Digitizer Probe

I've uploaded a digitizer probe that anyone can build. The dwrawing
may be a bit "sketchy". The idea is there but you'll have to work
out the dimensions to suit yourself....also the details of how your
going to put the contacts in the contact plates. This probe...if
built properly will open the contacts using very small amounts of
travel with any movement of the probe.

All the components are round. Three springs are inserted between the
upper contacts and the top of the housing. The top and bottom of the
housing can be made to screw on for ease of assembly or repair.

How it works should be fairly obvious, but I'll be happy to let
anyone know who can't understand it.
