Re: [PSUBS-MAILIST] motor seals

Hello All:
Sounds like we are getting down to it!  I have access to a kiln and all
kinds of material where I work.  Anybody know what kind of ceramic would be
best to use for such a purpose?  I could make a mold if we come up with some
dimensions.  I think I'll start looking around for magnets.  Any possible
sources?
