Recommended J-Bar Size?


spaceink

Recommended Posts

Hello, I have a couple of lever fill Sheaffers coming in the mail (a 350 and a Craftsman) and am wondering what J-bar size is recommended, should I need to replace ones I find in them? I have a couple of 54mm J-bars but am wondering if I'd need something larger like a 62mm.

 

I did a search and couldn't find exact answers, and so thought I'd just ask the forum.

 

Thanks.

Note that there is no Sheaffer model designated as a "350". That number, when found stamped on the barrel of a Sheaffer, is the price of the pen (in cents). It doesn't identify the model per se.

 

Sheaffer pressure bars (they didn't have J-bars, strictly speaking) are pretty hardy and don't generally need replacement, but on occasion they do deteriorate. I suggest being patient and finding a correct replacement pressure bar rather than using a J-bar, which will not function as well in the pen.

 

When the pens come, if you find the pressure bars have failed, you can post pictures and other information here to determine what sort of replacement you'll need.

Thanks from a Sheaffer newbie. Good to hear that the Sheaffer J-bars are hardy. Had a recent experience restoring a recently arrived Esterbrook, where the J-Bar basically disintegrated on my removal of the sac, and so perhaps am just overly paranoid.

 

But it also makes me nervous that regularly available J-bars may not work very well as replacements. Am crossing fingers.

Sheaffers didn't have J-bars, strictly speaking. J-bar refers to a particular, simple design for a sprung pressure bar; it usually indicates a single piece of springy metal bent to form a generally J-shaped element. There are some 2-piece replacement pressure bars that are sold as J-bars, though I prefer to maintain the more specific definition so the term has more, well, specificity.

      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
