I just completed my metal stamp guide which I semi-copied/stole from a YouTuber. It allows infinite spacing between characters and keeps the stamps vertical.
I used a 1/4-20 threaded rod which gives 0.050" per revolution of the handle. I used my dividing head to mark 10 spaces around the wheel giving 0.005" resolution (which is overkill, but I did it anyways).
Ready to stamp.
