7. SEAL THE EDGES (Fig. 10a,10b)

When you have completed covering the bottom of the wing and sealed the

wing tip using a high temperature setting, trim the ORACOVER to about

a ½ cm overlap and seal the edges with the iron (fig. 10a, 10b) - DO NOT

shrink ORACOVER over the framework yet.

8. WING UPPER SURFACE

To cover the upper surface of the wing use the same procedure as that used

for the lower, except you must cut a little more ORACOVER (required at the

wing tip for stretching). Note: Be sure to reduce the heat to low (90 °C).

9. COMPLETING THE COVERING (Fig. 13, 14)

After the top and bottom have been tacked down, it is time to uniformly shrink

the material to the surface. Set the iron to high range (150 °C). Use the same

method you applied during tacking (Step 4). This reheats the adhesive to a

higher temperature, providing a superior bond to the wood (see fig. 13, 14).

Experience shows that once you shrink the covering, some areas may not be

securely attached. We therefore recommend you repeat this procedure. If you

use a heat gun instead of a covering iron make sure you press the covering

firmly onto the airframe surface. This allows the adhesive to set permanently.

You can use a soft cloth (or kitchen roll) to do this or better still: use the

ORACOVER - felt blade (ref. no. 0915), see fig. 9a, 14, 15. If the

ORACOVER is not bonded to the surface properly, wrinkles could appear.

10. COVERING THE FUSELAGE (Fig. 16)

Cut the ORACOVER to the outline of the surface to be covered with about

1 cm of overlap (see Fig. 16). Lay the ORACOVER on the surface. Using

low range (90 °C) tack a centre strip down the length of the fuselage. Using the

entire surface of the iron, work with gentle pressure from the centre strip

outward as shown in Step 4 and 5 (see Fig. 16). Trim the excess overlap to

approximately ½ cm. Increase the iron heat to high range (150 °C). Seal all

edges at this time. Pass the iron over the entire fuselage as you did in Step 8 to

eliminate all wrinkles.
