Metal spinning, a technique for using a lathe to create metal
shapes, is sometimes used to create large stainless steel bowl and sink
molds. This is a complicated and expensive process, but
it has the advantage of yielding a slump mold that is extremely
strong and durable.
The basic metal spinning process involves shaping a piece of
metal that has been mounted on a spinning lathe. As the metal
spins, a tool is used to press against the sides of the spinning
metal and make it conform to a form that has also been mounted to
the lathe. Shaping the metal is a gradual process that's been called an "art" -- it requires a strong hand, a deft touch with
the tool, and a careful eye.
As complicated as this sounds, it's further complicated by the
fact that the best slumping molds are made from stainless steel, one
of the more difficult materials to spin on the lathe. Add it
all up and it's no wonder that good metal spinners are hard to find.
But they can be found. And if you're searching for a large
mold that you want to use many, many times, then it may be
worthwhile to track down someone with the necessary skills and
Part two of this tip continues tomorrow with more
on metal spinning large slumping molds.
