Wings
•
Wings are constructed in four panels. Panels
are joined by laminated plywood joiners with
the inner two panels permanently joined
around a center laminated rib.
•
Locate the plywood center wing joiner parts
and the center rib plywood and G10 parts.
Stick T-pins through alignment holes and
epoxy parts together.
•
The center and outboard wing joiners are three
pieces of plywood laminated together. The center
rib is three pieces of plywood and two pieces of
G10 laminated together with the G10 added to
the outsides of the lamination.
•
Locate all the wing ribs and shear web parts,
break them out of the laser cut sheets, lightly
sand off the nubs, and group them in order.
This helps ensure that you have all the
necessary parts identified and speeds the
build process.
•
Peter recommends NOT build the wing
panels over the plans, but rather to use the
plan as a reference. The reason is the paper
plans can change dimension with time and
humidity causing a mismatch between the
parts and the plan. Establish and straight
reference line on your building surface and
scribe a perpendicular reference line at one
end. Align the lower spar with the reference
line running down the worksurface and the
first wing rib with the perpendicular
reference line.
