Some 8'' concrete forms waiting in the garage to be turned into an upscaled scratch built version of my L1 rocket.
All tubes will fit real nice together with just a veil layer of glass or so on them but will be fairly heavy as the cardboard tubes themselves are about a pound per foot minus whatever the veil layer might weigh.
Now, I have been thinking about a veil layer over the tubes, then a mat layer over that (for strength) then another surface veil layer of glass. Then soak/erode with pressure washer or by whatever means the cardboard tubes away leaving just glass body tubes.
Locally available Bondo glass (6~9oz?) cloth and mat is what I'll be using unless I find better local source.
All to be done with ProLine Epoxy not Polyester BTW.
Objective is to keep it light enough for a 54mm K805 + 3x 38mm J??? peripherals but strong enough for a low end 75mm "M' someday.
I know this has been done before, I just haven't found a good write up on it.
Anybody ever hosed the cardboard out of glassed tubes with any success? Caveats? Gotchas?
Thanks in advance for any helpful input you might have.
Here's an R&D version of the rocket I have in mind.
Negate all weights and altitudes for obvious reasons.
