Funny, I was talking about that design recently.

I was thinking more about a shaft driven propeller though. The way I saw it working, is that the prop would have a hub, and would sit inside a grooved out tube. Teflon would form that groove.

But what I can't get over, is the cam box required, to insert the rotating shaft in the tubing. Maybe this magnetic drive has potential, but what exactly holds it in place, when the pump's turned off? A simple crosshair?

Now I've already got 2 Johnson pumps, and a Little Giant 2-MDQ-SC, so I really don't need another pump, especially not a home made one, but it's still interesting.

I have no idea where you'd get one.
