Using a hammer and a handheld die, one can stamp a letter or numeral into a metal surface. Sets of alphanumeric dies for this purpose are widely available (example). When two or more characters are to be stamped, it can be tricky to get the impressed letters to be uniformly spaced and horizontally aligned.
I made a device to support this process. It consists of a grooved Spacing Template and a Block that slides over the Spacing Template. A pointed Screw projecting downward from the Block engages the grooves of the Spacing Template, so that the Block can be moved along the Spacing Template in discrete steps. A groove in the front of the Block aligns the die.
I milled the stamping guide from 6061 aluminum. Most of the dimensions are non-critical, except as follows:
To use the guide, I clamp the Spacing Template to the work and then move the Block along it, letting the point of the Screw fall into successive grooves.
