Great Planes Super Skybolt 60 Kit - GPMA0170 - Manual (Page 41)

D 26. Cut a rectangle out for each cabane wire.
Start the rectangle out small and gradually enlarge
it to allow the wires to easily slip into place. When
the rectangles are correctly sized so the wing will
easily slip on and off without hitting the wood, soak
the area around the rectangle with thin CA to
reinforce the wood. A small strip of very light
fiberglass cloth (3/4 oz. or so) can also be used to
reinforce this area.
D 27. Wet the LE and the TE sheeting at each
wing tip. Allow it to soak in for about 5 minutes.
Then press the sheeting up against the wing tip
and glue it in place with CA. Do the top and bottom
sheeting at the same time to keep from bending
the tip.
D 29. Use a straightedge to draw lines on the LE
sheeting along the edges of the T7 rib assemblies
as shown in the photo.
D 30. Carefully cut through the LE sheeting to
expose the front I-strut slot. Take your time and
cut a little at a time to end up with a neat looking
slot similar to the one in the photo. Notice that the
edges of the slot are tapered outward to make it
easier to install the I-struts later.
D 28. Use a 1/16" x 2-5/8" x 13-1/2" piece of balsa
wing center sheeting to finish sheeting the wing
tips. Cut a piece about 2-3/4" long (to fit over rib
T8) and glue it up against the LE sheeting. Then fill
in the gap with some scrap 1/16" balsa. Trim the
ends to the shape of the wing tip and sand the tip
smooth. Do this to the top and the bottom of both
wing tips.
D 31. Cut through the TE sheeting to expose the
rest of the rear l-strut slot. The front portion of the
rear slot will be cut out later after the cap strips
have been installed. Pick or blow all the balsa
scraps out of the slots when you are done.
