*Medium mandrels projected to ship by early December 2024. You can still order full set and we will ship S, L, and XL now , then when the medium arrives ship the medium.  Or you can purchase the other sizes separately and we will give you a discount on a future medium mandrel purchase. 

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.
