Increasing Ink Flow With Brass Shim: How Do You Do?


GG917

Recommended Posts

IF one is going to use shim stock for flossing or adjusting would it be best NOT to use stainless steel stock? I ask because I have full sheets of .001" and .002" stainless on hand, but no brass. I've hesitated to use the stainless because its hardness is probably close to that of the nib material and is more likely to gouge it if I don't have the shim stock properly held as I work. thanks.

This thread is more than two years old, but I thought it might be useful to add my pennorth.

 

Out of about twelve stainless-steel JoWo stock nibs, all of which required gapping, I did about half by thumb, and half by feeler-gauge shimming.

 

I was always afraid of creating IGC, an upside-down-V-shaped gap at the bottom edge, with the thumb method, and that's what happened with most. However, I found that even the effects of a severe-looking V could eventually be remedied by smoothing. I have some exceptionally smooth pens with awful IGC.

 

With steel feeler gauges you're less likely to get the IGC, but more likely to bend one tine out of parallel. The key to not doing that is to keep the gauge well away from the tip, and then twist gingerly but firmly as others have described above. In my experience, this procedure was guaranteed to seriously misalign the tines, but that is a relatively easy and quick matter to correct. It takes seconds.

 

If you do bend a tine way out of whack, you'll probably feel that you've buggered-up that nib terminally. But I've been amazed to find that using pliers, such as the tiny ones on some Swiss Army Penknives, can the bend the tine back with complete success. I have two nibs that now write brilliantly after I cack-handedly bent them out and then in again, though some serious realignment and smoothing was required. You must, of course, try very hard NOT to bend a nib tine to begin with.

 

Finally, although I'm about to buy some brass shims off eBay, I have not damaged the inner-slit surface of a nib using steel gauges, though I imagine it's possible. And in my opinion, though I continue to use both methods, shim is superior to thumb. Pace Binder and Mottishaw.

      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
