I decided to make a fountain bowl out of one sheet , all forged instead of welding in the end.
It's a lot of work.

Laying out the pattern on the flat sheet. Note the arc drawn at the top of the sheet.
By the time the pattern is developed, that arc will be a straight line and the straight line that is set with the pullmax will be a curve.

The best part about having toys is when when you get to use them. Here I use my pullmax to set the back (wall end) edge of the fountain bowl

I started off by using a thumbnail shrinking die on the flat end of the bowl

I then used the thumbnail die to start the curve of the bowl end.

Copper work hardens rapidly and must be repeated annealed and quenched to make it soft enough to work.

Here is a progress shot, much of the shape as been defined but the flat end is still not deep enough. More shrinking is required.

This shows how some of the shrinking was done on the flat end of the basin.
Here is the finished blank, ready for detail to be added.
