Maybe use dowel pins?

I can't answer your question, but you might try alt.home.repair.
They're a knowledgeable group.

That'll work, if I understand you correctly.

Don't use the fence of the plate joiner at all.

You will probably have to use the jointer upside down to do this, but that's
not a problem.

Hold/clamp a board wide enough to sit on top of the stool and extend beyond
the front edge; use that as an "upside down" reference surface (a helper can
exert enough downward force if you can't use clamps), it doesn't take much.

With your plate jointer upside down, cut your biscuit slots in the existing
stool, using the extended reference surface as the base (upside down) for
your plate jointer.

With your new bullnose piece right side up, hold it to the stool and mark
the center of the slot locations already cut.

On another level surface as a reference surface (bench top?), flip the
bullnose piece *upside down* and cut your slots on the marks, without using
the fence.

Flip the bullnose piece right side up ... it should now match for alignment
purposes. Hopefully you can put some clamping pressure for the glue-up by
opening the window and clamping across the stool.

Thank you, Swingman. Your explanation was excellent.
