Parker 51 Vacumatic Writing Dry


coinlvr

Recommended Posts

Hello, I recently purchased on the eBay, a Parker 51 vacumatic from 1945 American made. I soaked it, cleaned it up and it fills properly. It writes well in the beginning a nice slightly wet fine line. However, after about 3 or 4 minutes of writing the pen starts writing extremely dry. I mean the ink barley comes out. When I squeeze the filler, the ink flows normally. I need your advice on how to fix this issue. Do I need to open the hood and see what is going on? Please advise or should I send it for restoration to an expert. It feels well and does not leak. Thanks.

Thank you. I will indeed try to take the hood off this weekend. Will Rapido eze work on the collector?

Unless you know what you are doing, I would not remove the hood.

It can be a pain to put back and align the nib.

 

Plain tap water will clean the collector just fine.

 

How long did you clean the pen?

I have had old 51s that took DAYS of soaking and cleaning (3x a day) to clean out the old ink.

The 51s collector is very hard to clean without disassembly, which I do NOT do unless I really have to.

 

If the 51 vac has never been serviced, I strongly recommend that you have the diaphram replaced. It may fail tomorrow or next week, or next month. And when it fails, you will have a mess in your pocket.

My SOP is, when in doubt, replace. Better safe than sorry.

 

Bring it to the next SF Pen Posse (in 2 weeks), and someone can take it in to replace the diaphram and clean the pen.

I have NEVER had a Vac diaphragm fail suddenly or dramatically.

I have had them fail, noticed when I tried to fill the pen, but never once filled.

 

There is no stress on the diaphragm when it is not being used to pump ink, it just sits there acting as a barrier.

 

But to each their own opinion.

Hello All, I have soaked it as recommended for 48 hours in a room temperature cool tap water. Ink has stopped coming out and the water is running clean. I filled it but again the same problem. Do you think that the problem is with potential lack of a breather tube? I will take it to the PPPC meeting this weekend in Berkeley and see where it goes. What a pity. I am in love with its patina, scratches and its wonderful yet dry nib.

      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
