How Do I Achieve More Ink Capacity Over Cartridge/converter Filling ?

Recommended Posts

Hello,

 

For a pen that uses international cartridges/converters, would anyone know how to effect a larger ink capacity than the standard international cartridge converter which holds 0.7 ml.

 

For example, syringe filling a full length cartridge will achieve 1.4 ml approx or eye dropper filling the pen even more; but these use syringes and eye droppers which are inconvenient.

 

Are there alternatives like squeeze fillers ? I'd imagine a sac that runs the full length of the pen would equal a full length cartridge.

 

Thanks,

Fabian

EDIT: my apologies, I did not fully read your post and realized I gave you answers you already knew. Depending on the pen, I'm not sure if there are alternative sac fillers out there you can use, but since they'd have to fit a specifc pen body, they'd likely have to be custom made.

 

Personally I don't find using a syringe all that inconvenient, especially with an eyedropper. You end up filling the pen so infrequently it more than offsets the mild inconvenience compared to popping in a cartridge, but that's just me.

Depending on the pen, you can make your own bulb filler. I did it for one pen where I could not find a converter that would fit.

  • Get a cartridge, put it into the pen to see how far into the section it goes.
  • Mark the cartridge at the section and about 1/4 inch out from the section.
  • Cut the cartridge at the 1/4 inch line
  • Fit an ink sac into the pen.
    • This is the difficult part, to figure out how long you can make the ink sac.
    • One way is to put the sac or a rod into the body to see how far down it can go.
    • Then put the section next to the body, but at the same relative position that it would screw in.
    • Then note where the cartridge is sticking out from the section.
  • Cut the sac to length then shellac it to the cartridge.

Some pens to not have enough clearance around the cartridge to do this.

      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
