RE: Fiberglass How to: Plug to Mold to Parts
Hi Doc,
This is a very interesting project as I am doing a glider fuselage for a 100" glider in fiberglass. See the screenshots from my CAD in the attached photos. You may also see the 3 view of the project. It's a Dave Jones glider called R-2 from the 80'ies, which I am updating with numerous improvements as I go along.
Your post is timely for me as I am just producing a mold in pink foam. This I will have to sheet with some hard stuff inside as the mold would otherwise break easily.
What could I use to harden the inner shell of the crisp, but brittle pink foam? You can see a simulated run version of my foam mold milled in CNC from a friend (orange below).
