I made a couple of kit-less pens in slightly different shapes using Jowo nib units. I've been testing these pens and since I only had one XF nib unit, I switched the section from one cap and barrel set to another. In doing so, I noticed that the nib unit is more prone to leaking in one pen than in the other. So I'm puzzled about what may be causing this.
For the barrels, I made the bores for the converter the same. The bore in one cap is slightly bigger than in the other because I used different cap threads, 1/2-20 in one and triple lead M13x.08 in the other. I do notice a difference in the tightness of those threads. The M13 threads are quite a bit tighter than the 1/2-20. It is the M13 pen that sees more leakage than the 1/2-20. Sooo, does anyone have any idea what may be causing this? Could the tighter threads be building up pressure somehow? Can the shapes of the insides of the pen affect leaking of the nib unit?
Thx for any input you can give,
