<p>[QUOTE="John Burgess, post: 7596234, member: 105098"]It's a bit more elaborate than a counterstamp. It's more along the lines of repoussè.

I think both sides are done at the same time the back side pushes metal up and on the front side it forces it back down like a mold to leave the impression. I have an old hole punch tool that works like that with an Allan key on sheet metal you drill a hole and sandwich the sheet metal between the two dies and screw it down the bottom and top cut at the same time and punch out a circle without bending the sheet and leaves clean edges. It must be something along the lines of this device...Maybe a clamp and vise to do it.</p><p><br /></p><p>The G is for geometry in the center of the measuring tools, compass and 90 angle square ruler.</p><p><br /></p><p>This is one of the nicer ones I've seen.[/QUOTE]</p><p><br /></p>
