Separate the lite-ply
wheel well floors from the wheel
well frames using a scroll saw or
hobby knife to cut at the dotted
lines shown in the photo at left.
The lite-ply shear web at
the wing root is also used as a
dihedral gauge during wing
construction. To avoid any
confusion, mark the shear web
as shown in the diagram.
A 1" x 3" x 4" chunk of
balsa is provided as material for
the wing bolt support blocks.
Use the shear web from the previous step as a template to mark the
proper shape of the support block as shown in the photo. Cut the block
into two pieces, and discard the scrap.
Glue the balsa dowel support blocks to the lite-ply dowel block
doublers. Line up the aft edges of each part.
Locate the six pieces of 3/32" x 3" x 36" balsa, then select the
two lightest, softest pieces to use as shear web material. The remaining
four pieces can be set aside to use as trailing edge sheets.
Inspect the 18 sheets of 3/32" x 4" x 36" balsa
supplied in your kit and select eight pieces to use for leading
edge sheeting. Look for medium weight, long-grained sheets
that bend uniformly. Assemble four sets of LE sheets. Trim
the edges, then glue with yellow glue or thin CA.
The remaining ten sheets are used for center sheeting. Assemble two big sheets as shown below, then cut
them in half to make four center sheets. If you are going with open rib bays, cut the sheets first to a length of 23".
Finally, make two sets of wingtip sheets from 3/32" x 4" x 7-1/2" balsa.
