I've made some homemade flex couplers using setscrews to bite the
shafts, but clamps are sooo much classier.
This crappy drawing is an end view of the clamp portion of a helical
flexible beam coupler. Question: how's that cut made, from b. to a.?
Slitting saw. If you were to look at a section thru the cut you'd see
a radius equal to that of the saw adjacent to "a" in your drawing.

Really? I just posted the opposite, that the cut's square-bottomed,
but now that you say it I'm not so sure.
Would the hinge be flexible enough with a big arc of metal left at the
bottom of that cut? I wouldn't think so, but if you're right it must
be.
