The threads are cut with special taps, and are different for the two pens. The JOWO uses a 7.4mm x .5mm tap. You can get it here:REALLY nice work !!! Thanks for posting, and thanks for giving the specs.
I am just getting familiar with custom fountain pen construction. Can you tell me the thread size where the nib holder screws into the section, please. Thanks.
I really like the purple pen. Great job! :good:
