Review on ✨ Complete 4pcs Ring Mandrel Sizer Tool Kit with Metal Mandrel and 27pcs Ring Sizer Gauge Circle Models - Perfect for Jewelry Making and Measuring by Linda Diaz

Very easy installation. Learning experience for me, I ruined the hammer without understanding what it was designed for, the ring mandrel is soft so using a metal hammer is not recommended, the finger size works great, as does the measuring tool, I use these tools all day. I hope to be able to work with carbides again. I bought a hammer specifically designed not to interfere with the working shaft. My hopes were to make metal rings for my miniature wagon wheels. So unfortunately I messed up the hammer that makes rings out of coins, if I had made them out of a softer metal I'm sure the hammer would have done just fine.
