The Fretz Spinner Ring Jig allows you to form smooth, symmetrical concave bands for spinner ring.
This innovative jig consists of a concave curved stamping mandrel (SRM-1) and two-hole steel faced block (SRB-1). The mandrel is designed to curve the band's edge one side at a time. The block supports the ring and lets the mandrel pass through as it is being flared with a hammer (sold separately).
- Hammer the mandrel’s end to gently flare one side of the ring.
- Count the blows so the other side can be done with the same force to maintain symmetry.
- Place the “spinner band” over the non-flared end of the band and repeat the flaring process to lock the “spinner” on.
