The JDG ring Crafters mandrels, made from stainless steel or delrin

JDG ring Crafters Mandrels are a perfect fit for ring makers trying to get started at a lower cost than our premium stainless steel JDG Pro expanding ring mandrels. 

Available in 2 sizes and materials, laser engraved with sizes on each step for ease of use. ( refer to SIZING chart for international sizes)

These mandrels are great for work holding rings and round objects for turning, 1/2 inch shaft sizes for easy lathe mounting.

Collet morse taper chucks available separately 

A small lip is machined on the last step for ease of ring mounting to get a secure grip. 

Over expansion will affect the run out and may cause damage to the mandrel. Tension should not be kept for extended lengths of time and released when not in use to provide optimal life to mandrels.

Care should be taken when using water and solvents always wipe off the mandrels when not in use.

Delrin mandrel should not be used for rough turning as they are made for glueing and finishing only, as delrin is a softer material that will wear down faster than metal, a black powder may come off the delrin mandrel when sanding. 

These mandrels are consumables and should be replaced when worn out, show signs of extreme wear and/or broken, replacement screws are also available.

Always use appropriate eyewear and PPE when turning or using tools.
