WELL fellows, I hope your fuselage
assembly is now complete.
Several of our plane builders have
called in to ask just what pieces are to
form the Slanting oblong for the nm.
To construct the lin, as was shown
in last weeks sketch, cut from your
piece. of 1882 by by IL balsa veneer a
strip measuring 1882 of an inch square.
From this cut two pieces IA inches
long and two pieces inches long. Now
continue from this paragraph printed
in last Sundays course through to the
construction of the tail surface.
Other plane building enthusiasts wish
to know where to buy tools and mate
rails. These can be purchased at the
new clubroomS Of the Capital Aero
Club, 1918 I street, and at the model
plane room at Central High School,
where I am teaching classes in con-
struction of miniature craft Wednes-
days and Thursdays of each week from
l to O'Clock in the afternoon. Mate
rails and tools also may be bought at
the Z. ". Brown School, where in
struct class every Tuesday at the
above time.
You are now ready to make your
wing. Slit of two pieces of your 1872
inch veneer, lis inch wide and IL
inches long. These will be for your two
wing SparS.
Measure the centers (6 inches> and
on the 1-16-inch surface press in
lightly with your thumb nail. This will
allow the balsa to bend up at this point
for your dihedral angle; that is, the
wing forms a fiat "V"
BY placing the spars on your glass
and putting a weight, as shown In the
sketch, to hold 1t in place just at the
center, you may bend the remainder up
ward until Is is about 2 inches from
the glass to the spars at the extreme
end.
Now place drop of glue Ii the CEN
ter where you broke it with your thumb
and allow 1t to dry thoroughly.
While waiting, cut off another 1872
inch strip from the 1-32-inch veneer
and cut five pieces from this, each IL
inches long. for ribs. Also cut piece
of tissue 2 inches wide and 12l2 inches
long.
Now that the wing spars are dry, cut
Y inch off each end of one of them for
the rear spar.
Glue one rib in the middle of the
sparS, making them parallel and 134
inches apart; then the second rib mid
way between that one and the end, and
the third, on the extreme end. will be
Slant1ng. Do the same to the other
side of the center, but not until the first
side is thoroughly dry.
Cover with tissue on the top side In
the same manner as you did the I'm.
You will find it easier to start in the
middle and work toward the ends.
When the banana liquid is dry. with
your scissors trim the edges that stick
over, being always very careful.
You will need wing clips to fasten
the wing to the fuselage.
Bend your music wire Cor fine hair
pin) to the shape and dimensions as
shown In Fig for the front clip and
Fig. for the rear clip, using your
round-nose pliers.
To fasten these on. push the points
through your wing spars at the center
and glue with a very small drop.
A piece of your No. z wire, inches
long, will make the landing gear.
