Hi Chris,

Excellent idea!  Will have to check on my "stock" tomorrow; which has been
chopped up over the years
for various projects.  Anyway....that approach is indeed likely very
suitable and available in alot of places
and over the internet.  Thanks for your earlier positive email opinion of
the use of magnets in a crossed rod
or crossed cylinder axis/pivot, as that helped accelerate this
experimentation.

Using a layer of metal on magnets approach; reminds me of the good old
diamagnetic levitation experiment
times, which was also your very good idea for certain varieties of
setups/models we saw.

Hi Meredith,
 
    You just need a hard surface. Could you use a thin steel feeler gauge?
