JUST got this today: a Swanstrom disc cutter, and a couple of pattern plates suitable for my rolling mill. Here's the first results. I like 'em, and I didn't even tighten the mill enough. Another major benefit: the disc cutter is so precise that the amount of grinding is going to be minimal. My hands will love me. Oh yeah, the quarter is provided for scale. The cutter has ten sizes of punches. This one's the largest.
