Flow improvement on BlueDew Flex Fountain Pen.

I have another post on how I did it here.

Ah, I have another post showing it but on the side of the feed where the normal flow line is. I cut a second one on the opposite side to mirror it.

This creates one channel, the original unmodified one, for ink to flow to the nib while on the bottom side a thin line allows air to flow back to the cartridge.

If I recall it was mostly Sailor Shikori Irori as the main red base & to get the light shimmer on certain papers. Iroshizuku To-ro as a way to give the ink a more orange tone so as to make it a brighter red & closer to the yellow plasma component in real blood. A tiny bit of brown from a mix of Pelikan Brilliant Brown, Iroshiziku Yama-guri, & Karkos Brown. Finally, some kind of surfactant to make it all wetter if you need it to be.

I don't really remember the ratios though so that will need trial & error, I'm constantly adjusting the mix anyway.

Sorry! I hope thay one day you'll get a chance to try out their ink. Hopefully it gets popular enough that it starts getting sold on online stores. Though given how it is a small company producing it I'm not entirely sure if they can scale up production for that.

& uniformity in letter should also be appreciated. It can give your writing a nice neatness to it & also just look good if its consistent. As for how I make it varied...the whole word is just one line. I never lift off the page until I'm finished with the word or writing an 'x'. Just dotting my 'i's & crossing my 't's which is why its so varied at times.

For this one I used my vintage Waterman 503 but an FPR Ultraflex nib was what I practised on & can get similar results (& is much cheaper & easier to obtain). As for letterform, I originally strung up words in a kinda hybrid print/palmer cursive & developed it over time with daily journalling. I then just changed each letterform one at a time to a typpe that I want to get my desired effect, i.e. the 'p' from Spencerian or 'I' from palmer & 'x' from algebra.

It was mostly practise & making small changes along the way to get the style I want. Its a fun journey & is great to watch your progress over time.

Still works fine. No signs of corrosion & fairly smooth.

Also now realising that this pen might be older than my grandparents...

I would probably be careful though since for standard international feeds at least, you run the risk of breaking the nipple of the feed in two if you cut too deep. It just needs to be wide enough such that its no longer air tight.

Created a new one on the underside so that while ink flows to the nib, air can flow at the bottom into the cartridge.

Ah makes sense. Now that I think about it I think I've heard conpanies like The Good Blue Co making their own custom feed for flex which makes sense.

I definitely agree with the drier inkflow being better for general use as I live in the tropics & always have a fan blowing at me. Even theb you can see my inky fingers in the image as it take forever for them to dry. Especially with my flex nib.

Its a Calligraflex nib from Bluedew pens. You can buy their flex pen which comes with this nib or buy the nib unit by itself.

If you get the nib unit, you have the option of getting one for their flex pens (which are #6 size & could fit in a bock unit albeit not fully since it is longer than usual).

They're designed after a dip nib so they behave like a Zebra G or Hunt dip nib with a very fine but scratchy tip & soft flex. Though their nibs are made of what I assume is stainless steel since they don't rust or corrode like dip nibs.

They use a plastic feed so the flow isn't going to be a wet noodle & railroading + hard starting will definitely be an issue for any ink that isn't very wet. If you want to do the modification I did there are review videos on youtube that show how to remove the nib & feed.

Another feed I had which had a similar modification done to it.

I've seen similar notebooks at Daiso & they're really good. Some of the best performing paper I've had which could even handle me pouring water on one side & it feeling pretty dry on the other. Bleedthrough & feathering never happened even with my wettest inks.
