Want to build a round bezel for a clock
I have an antique neon clock that is extremely hard to find parts for. I'd like to build a round front bezel that would enclose the neon and would also house the glass lens.
I envision the part to be a curved Z-section with 1/2" base leg, 1 3/4" standing leg and 1/2" top leg. Finished diameter would be about 26" and inner ID would be about 24". Material could be aluminum but preferably thin steel. I know I could flat-pattern this and do a welded assy but was interested in other options like bending up the section then roll forming and welding the end. I'm not sure if this is even possible without hand shrinking and stretching the horizontal legs. Any thoughts on this? I attached a pic of the clock to illustrate where the part is going.

I'd spin it on a spinning lathe.

You do not say what tools you have to work with . A cross sectional drawing of what you need would help . If it was the outer quarter section of a donut I would make a section of a 45 degree cone and reform it on reciprocating machine. This could be done in arbor or hydraulic press walking it through narrow dies . Ken

I have a 4ft finger break and a shrinker/stretcher. I'll see if I can draw up what I am trying to build.

If you had access to a bead roller you could shape/form something interesting

While it's a lot smaller in cross section than what you're planning, take a look at the bead roller work I did a few years ago on a Z section. Might give you some ideas. You'll need more rigid control than what I used to achieve a real good round shape.

Hey Bob - thats exactly the concept I was thinking of. Here's a pic of a smaller diameter ring as an example.
