B2) For larger damage: prepare as shown on Figure 47, but the weaving must
cover the slanted surfaces and extend beyond those slanted surfaces. These
"ears" lie on the spliced edge of the outer FRP layer.
From there follow as shown on Figure 43
For holes big enough to admit a couple of fingers, or where the inner skin hangs
down and flops around most disconcertedly, one must build a light platform
under the inner skin to hold it in place while new fabric is glued to it.
Dress the inside surface of the inner skin to a clean, tapered surface, as shown
on Figure 50. Gloves will protect the hands from sharp edges!
FIG. 50
Cut out a platform piece of foam or other light material big enough to overlap
the hole by about 50 mm (2 in.) all around. Sand off its top surface so that it is a
fairly good fit to the ground surface of the inner skin. Then secure with wires or
strings against the shell. The inserted part must fit shell contour exactly without
distorting the contour.
Practice with a dry-run!
FIG. 51
We cover the top side of this inserted piece with epoxy and glass cloth, so that it
overlaps the splice of the inner FRP layer. After saturating exactly we tighten
the wires or strings against the shell, and let it harden.
