Re: Coordinate Measuring Machine

what type of resolution are you looking for ?

if your trainer is just to show that a probe can work, you could easily use a needle, ground the part, put your positive on the needle and be off to the races.

using a plastic collet would create the electrical isolation on the probe.

using a spring to allow for it to move upon contact would allow for almost everything else.

very simple, very cheap and if you think about it, with a couple springs, you can allow for almost spherical contact.
