Hey guys, these expensive lathes all take piecework. you take the piece in, they make a wood or composite master, and you tell them how many you want.

Fascinating comparing the hand-spun method vs the machine: the spinning by hand is almost hypnotic to watch; the machine spinning is much less engaging.
I have six locks on my door all in a row. When I go out, I only lock every other one. I figure no matter how long somebody stands there picking the locks, they are always locking three. Elayne Boosler

It would be nice if there was a cup spinner that would let you watch as "your" cups were spun. The Silver Dollar City amusement park at Branson, Missouri has an antique wood duplicating lathe powered by steam. You can watch while the lathe makes you a keep-sake baseball bat (final touches by the craftsman operating the duplicating lathe.) I would gladly pay extra for a set of cups to be able to watch.
Magic is where you find it.....

I wonder if it would be possible to spin cups from damascus steel, that is a steel plate with a pattern based on the way nickel has been welded into it. Javanese smiths can achieve amazing designs in this material. I don't know if it would survive the forces created in the spinning process. Using arsenic trisulphide, it is possible to bring out the pattern in a very striking way.

Most work in steel is done on a machine similar to the CNC version, but much more heavy duty, usually augmented with hydraulics to move the metal. What they didn't show you on the videos was the annealing process. Most metals, especially of the non-ferris variety, need to be annealed every so often to relax the metal from work hardening. Work hardening is when the metal has been flexed so much that it becomes hardened and brittle. By heating copper or brass and allowing it to slowly cool, the molecules in the metal will relax, allowing further work. To not anneal is to court problems such as wrinkling or tearing. I have spun small items in both copper and brass, but am only a beginner. Check with Sorby tools - they make a nice set of spinning tools. You will need a wood lathe as well. |

They polish everything from small objects all they to stainless steel tanker trucks. It's an amazing operation. You have to be careful with CNC spinning. If the vendor is not using an annealing process your material is likely to crack over time. Jeff Busby's brass Paul Fox Cups, I've had a lot of sets come in for repair because they were done on a CNC spinning lathe but never annealed in the process and are spun too quickly.
