I’ve been turning segmented yarn bowls for a few months and I have yet to find a good way to cut the slot in the side. I’ve tried a coping saw, a jeweler’s saw, a router with a guide and a 3/16 straight cutter (the curved surface makes it difficult), a saber saw; nothing gives a good straight-through cut. I guess some sort of computer-aided cutter would work but I’d rather keep it simple. Suggestions? Thank you in advance.

Dremel or Foredom tool with a wood cutting burr

Since I am not familiar with a yarn bowl, how deep does this cut need to be? It would seem to be that a simple jig for the tablesaw should get you an 1-1½" slot cut depending on the diameter of the bowl. I envision a simple sled with a v fence to center the bowl and a stop block to prevent slicing into the opposite side. A mag switch would make a good choice for the stop block.
My guess is he's wanting to cut a slot like this:
Make a masonite router template at the bandsaw and use auto body filler to form fit it to the bowl over plastic wrap. Use a bushing in the base of a plunge router to follow the template, probly with an upcut spiral bit. The filler dust is sticky, I'd do this outside.
