To All,
For quite some time I have been concerned with the possible internal rust on the Tail components of Firefly007 due to water Exposure. When operating the Firefly on floats the tail is doused with water. Bryan Melborn and I have been building molds for the glass components. The photo included is the right half of the main structure. It is vacuum bagged and curing. It is made from epoxy and structural glass. Not visible is a kevlar internal strap.

Steve,
I looked at this at the homecoming but didn't get time to ask you about it. Are you planning on using the mold to capture the tubing in the tail or is the plan to replace the metal tubing with a composite structure?

This is the prototype from last year build from scratch without molds

Scott,
The part has come a long way since the homecoming. Cold Damp weather is horrible for polyester products. Both right and left hand molds are complete and they are used to build an 1/8 " skin that captures Aluminum tubing. The vertical post is .120 wall . The hard part was getting the glass on the final piece to stay on the mold. By using epoxy and vacuum bagging that problem is solved. The bonus is a piece that is half the weight of a cold layup and probably twice the strength. Epoxy and vacuum bagging also allows the use of kevlar in a couple of key areas.
This part is not for everyone, it is more expensive than the standard steel part and more work to build. Bryan Melborn will probably offer these to people that need them for float planes.
