SCAT Hose Flanges

I refuse to buy a bunch of the expensive metal flanges for the attachment of SCAT/SCEET hose for heating and cooling. So I bought one each of the two most probable sizes if hose I will be using, and used them as a template to make a mold so that I could replicate them in fiberglass. Mold release wax was used liberally on the metal, and then a liberal layer of cabo on the surface (poor mans gel-coat) followed by 4x bid was laid up on the outside of the metal template to make the mold. I added graphite to the epoxy to make the mold black. After smoothing and filling and waxing, I could punch out replicas of the SCAT hose flanges. I will use these on the various air boxes and ducts for the cabin heating and cooling system.
