Hey Duane,
The tool is actually meant for soft materials like aluminum, copper, silver and etc. You're correct that you slip the material in the thin slot, position it where you want the hole and if it's soft material, a BFH works great. They don't recommend using it on steel, but so far, it's worked great. I use a light coat of oil on the sheet metal and set everything up in my press. It pushes the punch right thru the metal and then I use a rawhide hammer to tap the coin and the punch out the other side. Only reason I do it this way is I was afraid it might hose up the punch if it caught an edge. Pushing it thru with the press seems to allow it to find its way.
