How do you make half round wire

Pulling two wires through a round plate, as opposed to one wire through a half-round plate gives you a lot more half-round wire for a lot less work ;-).

This is a very easy and clever cost effective solution…thanks for letting everyone know…I’ve used that technique too… for very thick half rounds, like for a ring shank, I don’t think that can be done without a half round rolling mill, which I don’t have.

Any solutions?
