The wedding band: milling titanium and wrapping it in palladium

You’ve got to admit that custom milling your own wedding band is pretty hard-core. In this case [Jeremy Swerdlow] is making it for his friend, but that doesn’t diminish the fun of the project. After the break you can watch him mill a titanium ring and wrap it with a palladium inlay.

To solder palladium to titanium [Jeremy] would need special equipment, so he found another way to mate the dissimilar metals. He milled a dovetail groove in the center of the titanium band. To do that, he had to make a special cutting tool that was just the right size. Once had milled the ring’s rough dimensions, he had to fabricate a custom mandrel to hold the ring for the rest of the job. The dovetail was then filled with a palladium strip using a combination of heat and hammering. The two ends are soldered together using palladium solder. The ring in the middle shows this solder joint. To the right is a ring after the inlay is milled flush but before the final polishing which will bring out the best qualities of both metals.

If you don’t have the machine shop skills to pull this off you could always try your hand at 3d printed rings.
