I looked and looked, no joy. For several scratchbuilt composite airplanes, the method of attaching control surfaces is including a high density foam block (20 pcf foam, Wicks stocked it) in the massive cores, glass the surface, then imbed hinges in the clock of high density foam.
Trouble is I can not find 20 pcf foam anywhere and mine is used up. I did find companies that list that density and others near it, but none of their distributors have any of it, and the maker is only interested if you want a semi-trailer full of it. Anybody know what the currently used options are for this sort of construction?
I can make syntactic foam using simple molds and dry micro at about 32-35 pcf (about 0.51-0.55 g/cm^3) but using a previously engineered material is always a better option in my mind...
