Making my Wedding Band (May 2017)

I'm getting married in June, so here's how I made my wedding band. Just like with the engagement ring and the ring box, I filmed the whole process and made a short video. This was a really easy project and I didn't bother making a detailed CAD drawing. It's 1.000" OD, .850" ID (size 12.25), and 3/16" thick. I ground a lathe tool to put a .100" radius on the ID and a .300" radius on the OD.



I started off with the same bar of titanium I made my wife's ring out of.

Then I faced off the end to get a nice crisp corner.

Next I turned the OD down to 1.000" so it will fit in a 5C collet later on.

Next I hogged out most of the waste on the ID with a 3/4" drill.

Then I came in with a boring bar and took the ID up to .850" (size 12.25).

I needed to put a radius on the ID and a nice sweeping curve on the OD, so I ground up this 1/4" lathe blank. The smaller radius is .100" and the larger is .300".

Next I radiused one side of the ID on the ring with the .100" radius curve.

That's about all I could do in this setup, so I parted the ring off so it was 3/16" thick.

Then I stuck it in a 5C collet and radiused the other edge of the ID and polished the inside with some really fine sandpaper and steel wool.

To work on the OD, I turned an expanding mandrel down to tightly fit the ID of the ring. It usually takes me a lot of finagling around to get things running true on these kinds of mandrels. Especially short stubby cylinders like this.

Now I could use the .300" radius side of my tool and put a nice curve on the OD.

Form tools often don't leave the best surface finish, so I polished it up with some sandpaper and steel wool.
