So, to mate to the scroll you need the outer face of each tooth to

It sounds like an only-in-mass-production effort in any case.
For a found-item rebuild, one can cheat and make light-duty jaws
using
a row of pegs (basically, just drill for a series of press-in dowels).
Don't use hardened dowels, brass pins will be suitable and the
scroll won't accumulate dents.
