Waterman Nib Breather Hole Burping

Recommended Posts

Ink comes out of the breather hole while writing. I'm using Pelikan 4001 Brilliant Black which is supposed to be the driest inks around. Any advice on getting it to behave normally?


I feel as if the nib is really dry but has a waterfall for a feed.post-110164-0-09861700-1421058428_thumb.jpg

Hi perth,


Burping of ink specifically, could be caused by an erratic airflow back up the feed causing a vacuum to build up in the ink sac which, eventually, is released in one go creating a 'burp' of ink.


On the other hand if the feed has a very heavy but steady flow of ink which is not reaching the tip this may be caused by a contaminant in the nib slot or misalignment of the tines (too tight together) preventing the ink from flowing down.


Have the nib and feed been removed recently? Have you flushed the pen thoroughly to remove any possible dried ink or foreign bodies from the feed / nib / section?

I've definite flushed the pen and cleaned it quite well. The pen only burps whilst writing; as if the inkflow is so wet it spills out of the breather hole.


The nib tines are quite close together but it's not easy to fix due to the fairly responsive nature of the nib.

Hmm, well if it has a reasonably flexible nib then the tines will be moving apart as you write so that would indicate it's not an issue with them being too close together. I think if it were mine and I had tried flushing it out with some pen flush with no success (even perhaps leaving the section submersed for a couple of hours to dissolve any crud) then I would probably get the nib and feed off and take a look. It sounds as though the ink is accumulating in the feed but not transferring to the underside of the nib properly.

I saw a Duofold's feed made drier once. It seemed to have had a small rod inserted between the feed and the nib.

Well that would certainly do something to the ink flow...anything that inhibits the transfer of ink from the feed to the nib.


I'm using a Waterman Thorobred that I bought recently which arrived with a very firm fine nib so I swapped it out at the weekend for the nice soft, spare Ideal nib that I had knocking around and it is much nicer to write with, however, while the flow is very wet it skips a little and hard starts occasionally. I am pretty sure it just needs the relationship of the feed and nib adjusting so will pop it out again soon once the new ink sacs arrive.


Have you tried looking at the feed and nib under a loupe or magnifying glass to see whether the underside of the nib is touching the feed or whether it is standing off from it?

It may be that the nib is too tight against the feed in the area from the breather hole forward to the tip. I'd take a thin brass shim and run it between the nib and feed on both sides, maybe you have some gunk in there.

The nib slit is clear, just very tight. I'm willing to live with it if the the breather hole didn't flood all the time.

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav

      If one wanted to do this, one could just use the "About Me" field which appears to be unlimited in size.  And if a bunch of people wanted to cooperate, the Member Title field (or signature) could be used to this end - "Ink Giver" (or some such) could be used by those with inks to give...  No software edits required.

      I suppose the update issue could be mitigated.  One would post a link in signature, to the particular part of your profile where you list the inks that you're willing to post samples to others, gratis.  But looking at profiles, I suspect that would require an edit to the board's software, potentially a nontrivial task.

      I read your idea as getting willing givers to publicly register as members of a set of heterogenous servers, in a system in which a client would explicitly select an available server from a list, to which he/she will then send a request privately and asynchronously. Request handling in the system is unmanaged, and individual requests are handled by the targeted servers completely independently on each other. I think the model is fine, although there are some operational concerns you may want to

      First thought on the method/system of ink sharing: Think the best way, to begin with, is to follow the way of the US thread: offer up a (small) list of inks you are willing to PIF, to whoever expresses interest. Write clearly in the "mission statement" how it works, with a tiny "quid pro quo" that even a struggling student can comply with, i.e. post your opinion and a writing sample, with option of a full review if desired.   So yours truly might say: "I'm offering up samples of D
