Bronze Anti-Stone Chipping Tools made by your self
First of all, I want to apologize because of my English (Spanish is
my main language), I’ll do my best anyway.
So, I wanted to share with you guys what I happily discovered trying
to make a prong pusher and a burnisher for safely fixing the stones
in gypsy setting.
After chipping some sapphires and rubies with a steel burnisher and
pusher, I finally pissed off and decided to dedicate some hours to
make my own tools out of bronze.
I found a very simple recipe used for jeweller’s punches which is:
Cu - 83,3 parts & Sn - 16,7 parts.
But out of my expectations I had a LOT of trouble when rolling it,
it always cracked! I tried different annealing temperatures,
quenching methods and so on, without success after I discover that
annealing to a dull red, quickly quenching and rolling ONLY one pass
per side in the rolling mill’s grooves each time, was the way to do
So i guarantee you that following those steps you will be able to
make your own “Safe Bronze” tools.
Hope it helps.
