Hi Alan,

Yes, I think you would get a good enough depression for the top plate and
the benefit is, of course, that if the balls are not precisely at 120 deg.
apart, the dimples would be properly aligned automatically. The amount of
discussion that has gone on about this sensor up to now seems to me to be
totally out of proportion to the job. One gets the distinct feeling that
people want to make jobs like this as complicated as possible just so they
can use their fancy machines ;O) I, on the other hand, tend to work mainly
with machines and equipment firmly rooted in the 18th and 19th century when
there weren't even electric motors - and, as I am sometimes called upon to
demonstrate, I can turn small parts more accurately on a lathe made from 3
nails than on an expensive fancy job. So, if I can make accurate depressions
on a brass disk by clouting it with a hammer, I will tend to do that rather
than spend a couple of days trying to figure out how to do it a more
complicated but 'modern' way!!
