Now to my problem I am looking for a "1/2 round drawplate".
I’m sure others will point this out too but you might want to
consider the old trick of drawing two pieces of wire through a round
drawplate in order to get your 1/2 round.
If you have access to a copy of Charles Lewton-Brain’s “Cheap Thrills
In The Toolshop” he talks about doing this on pages 43-44. See also
Tim McCreight’s “Complete Metalsmith”, the section on “Wire Drawing”
(p.68-69 in the Pro Edition but it’s in the other editions as well).
I believe the other primary texts (Untracht, Brepohl/Lewton-Brain,
etc) offer similar info on this.
