The whole project is a bit of a learning curve. I wish I could say that I had used some ultra technical ground breaking method of construction!!!!! The fact is the Tubes have been made around a simple former. The seat post for example was formed around a vacuum cleaner attachment hose (nice gradual taper) The former was wrapped in Release Tape, a length of 200grm 2/2 twill cloth (3 X tube diameter) cut and wet laid around the the former. Once that had become touch dry the Carbon Braid was slid over and Resin applied. Wrapped in Heat Shrink Tape and warmed with a heat gun to consolidate the layers.
