You can also use the FWBW0 for making bullseye pins. Stack a small one on top of a big one and peen. Particularly after you buff them together, which rounds the edges and smooths them out, it looks similar to one of the old bullseye pins. I don't care for the FWBW0 at the pivot...they're too thick to me. I prefer the .062"IDx.188"ODx.010" thick phosphor bronze ones I get from smallparts.com. That's just a preference thing, though.
