11. Turn the wing right-side up again, and use a
sanding block to shape the LE web so it aligns with the tops
of the ribs and the shape of the airfoil.
Sit back and relax! Take a look at your great work! Enjoy for
just a minute how light and strong this structure is. Okay,
ready to get back to work?
If this is the first time through, go back to the start of Build
the Wing Panels and build the left wing half.
❏
1. Using medium CA, glue the three die-cut 1/8" ply
center spar joiners together. Center these three layers on
top of the die-cut 1/8" ply forward spar joiner so that the
high point of the center joiners is aligned with the peak on
the center section of the forward joiner. The bottom edge of
the center joiners will also be aligned with the flat edge of
the center section of the forward joiner. Glue them in place.
This complete assembly is now called the wing joiner.
❏ ❏
2. Lay the right wing panel right-side up on the
building board. Hold the wing joiner so the forward spar
joiner is facing you and the flat side of the center section is
up. Write “top” on the front of the forward spar joiner at the
flat edge. Without using any glue, test fit the wing joiner
into its position against the spars. Mark a straight line on
the sheeting where the wing joiner meets the sheeting.
❏ ❏
3. Cut the sheeting along the line drawn in step 2 and
along R-2A, and remove the leftover piece of sheeting.
Repeat steps 2 and 3 for the left wing panel.
Be sure the building board is free of debris and items which
will be in your way, because you’re ready to join the wings!
❏
4. Lay both panels upside-down as shown in the photo.
Without using glue, test fit the wing halves with the wing
joiner. Some fitting of the wing joiner may be required. Take
your time and be extremely careful that you have a perfect
fit, with no gaps between the spars, and the tabs on the
forward spar joiner locking completely into both R-2A ribs. A
few extra minutes here will help ensure that you have a
strong, true wing that will perform at its optimum. Note: Be
SURE that you have the wing joiner upside-down, just like
the wings are, so that the “top” label is inverted and is just
above the building board as shown in the photo.
❏
5. When you are confident with the fit and that you can
comfortably position the wing joiner, remove it and lift the
wing halves from the building board. Place a Plan Protector
under the center of the wing to catch excess epoxy. Coat
both R-1s, all four spars, and the wing joiner with 30-minute
epoxy, and install the wing joiner. Place weights on top of
the wing to hold it in place. Do not disturb the wing until the
epoxy is completely cured.
It’s time to take a long, relaxing break and let the epoxy do
its job.
