I took some photos while I was visiting Jim Rimmer in BC Canada to learn about casting metal type after TypeCon. They are here:

Here's a sample:

This 'a' is from the monospace I had critiqued at TypeCon.
I found the experience fascinating. All the materials awareness is amazing. The wrong brass. Your done. Wrong mix of Lead, Tin & Antimony. It's over. Done. It goes on & on. There are so many ways to go wrong. It really shows you what was involved in getting superior printing. The machines themselves are amazing too. They are hugely precise - to the thickness of cigarette paper, 1/1000th of an inch. And Jim was a very very nice guy.
Thanks again Jim!
Here's hoping you will be at TypeCon in Buffalo.
