How to create your own pinstems for brooches

By Helen I. Driggs

I make my own pinstems for brooches using durable brass, nickel, or steel piano wire. The downside of working with a durable metal is that it’s time-
consuming to bring it to a fine, symmetrical, and sharp point. I normally swear by snap-on sanding discs for my flex-shaft for their speed and convenience during the clean-up phase of metalwork, but they don’t work in this case. Instead, you’ll need some good, old-fashioned center-punched sanding discs and a compatible screw mandrel to get this job done.
