I'm Pretty Sure I Screwed This Up Myself...


Recommended Posts



I got a cool Fern Green Esterbrook J (with 1 cap) and really like the thing.


The body of the pen has a crack around the cap-threads, but it's only apparent when removing the section and bladder.


Which I did. because I wanted to see it. but that's not the issue.


The issue is the constant seepage of ink around the feed/section interface.


Again, I took the feed and nib out, but this time for a good reason! It was 0.1mm off-center and bugging me.


So now it leaks, it gets into the cap, it spreads onto the section and gets on my fingers.



How to fix it?

I am a bit of a novice at this but I would start by cleaning the section inside and out. You should be able to remove the residual ink with a wet rag and some q-tips. I'm not a big fan of soaking pens and use the manual method of cleaning.


Again being a novice at these I tend to use copious amounts of heat on the barrel when removing or inserting the section. Best to leave the Renew Point in place to avoid crushing the section which can be brittle.


In my limited experience with Green Esterbrooks, I would suggest two possible causes:


A) a crack in the section

B) a loose Renew Point--I don't know what you mean by off a mm but I'm guessing nib/lever alignment.*


You might want to wash out the cap as well.


*Contrary to popular belief, the nib and lever do not need to line up and if you think about it you will understand why.

Nah, I meant that the feed and the tines were off, the tip of the feed was just slightly to the side and it was (aesthetically) bugging the hell outa me.


Think I'll try removing the nib & feed again. On this pen they aren't one unit, but separate. See if I can reinsert them and have less leakage.


I hope the section's not cracked. I like this little pen.

If you are removing the nib and feed w/o a collar, then the collar in stuck inside the section.


Is the ink sac NEW? An old sac could have a tiny air leak which would be the cause for a drip. If in doubt, replace the sac, it could be 50+ years old.


If the feed+nib are not seated well, you could have an air leak around the nib+feed which could cause the ink leak you have.

And if the feed+nib are seated well, you would have great difficulty in pulling it out, they have to be knocked out from the back.

All Esterbrook J pens have the screw-in Renew Point assembly that includes the nib, feed, and the collar into which the nib and feed are a press fit and which is in turn threaded on the outside to screw into the section.


If you are pulling the nib and feed out of the section without the collar, then the collar is either stuck in the section or maybe missing altogether. Dried ink could have the collar stuck in place, and a combination of soaking and heat may be necessary to get it to unscrew. I've not had one so stuck that it would not unscrew with the nib and feed, so I can't advise on how you may get a grip on the collar to unscrew it - maybe by inserting the nib and feed as tightly as you can and using them to unscrew the collar.

      @Texas42 Thank you. I myself have recently had the experience of cleaning out a Wing Sung 699, in which the iron-gall ink has been sitting for six months. No damage to the metal piston rod (whereas, in a Wing Sung 3013 vacuum-filler, it would have been corroded, turned green, and contaminated the ink in mere weeks), but there was a ring of colour at the far end of the barrel that wouldn't budge, and I found it impossible to unscrew the filling mechanism to clean the interior wall of the ink rese

      Dang. You are a great friend!   One comment as a relative newcomer would be within the cleaning section: issues/differences in cleaning vacuum filler, piston filler in addition to cartridge/converter. I just cleaned out my Pilot 823 and while it wasn't particularly difficult I was a little paranoid about the drops of water that I could not get out. Perhaps this is something you are already including.   Anyway, great project and very thoughtful of you. I know it's a project fo

      Hi Smug Dill,   Nice project.  If it were me, I'd cover stuff like: - nib types available, i.e. styles, materials (SS vs gold), flex vs nails; - filling systems (I love the "thingie" comment) and how once can use them in practice (e.g. fill cartridges with a syringe); - pen body materials and their consequences (pen not balanced of too heavy and big for the hand); - and, whilst you've made it clear that you do not like vintage pens, a discussion of these beyond "I d

      Thanks for your input! Yes, not putting wood in the list of body materials warranting a mention was an oversight. I love pens with wooden bodies, but my main concern, or chagrin, is that I have not come across a wooden-bodied pen with a wooden cap that seals well. Actually, there is one, but it isn't really wood per se: the Pilot Custom Kaede's maple body is resin impregnated. All other wooden pens I have can dry out while capped and undisturbed; that includes several Platinum #3776 models.
