Hi Betsy,
Earposts are one of the easier things to make. If you have a
rolling mill and drawplate it can be done in a matter of minutes.
Melt some gold and put it through the rolling mill until you have
a size that will fit through the drawplate. Then put it in the
drawplate and pull it through until you have the right size wire.
Cut it to the length you need and you are done.
Best Regards,
Bill Raby
