Disassembling An Osmiroid 65/75 Screw Nib

Recommended Posts

The metal nib has suffered an impact and I have a spare nib that I'd like to replace it with. Any pointers on how to reversibly extract the nib?

1. You can unscrew the nib unit and replace by screw back the new unit.

 

 

2. If you need to separate the nib, feed and sleeve : get an old bicycle tube, cut and use the rubber to get the grip and pull out the feed'n'nib assembly from the plastic sleeve. I've done that with an Esterbrook nib. If you cannot extract from the first time, then dip the nib unit in a cup with some water for a day or two, and try again.

I used this method to disassemble Esterbrook nib assemblies.

 

- Make a cup of HOT water, just below boiling.

- Grip the nib with a hemostat or plier. To keep your fingers away from the HOT water and steam.

- Dip the collar end of the nib assembly into the hot water for about a minute.

- Hold the collar with a thin sheet of rubber, and hold the nib with another thin sheet of rubber to insulate your fingers from the hot nib.

- Try to wiggle the nib out.

- If the nib refuses to move, put it back into the hot water for another minute, and try again. Some collars need more heat to soften than others.

- Once the nib is pulled, the feed can be easily pulled out from the collar.

 

To assemble you may have to heat the collar to soften it. If the collar is brittle, it could crack when you push the feed+nib into the collar.

ac12, thanks.

 

I found that after heating and just a little wiggling of the nib, I could push down on the section towards the opposite end of the nib, and the collar would slide down and off, revealing the nib and feed.

      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
