A friend on the Metalmeet site asked me to show how to form a copper vase out of a piece of copper tube.
Tutorial index, go to page: 1 - 2 - 3 - 4 - 5 - 6 - 7
Above is a photo of the tube after having made the first shrinking pass on the neck of the vessel.
Above is a photo showing the contact angle used for stretching out (sinking) the sides of the vessel.
Below are the first and second passes rotating the piece under the hammer.
I got carried away and started stretching before I did this. I should have shrunk the bottom edge a bit before starting the stretching of the sides. Above I am raising.shrinking the edge of the bottom of the vase. This will work harden it as well as make it closer to the dimension I want.
When you are beating on the side with the rubber hammer some blows use the edge of the piece as a fulcrum and the pressure bells it out. IF you shrink the bottom edge first it work hardens so it holds it's shape better.
This is a shot of the shrunk (raised) lower edge.
The stake, vessel, and a rubber hammer.
The piece is moved under the hammer until you have hit and stretched all the surface that you want to at least once.
