Tool touch probe for turning center?

Has anyone implemented a touch probe for tool offsetting/measuring in LCNC? I have a four way probe taken from one of the Mazaks. They replaced it with a new one because they thought it was bad, but it turned out to not be the probe. Service guy did not want to deal with uninstalling and reinstalling again, so left the new one in, and wrote it off, leaving me the old one.

So I'm looking at this thing and wondering why I don't use it in this turning center... Easy enough to build a little arm to swing down into place... Haven't quite worked out how to control it yet, though. I imagine I could get a small servo to drive it, or I could use a small stepper. ( but I already have the 7i77... )

Then there'd need to be some manner of routine/macro/subprogram to drive the probe arm down into position, wait for a signal that says it's in place and also prohibits running the machine, and then allow the user to probe a tool tip. Then another that runs the probe arm up for storage, and a signal that says it's safe to run the machine.

But I digress...

So is this something easily enough done? My gut says "yes" since it's done in the mill side, but wanted to ask those in the know.

Thanks.

I made a tooleye for my lathe but there is no "arm".
It is a hollowed out aluminum block with 2 pushbuttons (and a LED).
Has dowel pin in side, that is how the machine chucks on and makes location of it is repeatable.
There is a program for each axis that updates the tool table upon touch-off. Push button just needs to be wired to an input. Added this to .hal file:
#######probe########
net probe parport.1.pin-02-in-not => motion.probe-input


Of course, the machine must have a general idea where the tooltip is, or it will crash.

I have a short video of me running X prog and Z prog
