Gauge Pod Idea (pics)
Here's how I make this kind of thing...
I have training as an aviation mechanic (airframe and powerplant). I took a class one semester on composite structures. Basically, you create your shape out of styrofoam, which is what that first mock up is. It's cheap and easy to shape. I bought some from the local crafts store and glued them together with Elmers. Do you rough cuts with a regular wood saw, I used a keyhole saw. You can use a normal sanding block with 60 grit or less for the curves.
Once you have a shape, you do a "wet layup" of fiberglass cloth soaked in resin over the foam. Once its dry, you'll have this egg basically. Then you take a Dremel to it. In this case, i would cut out the bottom, hollow out the foam from the inside, and then sand and paint it as desired.
I don't know anything about plastic injection molding. I wouldn't be able to duplicate my efforts because the styrofoam mold gets used up in the process. I'm exciting to see interest, but I don't know how I would be able to produce this in quantity. I'm a pilot, not a fabricator! I'll welcome any ideas...

its a lot easier, and cleaner to use spray glue, cut the mat or cloth up, and stick it to the mold, then use a paint brush and cake the resin on., also if you want to use the mold again, tape it up first, then do the fiberglass, once it hardens, the heat breaks the tapes bond, and you can pull it right off.... just my 2 cents, worked very very well for me
