39.
Use the patterns supplied to make two
WTT's and two WTB's. Cut these from
the scrap 3/32" die-cut plywood brace
WR.
40.
Trial fit the dihedral braces WTT & WTB.
Trim the ribs if necessary, but do not
glue the dihedral braces in yet.
Repeat these procedures for the other outboard wing panel so that you will have one left panel and one right panel.
41.
Carve the leading edge of all wing panels with a single edge razor blade to airfoil contour.
Joining Wing Panels
42.
Sand the leading edge smooth with the sanding block.
43.
Trial fit WTT & WTB dihedral braces in the inner panels at the outboard rib.
Pin down the inboard panel over the plan. Position the outboard panel on the plan
against the inboard panel and raise the tip rib 2-1/4" as shown. If the joint between
the two panels does not match perfectly, sand one or both of the ribs until it does.
Glue the panels together with epoxy
glue. Have a "wet" joint to insure that the
glue will fill any gaps in the seam. Also
epoxy glue dihedral braces WTT and
WTB in place as shown. After the epoxy
has set up, take up the wing panels and
peel off any excess glue that has
squeezed out. It is easier to do this
before the glue completely cures.
Repeat the same procedure to the other outboard and inboard wing panels. You will now have one left wing and one right
wing.
