Texture the outside of the bangle as well as the top and bottom. If using a texturing hammer other than a domed face one, use the domed face hammer to stretch the metal until it is at least halfway to the desired diameter. There will be less chance of splitting the bangle that way. A Sharp Raising Hammer does not move or expand metal as fast as a domed face hammer. The bangle also gets larger faster when hammered on a bench block. Check the size often.
Hammer out to an inside diameter of: XX-Small: 2¼" X-Small 2-3/8" Small 2½" Medium 2-5/8 Large 2¾" X-Large 2-7/8"
Pro Tip: Measure the diameter with a clear ruler both horizontally (shown) and vertically until the desired size is reached.
Pro Tip: When making multiples, slide a finished bangle on the bracelet mandrel. Use a fine point Sharpie marker to draw a line above and below it. It will then be easy to tell when the bangle is getting close to the desired size.
