I found this gear on the side of the road a few months back and placed it on a shelf in my shop. After looking at it for some time I had the idea to press it into a block of hot steel to see what kind of impression it would make.
My small hydraulic press does not push hard enough to work on this scale and so I brought this to the Crucible last night to use their 15 ton press. It didn’t give me the depth I was hoping for, but it still looks pretty cool. Now I have to find access to a press with more tonnage.
