I’ve been trying to put a Pilot Parallel nib unit into a Moonman M2. Easy, right? There are lots of pictures and guides online.

Only…they don’t work for me. From what I understand, you friction fit the Parallel nib unit into the M2 section. No go. The Parallel nib unit just falls out, there is no friction. I’ve tried pushing the nib unit really hard, to friction fit with the inner threads of the M2 section, but that doesn’t work - it just won’t go and I’m afraid I’m going to break the Parallel feed.

The Parallel nib unit won’t go into the M2 nib unit, too big. The Parallel section won’t screw into the M2 body, threads are the wrong pitch.

What’s going on? Do I have a miniature Parallel? A giant M2? Does anyone have a good video showing how this is done? I’m at my wits end, I’d really appreciate some insight. Thanks!

    To my knowledge the Parallel has never changed. I have some very old examples, probably greater than 15 years, and two brand new ones. The parts all look identical in dimensions. The M2, then, may have changed at some point but I don’t have any data on that.

    I hope part of this plan involves feeding the newly constructed Franken-pen with Pilot cartridges, because I would not trust an eyedropper pen with the wrong feed shoved into it not to leak…

    What’s wrong with the Parallel body as-is? Too long for you?

      Yes, the body is too long to fit in my pen case. Plus the M2’s demonstrator body is quite a bit nicer looking, IMHO.
