Construct a sleek & seamless hollowform bracelet

The shape of gaskets used in engines inspired the original cross-section of this bracelet. I departed from that a bit when the design moved into the third dimension, but I really enjoy a clean, industrial design. This advanced-level fabrication project will challenge you to work large (and avoid warping), measure accurately to ensure all pieces fit together perfectly, and push your hinge-making skills as you learn how to make a hidden clasp and hinge that secures the bracelet with a snap!  by Alex Lewandowski
