Sheaffer Imperial Feed Clogged


Megaten

Recommended Posts

Hello all. I have a Sheaffer 727 that has very little to no ink flow. I managed to take it apart and when cleaning the interior parts I have found very nasty black chunks stuck in many places on the feed. Im guessing the previous user used the wrong ink for this kind of pen. I have rinsed the feed in water but that hasn't done much, and converter flushing does not work because there is no ink going in or out. How should I go about cleaning it? Thanks.

 

EDIT: After reading around I am now concerned that this may be an India Ink problem...

Since you've disassembled it...

 

  • Toothbrush
  • Water-Pik
  • Ultrasonic Cleaner
  • and if those don't help, a collection of dental probes with sharp tips and different angles (common half-circle probes may not fit -- a mostly straight with just a bent tip might be needed to get into the section)

Ill try this stuff thanks. Would you say a floss would be good as well since its thin enough to go in?

 

I am saddened by the condition of this pen. No respect for it at all. Makes me more determined to fix it. Thanks for the input.

If you mean dental floss... for cleaning feed grooves -- I'm not sure. It may work for cutting through gunk but you'd still need a probe to pull out pieces, however since grooves/fins are flat sides, it may be difficult to get the floss against the surface. A tooth is rounded, so putting tension on the floss "fits" it to the curve of the tooth. Tensioning floss on a "flat" will end up shaving the corners off the fins.

If it is India Ink, you can get a cleaning product formulated to clean technical pens using heavy pigmented ink (Kohinor Rapido-Eze) at most art supply shops, including Blick's. It may take a bit but I've saved some terribly clogged fragile and rare pens with it.

 

Apparently I'm not alone, as this other thread suggests:

      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
