Ivan,

Please check if I've messed the dimensions for the front spar on the
drawings below.
................all look good.
Maybe it is a stupid question, but better safe than sorry: spar face with
full plywood web goes in the wing-tip direction for both spars, front and
rear, right? There is a small drawing near the right edge of your sketch
that made me uncertain about that.
................do you mean the grain of the plywood? If so yes main grain
is along the length of the spar
One other thing: vertical stiffeners position on the spar inside edge would
need a hint or two, there are several dimensions (7 1/2), (1/2 + 8 1/2) that
are a bit confusing.
................Not sure what you mean here, the wing join ends are 7 1/2",
the center (wing spar strut fitting) 25 1/2", the wing tip 4 1/2". There is
blocking at each wing rib position, pulley fixing position and compression
strut fitting.
................Does all that help?
Cheers
Peter
