I’m trying to derive ear wire from a leftover casting I made using
sterling from IJS a long time ago, so I know I am proceeding with a
I had no trouble rolling the wire through my rolling mill all the way
down to its finest setting, but my wife considers the wire still too
thick for her ears, so I decided to try out my drawplate with carbide
ties for the first time.
I clamped the drawplate in a vise bolted to my table, sharped one end
of the wire to a point, lubricated it with EVOO (I can’t get beeswax
on it), and fed it into the metal side of the die with it existing
from the carbide sid, pulling with conventional drawing tongs which I
bought for the purposes, and annealing every few passes.
I’ve been successful all the down to the 0.80 millimeter diameter
die. But no matter how hard I try to sharpen the end and then anneal
afterward, I cannot get the wire through the 0.75 millimeter die at
all. the point snaps under the tension.
About the only thing I can think of offhand is sanding the entire
wire to bring the diameter down to where it can all just go through
the die, but I think that would be overkill.
Any clues on how I can overcome this hurdle?
Thanks in advance,
