silverquill:Sounds interesting! Drawing the line between small/common decorative displays and what you might really want cold be tricky. They might need to be different for ship screws and plane propellers. But, I think this category idea has merit! I'd be glad to lend a hand to get the screws turning!
Where to draw the line is tricky and depending on the picture any prop could look big without something to scale it by. A wide shot with the area surrounding it could solve that, but what to use as a starting point for submissions?
Does anyone know what the largest available boat prop is, one you can just walk in off the street and buy? I'd say if you can order it through Bass Pro then it is definitely to small. We need to talk in feet here.
Gotta go to work, more later. Thanks for the interest and the pictures!
