Probably not profitable enough. Carbon fiber tubes from China have gone up in price a lot, they cornered the market now they are raising the price…..what happens when we outsource everything. I ordered 2 carbon fiber tubes of same thickness from China that cost over 25 bucks a pop after shipping so no way he can buy the tubes, machine them and then sell them at 35 dollars, he probably end up making 3 dollars an hour selling them.
