If you have or plan to have a CNC mill that will come in handy.

Use one like all the time to zet my Z-Axis Zero. While I am using a CNC, I don't see why it is not just as useful to set the Z-Axis zero point for manual operations as well.

Yeah, I'll give it a try.
So you touch off with your tool on to the gauge. When the light goes off you look the quill. Then you know you're exactly two inches for the work. Moove the knee up accordingly.?

A tool setter, use it since you already have it, think of if it as a contact edge finder for the Z axis, it is no better or worse then any other method, if you use a good deal of solid carbide mill tooling it will help.

Many home shop machinists have never used a machine that has no handles or mechanical hand wheels connected to leadscrews and have never experienced the joy of running a tool into the part with a jog button (-:

I hate to admit it but I am on my 2nd one of these after "Jogging" the wrong direction after touching off. It has quite a lot of spring based movement to allow for that type of mistake but everything has a limit :apologize:.

Very true. And even with handwheels, there's the possibility of chipping or otherwise damaging the cutting edges of a end mill (especially carbide) - or affecting the surface of the workpiece - when touching off. Here's an article by Rick Sparber (a forum member) illustrating a safe alternative way to get a Z reference:

Enjoy!
