This is a lettering machine for stamping parts I made up. Table is 4" wide and 12" long. 1/4 20 holes in it. Thread is 3/8 16. Ram is 1 1/4" rack and pinion drive with an automatic punch built into it. Nose is removable for different sizes stamps. Right now I can use 1/16" and 1/8" stamps. Rail is bolted down and has a vee on top for round parts. I can use small strap clamps or double faced tape to hold parts.
