Jim,
What you need is a no zinc bronze. Bronze is copper alloy. Go to your
nearest machine shop and beg or buy a tiny piece of aluminum bronze and turn
it to your needs. SAE 94 bronze is softer and good. It has lead but no
zinc. All machine shops have left overs and will give you a little piece
happily with no sweat.
