propellor and adapt it to suit your size requirements - of course this
may not be the most efficient in the water but it would be your own
design and manufacture.

If it's not too much trouble, I'd be interested in a smaller version
of a propeller. I want to make a small brass fan (propeller) to use
on the ceiling fan cord. one pull chain would be a fan, the other a
lightbulb. that way, one would know instantly what was being pulled.

As for propellers, I know that airfoils are listed in some registry.
I have seen kit planes with the airfoils listed as some 'NASC' design.
forgot the actual letters. do propellors have some similar registry ?
