Wing
tip
details. I prefer wing tips that sweep up as they are easier to
cover but this type is easier to build. On the top a separate
piece of covering must be used from the last rib out.
Triangles were
puchased from OSH, a local hardware store. Holes are
drilled in the flanges so they can be pinned to the building board.
This method
results in very true
wing alignment. Wing spars butt together at the center line and
the dihedral brace is very effective in setting and checking the
dihedral angle.
There are reference
lines on the plan to align the wings and and triangles.
It worked best to set the Simplex wing panels on the trailing
edge as the leading
edge is not at the
bottom of the wing surface and would not touch the supports. The
name for the square is Swanson Speedlite Square,
mine are 8 inch but
they also are available in 12 inch sizes. http://www.swansontoolco.com/product/speedlite-square-orange/
