Some members of the community asked about this tool from my video carving a ring, so I thought I’d post about it separately. This was created by @grstools and it’s a mandrel that has equidistant lines which allow you to mark a ring. I find it really helpful and they are available from many retailers. If you have a different way you measure on a ring send me a tip please! Tips@metalsmithsociety.com #grstools #ringmandrel #jewelrytools
