what is the preferred hammer when forming D shaped rings on mandrel?
What seems to be the preferred hammer when forming a D-shape on flat
rings while on a mandrel by hitting the ring towards the edges. (Such
as making a wedding ring) I know that some people can make this shape
by hand rather than using half round rollers. Are the using forming
hammers, ball peen, etc?
While we are on that subject. I also am curious about the method of
forming half round wire with a flat rolling mill by putting copper
plate between one side of the round wire and then running it through
the rolling mill. I read about that but there was no mention of how
thick you should try of a copper plate. I assume the thicker the
copper plate the better it will preserve one side of the roundness of
I have a large Durston rolling mill that has plenty of square wire
rollers and flat rollers but no half round. I was wondering the
different ways I could try at forming D-shaped wire, (for rings).
