Photo #1 -Left
lower wing ready to be glued.
Photo #2, 3, 4 -This
is the aileron Bell Crank and bracket. Bracket from 3/16 x 2" "U"
channel and the crank from 1/8" T-6, with quarter inch I.D. bushings imbedded
in round spruce ply that has been fiber glassed on the outside. then an
AN4 drilled bolt. It all installed nicely in my compression rib and
held in place with 2 AN3-7 's. Extra holes just in case I need more
or less throw. Bell Crank ended up as shown in Photo #2 & 3 angled
at 54 degrees. I wanted 25 degrees of up aileron and 15 degrees of down.
Turns out to be simple Algebra ...... if 25 degree's equals 90 degrees
and 15 degrees equals "X", then 15 times 90 divided by 25 equals 54 degrees
and that gave me the proper up and down aileron movement.
The main push rod will be 3/4
x .035 t-6 with rod end bearings at each end. From the Bell Crank
to the aileron horn will be 3/8 x .035 steel. It will all align right
next to a rib. 2" lightening holes will be drilled in the quarter
ply facing of the compression rib. Still have to cotter pin, replace a
nut or two and fasten rod end bearings properly.

Bottom Row
Photo #1 - This
shows the ply fill plates around the strut/flying/landing wire brackets.
I will install the pitot tube through this plate and it will also help
when it comes time to cover the wing. Wing is now completed except
for getting the right bolts in place and is shown on the next page.
Photo #2 -The
right lower wing panel is now finished. We (Don Aven & I) made
our own trailing edge. Got some flashing material from the lumber
yard. It comes in rolls about 6" wide and is about .015 galvanized.
We cut 3 inch strips and bent them on his brake. Looks better than
the top wing T.E. made of roof flashing. Each wing panel took
about 70 hours to fabricate. This one took 74 as I had to develop
a mounting system for the aileron bell crank and had to figure out how
to make a wing walk. Damned thing came out pretty good and weighs
exactly 30 lbs., which is a little heavier than the top wing panels but
that was expected. I only used 2 compression panels in this one as
I figured the two inner ribs of quarter ply would serve as a compression
member in the wing walk area.
Photo #3 -If
you raise the tail of an airplane and sight down the trailing edge of the
wing, in relation to the leading edge, you can see if the wing is twisted
or not in relation to the spar. At the tip, you can see the trailing edge
is higher than the leading edge. That was the purpose of this shot and
shows the 1.5 degree washout that probably wasn't necessary but I put some
in anyway.
Photo #4 - My
aileron push rod wasn't going to work as planned, so had to add this idler
arm at the root. The right wing is upside down in this and the next
photo, but gives you an idea of what it looks like and how it is installed.
Improper bolts & nuts in some places as I am still bread boarding to
make sure it works as planned.
Photo #5 -An
earlier photo of the idler arm looking from the outside to the inside.
Right wing is upside down. I will have a short push rod, with rod end bearings
at each end, that will go to the control stick. Improper bolts &
nuts in some places as I am still bread boarding to make sure it works
as planned. (NOTE: Works great!
