If its soft anyway....just throwin' this out there......but how about Sonotube or similar? I have seen a few bigger projects use that. I know, there are a lot of opinions on that both for and against. I was planning a big build and was going to use it.I used them for my 98 Deuce - pretty soft, glassing required. Ken also had a nose cone, couplers, and centering rings.
If you were going to do that would it make sense to wrap the sonotube in mylar first? It would come out a lot cleaner after soggification, I would think.Doesn't anybody soak the sonotube out anymore? We glassed some and threw them in my buddy's pool to let them soggify. Totally rank amateur attempt using jigsaws, routers and glassed foam parts. It flew. 20-25 years ago.
