Pancake punch

Post by sawdust1 »

Has anyone ever cut a pancake punch? My question is about kerf, how much is too much? I have about 1.5mm kerf from my torch. I suspect that tolerances are related to what you are cutting.

If anyone has tried this I would be interested in hearing about it.

If you google "Metal Pancake Punch" you'll get pics of a tool that uses a pattern cut in steel used to "punch" thin copper and other thin materials like possibly leather, to use for mostly jewelry

Thin materials require almost no clearance at all. You would need to cut the die, then cut the punch with a different drawing, you can't use the drop from the die as a punch. way too much clearance if you do. Might work on leather, or thick fabrics? I don't know, but won't work on sheet metal.

I did build it finally. I did use two separate drawings and cuttings. I am punching quarter inch ABS plastic, it works well enough though it rolls the first 1/32 of an inch on the top. If I decide to improve it I think i will use a milling machine or lathe.
