I’ve been wondering, for a freestanding circular staircase with open stringers, how might a person best create a nicely mitred corner where the risers meet the stringer? More specifically, how might one deal with this detail where you’d have big differences in thickness between the relatively thick laminated stringers, and the actual risers?
On a conventional straight-run stair, you might just have the outer stringers the same thickness and material as the risers, like 3/4″–simple miter. But with a winder…
Perhaps facing the outsides of the stringers and the fronts of the risers with sort of a veneer of finish wood that’s all of the same thickness to simplify making joints, but just thin enough to be bent aroud the curves of the stair?
I’ve never really seen this addressed in any book or article on stair building that I’ve thumbed through so far.

Maybe I'm not following, but what difference does it make if the rises and skirts aren't exactly the same thickness? You reference the joint to the face of the materials.
