I recently acquired this beautiful vermilion Urushi and having hard time adjusting the ink flow.

Open the cap and open the valve just slightly to get the flow going and then if I shut-off then the pen writes a couple of paragraph and stop flowing ink.

If I keep it open slightly while I write and I think that's what it's supposed to be but the issue is...

 

Either way, the ink flow is too much like a puddle and stringy and like a writing it with a glass pen. Sort of like a water drips.

I've cleaned everything, took the feed out and nib and completely. I even cleaned with ammonia mix 1:1 solution for the feed just to make sure nothing clogging. Still writes puddles. There's no leak.

 

Since it's vintage, would the seal of the valve need replaced? Not sure.

If I shut-off then it'll stop flowing soon, If I open a bit then it keeps flowing, but either way it's too puddly.

 

The pen looks really clean and previous owner said hardly used.

 

What would it cause it to write that wet?

Well, the shut-off valve does exactly as it is suppose to: shut off ink. You will want to leave the knob open if you are writing as there is no secondary reservoir like say a Conid.

 

The seal does need to get replaced eventually. The seal is cork and does wear away eventually depending on your luck of the pen.

 

It sounds like the feed needs to be heat set (if there isn't any damage to the feed) but I would consult a nibmeister for that and possibly more nib and feed adjustment.

Thank you!

I don't think I can find the nib service in town and I wouldn't want to send the pen cross the border. It may take much longer in this Covid-19.

What is "Heat set"? Is this something I might be able to do?

 

I've had other pen, Danitrio Mae West with issues with dripping inks and burping when it was used as ED (no valve) then I went back to CC and the ink won't flow.

I sent it to nib service and the problem still persist, so I soaked the feed (disassembled) with Ammonia solution (1:1) and it worked after.

 

Thank you in advance!

It's almost certainly the rear seal that needs replacing. The symptoms are consistent with just a bit too much air being allowed into the back of the pen to replace the ink gushing out. I would replace the seal before trying to do anything to the nib or feed.

You can try and see whether Eurobox can do the repair? I have personally bought a few eye droppers from the owner at the store, and he repaired the pens right on the spot. It was amazing to see an expert do this so easily and seamlessly.

Thank you gerigo!

Yes, Eurobox can repair and the price is very reasonable however Canadapost won't able to ship internationally and won't guarantee lost package??? Due to COVID-19. I guess I have to wait or find some repair person in Canada.

In the interim you can try this.

Empty the pen

Unscrew the shutoff knob.

Pull it out very gently slowly.

Apply pure silicone grease to the shaft and slightly on knob threads. Apply the grease sparingly.

Push knob in gently

Screw the knob to barrel

Fill and try using the pen as usual.

 

Many a times this works

yes. There are some old posts by Kevin winedoc who sold the pens and I bought a few. Also iirc many good reviews on fpn.

 

Edit: found this thread which got me interested in these pens.

      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
