.........bought some 18kt gold to roll into bezel wire. Does
anyone have a tip on how to efficiently do this?
G’day (again) Dave; I too can’t afford much high carat gold. But
my method for making bezels in silver is to use fine silver
preferably. I have cast it using 5mm x 6cm rod moulds (home made
of course) then roll the rods down to 2-3 mm square wire
with the vee-grooved rollers.(using a borrowed mill!) I then roll
the square wire down to 2 - 3mm x 0.5mm strip. With appropriate
annealing of course. However, I find it simpler these days to buy
2mm x 0.5mm fine silver strip from a NZ supplier. Surprisingly
cheap. Use a similar method for gold.
If you want to purify gold, you can cast the scrap to a rod,
button or some suitable shape, then using a cyanide bath (not the
same you used for the silver!) plate it on to a stainless steel
strip from which it is easily scraped off. Re-cast the fine
gold, make square wire of suitable size, then roll it to strip.
