Experience twisting different hardness wires?
Yes I have.
I got round this problem by using 2 wires half the thickness of the
harder wire twisted first, then twisting this initial twist with the
For example, most probably my most successful design of twisted
metal finished up as follows.
2 ni/ chrom wires of of 50 thou twisted first, the white colour, laid
along with 1 off 10% ali/bronze wire, the yellow colour, 100/000 th/
in annealed then 2 off phosphor bronze also of 100/1000 tho, the pink
colour. also annealed.
All 36 in long. Going round the bundle you have the white pair, then
a pink then the yellow then the pink.
Wind some scrap iron wire around one end, clamp in the 3 jaw chuck
in the lathe on slow speed.
the other end also bound with iron wire.,also held in a 3 jaw chuck
on the cross slide.
Power up the lathe and let the cross slide move as the twisting
When the twist is at the right no of turns per 12 in. Stop.
Unchuck, anneal, pickle, and its ready for the next operation. This
changes the shape from round to either half round, square, or oval
depending on its final use.
For wires half this thickness I twist up by hand, using a carpenters
brace on one end of the wires and the other end held in the leg
Smaller still, I have a hand drill with a 1 to 1 handle to chuck
ratio to do the twisting.
The only way to really find out if your plan for gold and argentium
will work this way is to give it a try.
Id be inclined to hard draw the argentium and fully anneal the gold.
then do a simple hand bend test.
your hands, with experience should be able to tell if the hardness
is near enough to twist up without failure.
Also you will need to make a reasonable length, ie 12 in or so.
Let us know the results of your experiments.
