Hi, I see from the nn site that to use smaller degree rotations such as, 3.75 (96 stops), 5 (72 stops), 6 (60 stops), 18 (20 stops) it requires dual detent plungers. I assume this means engaging both of them in two separate holes. If that's the case which ones and combination? I'm just got a NN5 with RD16. Thanks if anyone might know.
