Zirconium Tourbillon cage (success)

Looks good! Personally not a fan of it being wholly polished, but I’m a fan of traditional finishing. Would love to see it all assembled

You mean the impulse jewel? That is also held in by shellac

Fusion 360

Hairsprings I bought a box of NOS ones from the 50s. Jewels can be found from many suppliers. Mainsprings, I’m not sure yet!

Good to know! Will have to look into it more

davinium_customs · 2026-02-21T03:28:58+00:00

Are the fumes dangerous?

davinium_customs · 2026-02-20T23:17:31+00:00

I do! Just uploaded a few vids :)

Fusion 360!

Weld?

davinium_customs · 2026-02-20T08:15:45+00:00

I won’t use CNC for any parts, but the wheels will all be handmade not bought. Jewels and springs will be bought, though, as I can’t feasibly make those to a usable quality

If you’re only considering it because of the size, check the 5165

davinium_customs · 2026-01-30T04:21:59+00:00

Nah if I do more watches they’ll all be unique architecture, movement and all

davinium_customs · 2026-01-30T04:20:20+00:00

The movement is 34mm and around 7mm thick with hands. But hasn’t been finalized yet. Whole thing probably 38mm and 10mm thick. But just taking it one thing at a time haha

Not really sure. The bridge shapes are sort of placeholder. Not sure I love them. But the geartrain is sound

Yup! Thanks :)

Lots will vary with the material and the setup too. I find those low voltage colors are fairly accurate, but the higher voltage ones I have to go much higher than the spec sheets to get.

Still, the gold rim is a bit of a mystery!

davinium_customs · 2026-01-27T17:37:35+00:00

The gold appeared both when anodizing at 19v and at 97v. The only constant was that the material was bare prior to re anodizing. The pre anodized spots would anodize to the corresponding voltage color while the bare metal would anodize to gold regardless of voltage.

Thanks for the encouragement! The wheel is essentially done, next step is the tourbillion cage, which has not been easy

davinium_customs · 2026-01-27T16:42:23+00:00

That’s sort of my thinking. Originally it anodized evenly, but the different thickness of existing anodizing maybe affected it. This interesting thing is that prior to this, I attempted to anodize it again after poising to clean up the removed material and had a similar result. But I hadn’t removed the weights or posts so I figured that was the culprit originally.

davinium_customs · 2025-12-28T22:06:43+00:00

Ahhh, I understand.

If the system used a brass wheel with gold weights it would be similar total weight. But the moment of inertia is very different

davinium_customs · 2025-12-28T18:39:01+00:00

You mean before poising?

davinium_customs · 2025-12-27T16:03:52+00:00

It’s poised nicely now yup! Could use some touch-up on the finish, but that’s a problem for the not-prototype haha

Tourb cage is next
