part - be sure your core looks exactly like that on the section view.
Lay a 12 inch straightedge spanwise on all critical areas of the
flying surfaces and be sure you don't have any high or low places or
joggles. Measure any areas that involve fiberglass buildups to check
for correct depth. Build up is 0.009 inch per ply for UNI and 0.013
inch per ply for BID.
STEP 4: MIX EPOXY
.....
Mix epoxy when you need it, not before. Micro, dry micro, and
flox may be required at various stages of the layup. Mixing and
composition details were covered earlier. Apply a coat of micro slurry
to the foam surface before the first glass ply is laid over it. The
slurry can be poured on the foam and spread thin with a squeegee. Fill
any dings or gouges in the foam core with dry micro prior to applying
the slurry.
STEP 5: LAY ON THE CLOTH
.....
Lay on the cloth in the specified orientation. Pull the edges to
straighten the cloth out and to remove wrinkles. Maximum strength and
stiffness is obtained if the fibers are not wavy or wrinkled. If the
cloth is to be applied around and/or into a sharp corner, you will
find the job easier to do if the fiber orientation is at 45° to the
corner. Don't get depressed if the layup looks like a hopeless mess at
this point. Press on with patience and things will work out fine. To
remove wrinkles, study the direction of fibers, follow the fibers to
the outer edge of the cloth and pull on the outside edge. Pushing a
wrinkle off the part is incorrect. Once the part is free of wrinkles
use a squeegee and make light passes from the center outwards to
smooth the cloth.
STEP 6: WET OUT THE CLOTH
.....
Do not use micro between plies of cloth. Wet out the cloth by
pouring on a thin coat of epoxy. This may not be necessary if there is
enough epoxy under the cloth to be brought to the surface. This is
done by "squeegeeing", which involves drawing the squeegee over the
cloth. This brings excess epoxy up from be¬ low to wet out the cloth,
resulting in a weight savings as compared to adding more epoxy on top.
REMEMBER, epoxy adds no strength beyond what is needed to wet out the
white color of the cloth and fill air voids; any further addition of
epoxy is only dead weight.

Where multiple plies are required, the first plies may be laid up
