How Much Nib Is Too Much? P 51

Recommended Posts

Technically speaking.....how much nib should be exposed on a 51? I have these two examples. Both write great. They seat differently though. One sears a little deeper.

Strange. The blue one was done by me( first timer) and the grey was done by a professional. Hahahahaha.

Reminds me of a saying, " a man with one watch knows what time it is, a man with two is never quite sure".

Sometimes they can be a bit of a pain to seat fully, but yeah, definitely the blue one is correct.

Just give me the Parker 51s and nobody needs to get hurt.

If you read the repair manual for the Parker 51 you will understand the difficulty. Specifically, the nib is dependent on the hood for its position. This means that one has to carefully measure or know from experiance and memory where to position the nib and feed based on an estimate of how the hood will move them into their final position rather than simply placing the nib last as is typical of most pens.

Interesting!

I've always just pushed the nib in as far as it will go, then screwed the hood on.

Occasionally, it would stick out too far. I always took that as an indication that I hadn't fully seated the nib, so I would remove the hood and push the nib in further until it sat where i wanted/expected it!

Thank you. I consider this my "thing i learned today" :)

If the grey one writes well, just ignore the nib peeking out. There could have been other reasons the pro decided that extra nib length was the best option.

In case you wish to write to me, pls use ONLY email by clicking here. I do not check PMs. Thank you.

Please explain.

I thought that there is a step inside the collector and that you insert the nib/feed until it contacts that step/shelf/stop.

Aligning the nib with the Hood is a matter of rotation, and you had to set the nib/feed/collector in the correct angular location before you screw the Hood on or the nib/feed will be out of alignment with the hole in the Hood.

Yeah its not a meter of rotation. Its a matter of exposed nib from the hood. It is strange because before sending to the repair person the nib kind of snapped into place when it hit the step in the collector. It a hard snap but when seated you could defiantly here a little click. After receiving the pen back you can no longer hear a positive seated sound. Anyone know what that could be?

I tried to post the pages from the 1947 Parker Repair Manual that I have stored in Dropbox, but I was unsuccessful in doing so. It goes into great detail and even has illustrations. I don't know if the source for this information is still available, but if I can locate it I will post it.

recommends actually pushing the nib in by pressing it point down into a "hard surface" which i personally find terrifying... and i've never had to do that. But it DOES say to "seat(ing) it firmly against the shoulder of the inner collector". a couple pages prior it shows a nib that is properly seated vs not. In ref to the OPs photos, the Grey is NOT.

Per the illustration of the repair manual, the old idea was to use as a heat source an open flame from an alchol lamp. Not something I would be comfortable doing.

 

And, I will add a caution, it appears that some shells and likely other parts of early Parker 51s have lost some of their thermoplastic properties. I have a Parker 51 from the early 1940s that had a shell which when heated did not go back to its origonal,shape and had to be replaced. Thus, the idea presented in the repair catalog regarding this may no longer be appropriate, irrespective of the heat source used.

Thank you for posting this link. It will save me some time finding it, or a simialer one.

The file came from the PCA. It is due for a new scan but for now https://pencollectorsofamerica.org/reference-library/parker/

 

The documents are in approximate chronological order. Go about half way down.

      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
