That sounds interesting. Not to hijack this thread, but I’d like to see some pictures of that process If possible.Building my own from fiberglass cloth and epoxy. ( 29mm, 38mm, 54mm, standard sizes. Then up to 8" in various non-standard sizes. Up to 60" long. )
Were I work we manufacture industrial induction heating coils on fiberglass tubes. Only minor adjustments were needed to get a smoother finish for rocket use. Still tuning the process for best results.
