Great Planes CAP 232 40 Kit - GPMA0232 - Manual (Page 12)

2. Cut the sheet as shown in the photo to make a top
and a bottom LE wing sheet.
❏
3. Repeat steps 1 and 2 to make the two leading edge
wing sheets for the other wing half.
We’ll start by building the right wing panel upside down over
the left wing panel plan so your progress matches the photos.
❏ ❏
1. Using two large T-pins, cross pin the root end of a
5/16" x 5/16" x 30" basswood main spar over its location on
the plan so it lines up with the wing centerline. This is the
top spar. Cross pin the tip of the spar to the plan with a
piece of 3/32" leftover balsa under the spar past the
location of rib R-10.
❏ ❏
2. Place (do not glue) the die-cut 3/32" balsa wing
ribs R-2 through R-10 on the top spar over their locations
on the plan. Note: The short jig tabs on every rib, should
be contacting the plan.
❏
3. Using the dihedral gauge to set rib R-2 at the proper
angle, pin the jig tabs in place with small T-pins. Again
using the dihedral gauge, pin ribs R-2 through R-10 to your
building board over their location on the plan.
Note: Insert the T-pins at an angle from the rear, so they
can be removed after the trailing edge and bottom sheeting
are glued in position.
❏ ❏
4. Place a 5/16" x 5/16" x 30" spar in the notches of the
ribs, using the dihedral gauge to locate this bottom spar.
Note: Due to the decreasing thickness of the wing
towards the tip, the top
main spar is not pinned directly
to the building board. Instead, the ribs are securely
pinned to the building board. You must follow the
instructions closely on where to insert the T-pins in the
ribs so you do not conceal them under the sheeting,
making it very difficult to remove the wing from the
building board.
