The Ultimate Set includes all four highest-quality, stainless steel Expanding Ring Mandrels and a hex key.  It serves the full range of common ring sizes and offers significant cost savings. 

These Expanding Ring Mandrels were custom-designed by Patrick Adair to meet a ring maker's special needs.  The varied steps offer plenty of space to work on many styles and sizes of rings.  The expanding aspect of the tool holds a ring blank securely, allowing for a high level of precision during all phases of ring making.  These mandrels withstand sanding abrasion much longer than regular steel and will not rust.  Each shaft is 1/2" in diameter and is designed to work in a lathe or a drill.  The length was kept short so the full tool remains true while spinning.  

1. Small - Recommended for sizes 4.5, 5, 5.5, 6, 6.5, 7.

2. Medium - Recommended for sizes 7.5, 8, 8.5, 9, 9.5, 10, 10.5.

3. Large - Recommended for sizes 10.5, 11, 11.5, 12, 12.5, 13, 13.5 

4.  Extra Large - Recommended for sizes 13.5, 14, 14.5 15, 15.5, 16.

Can’t really pinpoint anything I don’t like about these. All my feedback is positive. They’re so great to use and it’s allowed me to streamline my process of making rings.

Works perfectly

Does exactly what it was intended to do. I have made a few rings on the largest mandrel and it seems to work perfectly.
