Very nice! Thanks for all the picture updates!
Thanks, Ben, for your great tutorial on how to build these tubes. To see this with so much details will be a perfect start for somebody who will try the same.
Personally I love the RTM/RTM light-process since it is not such a toxic mess like a wet layup. Building tubes with a standard internal diameter is kinda trivial but changing to an overall toleranced diameter as your tubes is quite a challenge. Have you ever thought about or even tried building the tubes with an infusion process?
great tutorial!
Have you thought about buying liquid latex and gradually rotomolding or layering even by hand?
