Corn Popper?
I had to laugh at myself, I was up in the middle of night, and checked the Forum, with sleepy eyes, I thought the post said "Corn Popper". I opened it up and couldn't figure out how in the heck you could pop corn with it. Then of course, my eyes cleared and I laughed out loud.
Nice metal work, but I would sure be careful with File-Steel because it could sure cut the daylights out of a sweet coin or ring. If the concept works, maybe Brass would be an improvement. Just a thought.
