D D 6 When satisfied with the fit, apply a generous bead of
epoxy or med or ihick CA to the spars and install the braces on
both sides of the spars Use the die-cut C2 clamps (SPT1W22)
to hold everything in place Wipe off any excess glue before it
cures.
DD 9 Drill a 13/64" hole down through the hole in the front
wing bolt plate and through the 1/16 bottom sheeting Lightly
sand the tops of the inner panel ribs and the spar to remove any
glue globs or uneven places
DD 10 Check to make sure one edge of the 1/16" x 3-1/2"
x 30" Balsa Top Leading Edge Sheeting (SPT1W25) is straight
and if not, cut it straight with a straight edge
D D 7 Locate the two 1/32" Die-Cut Ply Leading and
Trailing Edge Braces (SPT1W10) were next to the Polyhedral
braces you used earlier Test fit them in place and sand them, if
needed, to make them fit between the rib W2 and W4 The LE
brace should be at least 1/16 below the top of the LE to allow for
the 1/16 top sheeting, which will be added later Glue them in
place with med or thick CA If the TE brace extends above or
below the surlace of the sub TE, sand it flush
DD 8. Install ribs W3A and W3B (SPT1W06) between the
inner and outer panels using med. or thick CA as shown in the
photo A little sanding may be necessary to achieve a good fit
Use the rib gauge to tilt the ribs to the proper angle
DD 11 Position the 1/16 sheeting in place so the straight
edge is against the leading edge and one end is covering W3A
Apply several strips of masking tape to hold it in place and act as
a hinge for the gluing process Press the sheeting onto the ribs and
trim it flush with the back edge of the spar using a modeling knife
and straight edge Be careful not to cut into the thread when
cutting near the root of the panel
DD 12 Lift the sheeting up and apply a bead of med or thick
CA along the top of each rib and along the top spar Quickly press
the sheeting down into place and hold it until the glue has cured
Keep the sheeting pressed against the ribs and the spar while the
glue cures A straight strip of wood the length of the panel can
