Just thought I'd pass this along. I've seen a lot of spring loaded engravers and I've been wanting to make one myself someday. Well today I had a "duh" moment and thought of my micro tapping guide!! I pulled it out, loaded it up in a collet, and away we went! The plunger is tight and has a beautiful slip fit (for now lol!) and has a very strong spring as well. I did not turn the spindle on for this.
I set it up to take .002" and used 2 passes and it really works VERY well. Here's the link to the actual product:

Sorry about the pics, but I figured you could get the idea.
