The main piece of equipment I needed was a rolling mill.  This is a pic of me and my Rouselle rolling mill which squashed the silver billets from a thickness of about 1/2 inch to .0625 inches and increased the length from about a foot to about 6 feet.  We kept the rollers polished with diamond dust to impart a brilliant finish to the silver.

In the background is my small punch press that I used to cut the blanks that were made into the finished bar.
