Fibreglass Tube Ring

These are the cast fibreglass sections for one tube ring. It was actually formed in one piece and cut in half to produce the 2 section seen here. Twelve layers of fibreglass tape was first wound around the circular part of the mold, with the remaining space filled with pieces of cloth & resin.
