Wild idea or not for 15 inch trim rings?

[Skdmark]

What if you took a plain 15x7 3 inch deep trim ring and ran it through a bead roller to create a proper outer edge detail?

1. Find a plain stainless trim ring that fits and has an oval valve stem opening.
2. Get a custom set of dies made for a bead roller
3. Make a fixture to hold the trim ring
4. Run it through the bead roller
5. Repeat

Maybe: You'd also have to build a guide so the ring rotated perfectly while rolling the bead but that wouldn't be too hard. Another trick is finding rings with the correct convex profile leading to the center as well. Unbelieveable no vendor will make correct rings, everyone needs 4 of them.

Not sure it would work without further modifications and tools. Reason being that trim rings are not a single wall thing. They have dual wall and any die work you did to the exterior wall would either deform the inner wall or require it to be removed first.

The fixture I have in mind would have a free spinning base with a raised tapered lip around the periphery that the ring would nest into. Then, use a tapered plug to drop down the center and clamp the trim ring firmly to the base. The tapered plug would have a pin out the side to key into the valve stem hole on the trim ring. Using the pin through the valve stem hole would mechanically lock the ring into the fixture and provide a repeatable locator.

To your point about the profile to the center, I'm wondering if the fixture base and clamp could be used to correct that.

I have seen others discussing techniques for removing the inner wall / retaining ring to get at the backside of the lip for dent repair.
That's something that would most certainly need to be done.

The trim rings would need to be annealed first as they are hardened and would most likely crack before you could bend the to whatever profile you were trying. Too much trouble unless you want to market them and make 100's to re-coupe tooling costs. Probably better to approach a Taiwan company about making them for you.....
