RE: [PSUBS-MAILIST] motor seals

Jon,
This isn't really seal related but I was just looking at your Microseeker.
Do you have any dynamic stability problems with your hull?  The shape in the
picture is almost exactly what I was talking about for a laminar flow hull.

Okay, I've done a design for what I'm going to use for MicroSeeker.

Note that the thrusters in MicroSeeker are only 1" in diameter, but this
should hopefully give people some idea of what I think will work.

You can see the image at http://www.huv.com/MagneticCoupling.gif

I'm getting my rare-earth magnets at Radio Shack, but of course I can use
little tiny ones... I'm not sure what size I will need to do the proper
torque transfer, but I'll find that out when I build it :-)

Later,
Jon
