>>> The upright stretcher portion has 6 splines/ segment which provides for a smoother and rounder stretching of the rings with less stress on the mechanics. <<< 

Comes with a reducing plate with 16 depressions round that are smooth finish. 

Note: Care must be taken whenever stretching a rings, especially with stone set rings, thin shanks, inspect for any solder joints that may break apart when stretching. 

Tool works well with Bands, may need to anneal to soften the ring to afford expansion of the metal. 

When stretching it is better to stretch slightly then rotate or even flip the ring upside down on the spline and stretch again. 

The same is true for band reduction on the base plate... this method will provide and give a more even expansion. (Slight pressure at a time).   

***Generally this tool fixture will not expand more than 1 finger size.

NOTE: Miss-use of the Tool may result and cause damage to the stretching 6 segment spline, instructions included.   If you have any questions on how to use the stretcher and need any assistance call or contact us.

NOTE: Color will vary present stock is Blue --- not Grey as pictured.
