Question 1

What is a mandrel?

Accepted Answer

A mandrel, or triblet, is a long, thin jewellery tool with a tapered end. This shape makes it ideal for using in a variety of different metal forming projects. However, mandrels come into their own when shaping or resizing rings. So whether you need a hand with creating rings from scratch or you’re looking to offer ring resizing as a service, you’ll need to pick up a mandrel.

Question 2

What is a mandrel used for?

Accepted Answer

There are a number of different ways you can use this tool, including: 1. Measuring ring size. This is a quick and easy way to gauge a customer’s ring size by using one of their pre-existing rings. 2. Creating rings from scratch. A key part of the ring making process is shaping, so mandrels are perfect to help you bend the metal into shape. 3. Resizing rings. If a ring is a little on the small side, a mandrel can be used to increase the size of the band by at least a couple of ring sizes.

Question 3

How to use a mandrel when creating a ring?

Accepted Answer

The process of using a mandrel to form rings is very simple. Once you’ve soldered and pickled the metal, all you need to do is: 1. Place the strip of metal on the mandrel so it aligns with the correct size. 2. Continuously tap the metal with a rawhide mallet until it starts to take shape. 3. Every so often, take the metal off the mandrel to assess the shape, swap sides and continue tapping until it is even on both sides.

Question 4

How to stretch a ring with a mandrel?

Accepted Answer

Just follow these straightforward steps and give it a go yourself: 1. Make a note of the current size of the ring. Then, protecting any stone settings with your finger, place the ring onto the mandrel. 2. Hit the back of the ring with a rawhide mallet (any other hammer will mark the metal) and continue to do so while directing the strikes downwards. 3. Repeat the action on the other side of the ring, frequently swapping sides to guarantee an even stretch. 4. Refer back to the original size of the ring and keep checking until it becomes the desired size. 5. To finish, use a Dremel tool with a polishing wheel attachment and some rouge to enhance the shine.
