Sheet Wrapped Graphite Shafts

This is a good video on how sheet wrapped graphite shafts are made. In this particular instance, it's Graphite Designs factory. You get to see some of the quality control measures that they use in the manufacturing process. IMO the hand rolling stage has some potential for human error which can lead to shaft inconsistencies, whereas filament wound graphite is more mechanized and automated. There are pros and cons for each process in terms of shaft consistency, feel, resin content etc. The debate of which process is better will likely continue forever.
