This is why I love to Sail

Fixturing and method are of prime concern, had to do some thinking about how to build the boost in both effecient thrust and more effective re-generation from the 3 blade 14/11 prop being used...

Being round (the Nozzle) and configured like an ole barrel with a specific airfoil on the inside diameter and outside it is necessary to have a rotary device, if you happen to have a 20 inch lathe, you have no problem, I don't, so had to make from scrap parts laying around Doc John's dungeon.....good place to scrounge....thanks Doc

Building a drum that will be filled with 8 lb. foam and then shaped to form the inside diameter of the nozzle.

We add a cardboard inclosure around the drum to hold in the foam as it expands.

The mixed 2 part foam is then poured in the mold to form the backing for the shape form of the inside of the nozzle.  The nozzle inside diameter and form as well as the correct projection will be machined into the foam.  When the epoxy and fabric is wound around the drum the outside form will have to be machined next.
