I was watching "How it's made" last night. A guy was making a copper bowl. He had a blunt ball of sort on his lathe and had a copper disc at the curved end of it. With the disc spinning, he used a blunt rod and started stretching the copper over the ball. The copper stretched around it as it was spinning. It was pretty interesting. Another use for the lathe.

metal spinning has been gaining popularity for the past couple years.

Oneway even has a section on their website for it.

I've done a bit of metal spinning, I'm not very good at it, but can make some simple pieces, it is a whole different way of working with metal, not like turning wood at all really, but yes lathe work.

Nowadays they use lathes/machines with hydraulic powered spinners and rollers to do the spinning, goes much faster and they can do heavier work also

If you are thinking about trying this, consider spinning pewter rather than copper. Pewter does not work harden like copper. The copper usually needs to be annealed a couple of times before a piece is complete. This just adds a complication that you won't have with pewter.

Neat concept, but like some of the others - looks like a costly diversion!! More toys, more materials, and then.....what do I do with all this wood I have accumulated?!?!?

Leo, neat ornaments!!!

I also saw a movie program about 6 months ago or so on this subject. Looked very interesting.

Just as long as the copper didnt come apart and start flying like some of my wood does everything would be fine.

Also can you imagine what a sheet of copper would cost these days.

408 Metal Spinning Redemption: Famous for his lack of skill when it comes to metal spinning Tim redeems himself by making a simple nut dish. Then master metal spinner Tom Farrell drops by the shop to spin a spectacular lidded candy dish.

Saw this recently...sure doesn't look too daunting. They used aluminum, and made a point to talk about difference between alloy and pure aluminum. You want to spin with the ductile pure aluminum. Easy way to tell difference is that it bends easily and doesn't tend to rebound it's shape.

I have seen a demo on metal spinning and always wanted to try it. Dave Hout does some metal spinning.
