7. Use the same techniques to seal the aileron cut out at the other end of
the wing.
The less-accessible parts of the wing are taken care of, so now it’s
time to apply the main pieces of top and bottom covering. Take one
last second to make sure the wing and your workbench are free from
dust and debris.
APPLY THE MAIN COVERING
APPLY THE MAIN COVERING
1.
Partially unroll a segment of MonoKote and place the wing over top of it for cutting the bottom covering—remember;
the clear, protective backing is on the adhesive side, so be certain to lay your parts out and cut the covering accordingly.
Here, the MonoKote is rolled out adhesive side up with bottom of the wing facing down. This will be the piece for the
bottom of the wing. You can use a felt-tip pen to draw the pattern directly on the lm and cut along the lines, or use the
wing itself as a pattern for cutting the covering as shown. There are occasions where one or the other method is best.
Be certain to cut the covering oversize (about 3” around the tip and 2”
everywhere else) for positioning and handling – especially around the wing
tip where you’ll need a “handle” to hold and pull the covering
.
2. Flip the wing over, double-check one last time for dust or contaminants,
then peel the backing from the lm and lay it over the bottom of the wing.
This is called the “inside-out” technique—the lm is rst applied to
the middle of the part, then heated and pulled as we work outward.
When the lm is heated it softens, so it can be stretched while at the
same time it’s shrinking. The result is “pre tensioned” lm that will be
exceptionally tight (and wrinkle-free!) when the process is completed.
3. Starting in the middle, use the iron to bond the lm to the wing while
applying tension as you move the iron along. Press down on the iron to
bond the lm to the wood. If you are working with a wing that has open
structure, perform the same procedure, only bond the covering to the
main spar (or at the back of the leading edge sheeting over the main spar
if your wing has “D-tube” sheeting from the leading edge back to the
main spar).
4. Rotate the wing and perform the same procedure working from the
middle out toward the tip.
Now the MonoKote is bonded only to the middle of the wing. Time to
work from the middle toward the leading edge and then toward the
trailing edge.
