An it-almost-worked experiment setting type in the round: I just couldn’t find a way to make the type hold (I need some sort of “expands from within” circular clamp, like the opposite of a pipe clamp).
Despite the failure, I was happy that I got this far; the result could have been lovely.

Mechanical clocks and watches
Mechanical clocks and watches have spiral springs of metal ribbon, so I wonder if you could find appropriately sized metal ribbon of similar properties and if that could be useful.

Why not use a pipe clamp and "open" it to expand the size?
My first thought exactly.
My first thought exactly. Except that pipe clamps have the big “clamping” mechanism sticking out one side, so aren’t round. I also though about simply turning a pipe clamp inside-out, and that showed promise, but renders the screw mechanism inaccessible.

Sounds like you want what I’ve seen called a spreader (bar) clamp, which I think is a fairly basic carpentry tool I’ve seen at Lowes and I bet you could find lots of places
I’m thinking the exterior
I’m thinking the exterior hoop of a vintage cork lined, spring-loaded embroidery hoop would work. You could ‘pad’ the exterior of the hoop with self-adhesive weather stripping to the same ‘thickness’ of the exterior spring. Place it inside and then block tight.

The outside hoop of a vintage
The outside hoop of a vintage spring-loaded embroidery hoop wrapped with black rubber, self-adhesive weather strip - carve out an area for the spring to be hidden in the foam. Place the hoop inside and then you can block and tighten as the spring mechanism will allow just a little flexibility to push against the lead type to hold them place.

3d printing is your friend here. a multi segmented ring to fit inside and a tapered plunger to push the segments out. think of something like a muffler tube expander. Send me some dimensions and I will send you a render of it.
