Is there anyone who could provide the dimensions for a punch used to make bullseye washers. I found a thread where ScienceGuy made one that produced nice washers, but I didn't see anything about its' dimensions. I know the bullseye washers were not all the same size, but it would be helpful to know the dimensions of a punch that someone has used successfully. I'm hoping I can eventually have a machinist make one for me, so I'm trying to get the information that they would need.

Also, a question about how the original bullseye washers were made. Were the punches used by cutlers of the time also made with a protruding shape on the end, or were they recessed?

Thanks
