until it is flush with wing center. Glue brace
securely to spar.
27.
Repeat steps 2 through 26 for left wing.
