Material: The RingToolStretcher&Reducer is entirely made out of hardened steel with a Blue painted base which is durable and wear-resistant.
Design: The highly polished enlarging ringexpandertool is placed on the top of the shaft, with the operating shaft next to it. It includes 4 pre-drilled holes for bench mounting and 6 segment splines mandrel with sizes(1-15) numbered on it. The reduction plate is reversible and has 8 reduction punches which can reduce the band up to 12mm wide.
Features: The RingStretcher and Reducer can adjust the size of any ring. It allows you to easily stretch and reduce metalrings and bands. The reversible, reducing plate re-sizes the ring shanks up to 12 mm wide by compression. The non-threaded handle can be adjusted with an exterior screw.
Function: First place the ring onto the stretcher rod, compare the size reading on the rod to your ringmandrel reading then slowly push the lever until you feel resistance, at that point very gently push the lever and flip the ring over and repeat. Check ring size frequently on your mandrel to avoid stretching your ring out too much. The same is true for band reduction on the base plate and this method will provide and give a more even expansion (Slight pressure at a time).
