Most molded wings have a skin that is a sandwich of cloth, core,
cloth. Emrald was probably glass, rohacell, glass. Some models use
balsa cores and others use herex (another type of foam) cores. Then you
get the expensive stuff with CF skins or even CF both sides of the skin....
Rohacell and Herex can deal with regular CA just fine.

Dennis. . . such tips are surely encouraged for this exchange. Thank
you. This one is a bit confusing. You speak of a "molded wing" in
the first sentence, but later speak of lifting the "foam" to the
skin. I admit to ignorance of the construction of the Emerald wing,
but is it both molded and with a foam core? I thought they were
mutually exclusive. I really don't follow what you are saying. Did
you mean "bagged" wing? I understand about delaminations occurring in
those, but then assume strictly a foam safe CA would be called for or
fixed with epoxy. Please further clarify this tip.

At our club meeting last night, I was showing an Emerald that had a
little delamination on the molded wing. When asking the best way to
fix it, Martin Doney passed on a tip he had learned. It's a small
thing but it really works great. He said to take a tee pin and bend
the tip 90 degrees about 1/8 inch from the end. Poke a hole to drip
in some CA. After the CA wicks in, just rotate the pin and use it
like a hook to lift up the foam to the skin while the CA cures.
These are the little tips that make repairs a little easier, what's
your little tip?
