Got a small wheel and have been playing with it to learn. Smooths out
pounded metal very nicely. My question is this. When I run flat sheet
metal north-south through the wheel, I was expecting it to curve in the
east-west direction. However, it curved north soouth. Obviously I'm
confused about the direction the wheel stretches the metal. Am I doing
something wrong or is this correct? ( I can't see any other way to do
it )
. Could anyone explain this to me?

A second question also. What is it called and how do you do it - fold
over
the edge of the sheet metal to form a rolled over edge that exposes a
rounded smooth surface?


Thanks

To answer your second question first. There are 2 types of folded edge. The
one is just a 180 deg fold which gives a nice rounded edge to the metal. The
other is where the metal is wrapped around a wire. This gives a greater
diameter to the rounded edge.
With your wheel, you are pushing the metal along in front of the wheel and
stretching it that way rather than forcing it out sideways. Try rolling
pastry or plastacine to see the effect. You aren't doing anything wrong.
I would add that my experience of wheels is Very limited and others may know
better.
