"Now, THATS a visual!"

When I shipped the press to Phil last week, I had no way to really test it. I aligned everything, but didn't want to put copper through the dies, as I knew that he was going to be making parts for the presentation at the Santa Fe Symposium. What I am trying to say, is that this is the first time that I have seen the results. WHEEEEE!!!!!

Dar, this is just another example of the clay-like properties of metal. By providing a fixed set of internal and external constraints, the metal has no choice except to flow. Depending upon where the last annealing is done in the sequence (not all of which were shown here), the tube can be extremely hard, or pretty malleable. The metal is incredibly compressed from all of the "forging", and will take a high lustre polish almost instantly. As the image shows, it is almost mirror smooth "as drawn".

Ever seen a mokume gane ring with a gorgeous pattern interrupted by a solder seam? Think seamless! How about cigar covers? Obviously, it probably be 18 or 20 gauge, rather than 12. It would already have the ends in place, it would be work hardened, and if the design was worked out carefully, with no soldering, it would resist denting in a major way! If making rings, simply slice off the length desired (like slicing a loaf of bread), and you have your ring stock ready to size.

Phil, after the tube is drawn, how many ring sizes can the 12 gauge stock be pushed?
