Wax Ring Design Kit

Specially designed for working with wax models, the mandrels in this set are sized to allow for metal shrinkage during casting. Pre-sized ring blanks fit easily and securely onto smooth sleeves while you work on their exteriors. The holding fixture lets you work hands-free. Clearly marked to help you easily find the sizes you need with no time wasted.
Precisely machined, stay-cool aluminum ring sleeves allow you to approach your work from any angle.

Set includes full and half sizes from  US size 4 to 13.

Please note: The ball bearing that holds the aluminium ring sleeves can be adjusted higher or lower using a 3mm allen key (not included). This will make the ring sleeves looser or firmer
