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
