I am wondering what is the best method to make a carbon tube, what to use for a mandrel and how to get the finished tube off. I have searched for styrofoam tubes on the internet with not much luck, can't believe it. I just made a fiberglass tube over a waxed steel tube with holes drilled all in it and thought that hitting it with some air pressure might loosen it, it won't budge as it is. I also tried parchment paper on my first attempt and it didn't work either, although after I cut it off the steel tube the parchment peeled right off of the fabricated tube. Does anyone have a proven method? It would be greatly appreciated.
