Middle and top bowl together
July 15, 2002
These are the two pounded parts of the bowls together.
It's so lovely to me it makes my heart skip a beat!

Work day with John D.
July 13, 2002
John came over for a work day saturday.
We played with the top bowl on the life sized model,
and cut the walls for the middle and bottom bowls.

Top bowl wall is now half done!
June 25, 2002
I welded in the rest of the top bowl wall.
Now all that's left is welding the lip and pounding it!

Welding the top bowl wall to the bottom
June 21, 2002
Here's the final welding of the wall to the bottom of the top bowl.
I burned a couple holes -- esp. near the old cracked welds.
But these filled in okay.
I had a little trouble with one big hole, nad filled it
with a piece of copper -- but the piece melted into a blob
before it could weld as a whole, but the blob eventually filled it in.
The walls came to something *less* than four 3' pieces --
meaning less than 12', meaning less than 4' times pi...
But the inner circle part [the top of the top hat]
is slightly smaller, and when I realized that a 2.5" lip
meant subtracting 5" from 4' -- which is over 15" from the 12' --
this made a lot more sense.
Now all that's left is welding on the lip...

pounding the top bowl
June 18, 2002
This was an intensely spiritual thing!
I'm not typically into that kind of thing,
but while pounding I could *feel* my ancestral women pouding grain...
I couldn't get away from it!
It was like the intense feeling of drumming.
Totally captivating!
You can see it on my face...

Top bowl pounding platform
June 16, 2002
This platform is what we'll be pounding against.
It will help shape the bottom rounded part of the top bowl.

Piecing the top bowl copper together
June 2, 2002
Took a sheet of copper to Greg's house to make a 4'x4'
sheet for the top bowl.
The welds are terrible, but, hey! it was my first real try welding copper!
When I went back later to clean up the welds,
I had a lot of trouble with cracking.
I realized that the more I welded over the area,
the more the crystals lined up,
and the cracks were along crystal lines.
So I solved it by adding more copper [confusing the crystals]
and annealing, which only involved spraying the copper with water.
These two things seemed to solve the problem!
All in all, I was quite happy and learned a lot!
