The ring, now with lugs attached, goes back on the lathe. Since I'll be cutting the outside of the watch I put the clamps on the inside of the ring.

The lugs all need to be the same size and join the ring smoothly at the top and bottom without any excess material overhanging. First I cut the lugs all to the same length with the above lathe set-up. The cutter, making moves towards and then away from the work, gradually gets closer to the lugs. Eventually all the lugs are the same size.

Next I set the lathe bit to cut the front face to make the ring and the lugs the same height

.

Then I used the compound slide to cut the lugs at a 10° angle. The compound slide allows me to adjust the angle of the cutter and also gives me an additional forward/backward motion control at the given angle.

.

I don't have any photos of the next thing, but I took out the watch section ring and turned it around and did the same thing for the back side, only this time cutting the angle as the lugs are coming towards the cutter, i.e. 10° measured anti-clockwise.

Once done the ring looks like this, with the solder joins not visible at all

,

and the reverse side looks like this:

It's starting to look a little bit more like a watch now!
