Thin Epoxy

[Farrell]

They have results of a test they did on balsa wood comparing the penetration of a variety of epoxies. Most soaked in one to three inches. Their thin stuff soaked in 20 inches. Don't know that it would soak into 20 inches of maple.

Part of the thing would be to apply the thin to the laminations to harden them, and then epoxy the laminations together with thicker epoxy.

Whatever. I gotta go to bed.
