I'm thinking I'm going to glass the fins on my L2 project - a scratch-built, Blue Tube-based rocket. It's probably overkill - Blue is Mach-proof, and the fins themselves are birch ply, which is pretty stout stuff (though I have snapped it on landing before). But I've never glassed anything and the rocket is overstable as it is, so a little weight in the bottom won't hurt.
Question:
Would it be a bad idea to do external fillets on the fins? I'm thinking that even if not for strength, it would make it easier to glass - it would make for a gentler transition from body to fin. Laminating epoxy ought to stick just fine to Rocketpoxy, yes?
