Very nice! How did you make the sleeve?

 

Since you're asking for suggestions, I wonder how hard it would be to make a demonstrator version of a Sheaffer snorkel? I'm guessing the answer is "very"...

In this case the sleeve was made by drilling hole by hole and filing them together, you can imagine... a fragile job as thickness is only one (1) millimeter. For future projects I will look for a milling tool.

 

A snorkel is possibble, but they already exist, however transforming the barrel only is likely "very" possible. On the other hand, as the title of the topic says, I prefere to make never made demonsrators, but who knows someday...

 

Most difficult making are safety pen barrels... thats Fountainbel level, my target ! :D

That sounds really tricky! How many sleeves did you break before you got it right?

 

I haven't seen a demonstrator snorkel before, now I'm going to have to go hunting on google...

Sometimes indeed, you have an accident (cracks..) or need to redo and fine-tune measurements and drawings after fitting...

Generally you need a "prototype" to learn from and adjust dimensions and process steps

 

In case of the Conklin it is the FTR prototype, so reasonable acceptable

Here the cap was finished after the barrel and first run cap thread was to small, barrel did not fit in te cap

So the 4-entry cap thread was runned again while the lath was still in thread feed mode...

You can see that a very little in the cap thread, a slight desynchronisation, but all threads fit easely !

 

And the sleeve also was FTR (first time right), with angel patience...

 

Thanks for your interest !

 

Found the demo-snorkels ?

Another great achievement Rob! Maybe now it is time to design your own demonstrator. A pen combining all your favorite parts, techniques and design features. The filling system, the cap mounting and posting, etc.

Or one more challenge on the remake of existing model: the Pilot Capless (Vanishing Point). I think it would be great to see this beautiful mechanism exposed…

Good luck man. I’m a fan!

... and I think I have some redundent Pilot Capless parts for you to use. Somewhere in the big pile... So should you take up the challence: just let me know.

Hi Ben, thanks for your encouraging support !

 

At least I am interested to your Pilot proposal, please check what you have and PM me...

My "ideal pen" I have in mind... a barrel with multiple exchangable section to install different kind/brands of nibs and a common fitting cap, a demonstrator ofcourse and most likely a vacfiller..

 

To many ideas, to be realised, making a list...

I was browsing ebay and I just stumbled on an Omas 361 that's currently sitting at a fair bit less than they usually go for, with no bids and about a day left. I find it a little less aesthetically pleasing than usual as the body and cap are a bordeaux colour while the nib end cone is black, but I'm still tempted to put in a minimum bid (i.e. maybe a dollar over the starting bid), even though I already have a nicer all-black version of the exact same model.

 

I was thinking, that might be an interesting pen to turn into a demonstrator? It's a simple piston system but it's a bit unusual in that the body and section are a single piece. Also the nib end cone could be a slightly interesting piece to machine out of clear acrylic. And that way you solve the problem of the mismatched colours.

      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
