[TheForge] Re: copper bowls

[Bruce Freeman]

Jim,

Spinning sounds like a good idea, but those are rather
large to try on your own.

Be aware that bowls such as you are describing are
(were?) available commercially for candy-making. 
(Some may be floating in the bayous as we speak,
having been washed by Katrina from the fudge shoppes
of New Orleans.)  I've been collecting the
kitchen-sized versions of these (now replaced by SS)
and have an 11"-er hanging in my kichen.  I can't
point you to a source, but candy-making seems to be
the common use.

A few years ago Peter Renzetti did a neat demo at
Gichner's Hammer-In.  He had a customer who wanted a
very deep copper vessel - maybe 8" across the top and
8" deep - out of fairly thin copper.  Peter TIG-welded
a ~6" disk to a second piece that wrapped up to a
truncated cone.  Then he hammered it into the final
shape.  Quite elegant, and a LOT less work than
sinking a sheet.  The trick was to use a wire that
matched the copper in color - and I can't advise you
on that.  (Peter would probably share the info.)

Best luck,

Bruce

I have been asked to make 2 copper bowls, half bowls
actually, for a 
wall
mounted fountain. One bowl has a 36 inch diameter with
an 18 inch 
center
depth; the other is 24 inch diameter with a 10 inch
center depth. Can 
anyone
out there spin something this large? Any other ideas
how to do this?
Thanks
Jim Pigott
