I’d cut a dowel in half

Or, you can use a bull nose bit:

My grandmother had one similar to that, I believe waho had it right it was composite construction dowels, or bull nose some edges and rip them off. I could be wrong but it looks like depression era stuff that’s when grandmas was made. They used anything and everthing they could find ( they were all broke) That’s also why a lot of that stuff was painted. Ive taken it apart and found cherry, oak, poplar and maple in the same piece.

What Wahoo said…

Rout a 180 degree bullnose on the edge of a board. Rip the 1/2 cylinder off. Repeat as necessary.

Glue the bullnose strips to a backer with flats oriented and sized to match the flat backs of the beads. In the case of your center photo, 7 flats to make the 90 degree turn. The flats closest to your edges match the mating surfaces, the center is 45 degrees to either edge, the two on each side between the edge and 45 are equal tilts. 0-15-30-45-60-75-90 degrees from one side… You can do the 15/75, 0/90, and 30/60 with the same setup by flipping the stock, if you think it through.

You could also glue up thin strips to form the base. Birch ply or MDF would be great for a glued up backer.

A third way to do this is to glue the bullnoses to a pair or three semi-circular “former” with flats as described above. Think “stringers and bulkheads” as in an airplane or boat structure.

Some factories had large shapers to make parts like this in one pass, which is probably how the original was made.

Can’t you just use half round molding? Since it is painted anyway, you don’t need to make your own. Home Depot should have it unless you need an odd radius.

If you do decide to make your own half round molding, a round over bit can also be used and may actually be a little easier to setup than a bullnose bit, not to mention cheaper.

I’d look at a Tambour door sheet, and price that against my time
