Pen Writes Only After I Force Ink Via Converter, Random Blobs While Writing Or Stops Entirely


WhatsNewSisyphus

Recommended Posts

I have a pen at hand, nemosine singularity with a stub nib (I think this is a production error and xfountainpens have been more than wonderful in helping me get a replacement, but I'd like to take it as a learning opportunity)

 

problems:

If I push the feed all the way down until it has no more to go, and twist the converter until ink flows into the section, the pen will write for a while, and in random intervals drop really big blobs of ink on the page, sometimes followed by a dry spell where the pen stops writing entirely.

 

If I adjust the feed to be more forward, just clearing the sides of the tines so that it is not visible from the top-side of the pen, the pen will write super smoothly after I force some ink down from the converter, but it will stop and not write again at all until I force more ink.

 

observations:

I do not see any ink filling the combs of the feed in either situation, but there a pool of ink can be seen between the feed and the nib in situation 1

The nib itself, if you look at it from the tip as if you are going to poke your eye out, the tines are tilted invards, so instead of being a h ( τ ) , it is more of a ( ϒ ) *SUPERBLY EXAGGERATED*

 

what I tried:

Brushing the feed and the nib, along with the converter with mild dishwashing detergent

Reseating everything about a million times

Different Inks

Very tight / Very loose nib clearance from feed

Tight/Barely touching tine adjustments

flossing the tines

flossing the feed channel

 

Thanks a bunch.

I would pick it being a shoddy feed, if you can, look at the ink flow channels, if they are not smoothish it is either going to rail road, or not come out at all. fixs that you can try include clearing out any debries inside the ink flow channels of the feed, if not you will probably have to get a new feed.

I actually had tried scoring the channels with a fresh knife, no go.

 

This morning, I recleaned the pen and really went at the feed, as I am getting a replacement, cutting the channels deep all the way down, and shaved off some height in between the channels so that it is (|--––--|). The pen now writes ok, the flow is not consistent, It started wet and now it is relatively dry, but it doesn't skip or blob, at least not yet.

At least you have it going :)

You tried different inks, but what inks?

If all you tried are "dry" inks, that would not help the problem.

What you need to try is a "wet" ink. One that is more runny.

 

At the end, all I can suggest is to send it back to the manufacturer dealer to get the ink flow problem fixed.

However, by tampering with the feed, they will probably void the warranty.

But you can try once you get a new feed in.

xfountainpens has been great and they are sending a replacement, as I mentioned in the OP.

 

I tried poussiere de lune, which is a dense/medium ink that is usually good at balancing waterfall pens, and diamine emerald, which tends to be wetter/dilute sort of ink.

I do not know how Diamine inks compare to Waterman ink regarding wetness, maybe someone else can comment.

 

I use Waterman ink in dry pens, and yours sure sounds dry.

I suggest getting a bottle of Waterman ink and using that as a base reference.

 

BTW don't seat things too many times. Doing that will cause wear. There is normal wear and then the abnormal wear. Example a cartridge is expected to be pulled and installed MANY times, but a feed is not expected to be pulled by the end user.

 

When your replacement feed comes in and is installed, I would first try it with a half load of Waterman ink.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
