Sailor Realo Disassembly & Maintenance

[...] Why do people still think pistons are made from brass and clearly not stainless steel [?]

Because Pelikan advertise their high end Souverän M800 and M1000 as piston fillers made out of brass.

im not sure if brass is suitable with ink... seriously why do people still think pistons are made from brass and clearly not stainless steel.... especially in the VAC 700 and custom 823

 

Rods in both may be SS but threads/ mechanisms are brass because it is much more expensive to machine SS.

Ink does not contact the metallic parts of the piston mechanism, on well designed pens like Pelikan, Montblanc, Pilot etc. On the 823, the filling is plunger type and the metallic shaft is in continuous contact with ink and has to be of a non reactive material like SS316/317.

How important is it to be able to re-grease or re-lubricate the piston? I'd rather not mess with it if I don't have to. I haven't gotten my 823 yet but will within a few months (2 Falcons and an CH912 interrupted my plans to get an 823). I don't mind a little ink left behind in the pen and wouldn't feel the need to disassemble the pen just to get the last bits out, but, I am concerned that the pen would need some piston maintenence let's say some 5 years down the road. Couldn't I just send it back to Pilot and let the competent pen meisters there do it?

well this is a more sound logic... seriously... its like saying a full metal piston filler pen (no bindes but bare naked metal touching the ink most of the time)... (I havent seen one but if I see one that doesnt corrode call me fancy) Edited by Algester

Only very rarely do I have to pull out the nib/feed if the feed is really clogged or the piston needs lubrication. But it really isn't that difficult with modern Japanese pens.

These are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; he that stands it now, deserves the love and thanks of man and woman. Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives everything its value.--Thomas Paine, "The American Crisis", 1776

I also think that part of the reason that the threads are made of brass is that two brass parts can slide against each other.

 

"Metals such as brass are often chosen for bearings, bushings, and other sliding applications because of their resistance to galling, as well as other forms of mechanical abrasion."

I'm still trying to figure out how to list all my pens down here.

My questions is how to disassemble the Realo, not if you, personally, prefer to pay someone to do it for you. -_-

      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
