Replacing The Feed On A Jinhao 159

[jcreilley]

Hello,

 

I have a question that I do not think has been answered yet (at least not that my extensive googling and patrolling of this forum can find). I have a Jinhao 159 that I'm slowly turning into a flex-nibbed pen. I bought a Noodler's #6 flex nib a while ago, and while it DOES fit, albeit with some force, and it DOES write, the feed has some issues keeping up with the demands of the nib. A possibility to fix this is jerry-rigging a Noodler's ebonite feed into my 159. The only thing I've seen about this was a random post a while ago on some forum I'm not familiar with stating that he 'was going to try cutting it to fit', but I never saw a resolution to this. It seems like it would fit, just have to cut the bottom a bit where Jinhao has that flat side on their feeds. Anybody tried this? I'm not too worried about ruining the pen or other parts, since none of these things crest $10.

 

Thanks,

John

I just tried a fit of the Noodler ebonite feed to the Jinhao pen. In addition to flattening the bottom a bit, you might need to reduce the diameter by lapping the feed with a fine wet-dry paper.

 

Best of luck,

Good to know. This will probably be my pet project over the next semester at school, so I'll post updates as I progress, might be useful to somebody else down line.

It's a while, but I think it's good to share my experience with this project for others.

 

I managed to eventually sand down and shape the feed to fit the pen, it was a bit of an ugly job, but it definitely works. With a regular #6 nib, the flow is pretty wet and consistent, perhaps better than the standard plastic Jinhao feed, but it's a close call. Unfortunately when paired with a #6 Noodler's flex nib, the results are definitely better than the original feed, but it will start railroading after a few lines, so not a good solution in the long run. I'd say in the end it's a doable project, but not ultimately worth it.

It is a freaking Jinhao 159 pen. Throw it away, and buy yourself a real flex nibbed pen, like a vintage Waterman, they dont cost too much. :)

I have a feeling it's more about the journey than the destination...

And, the joy is in the going.

If you are after cheap flex may I suggest some modifications to your Jinhao. You don't need to use a different feed than the original plastic one that comes with the pen, just use a razor blade and very carefully deepen and widen the ink channels. And for the nib use a "noodler's type" nib and modify it. I got my nib from the group buy here on the forums from India but its the same that Noodlers uses in their pens.

 

You modify the nib by using a Dremel and shaping the nib to a custom shape, and then also thin the nibs metal some so it is a thinner thickness. I am going to make a thread on here of how I did it after I get done with my labs for classes but its not really hard and with some patience you end up with a superb flex pen. I have a few vintage pens including a waterman and I would put my Jinhao mod against any of my vintage pens. Granted my waterman isn't a wet noodle by any means but I would say its pretty flexy and this mod out does it which is amazing imo.

 

Here is a quick sample I wrote to demonstrate. Granted someone that actually knows how to write properly with a flex nib can do much better.

 

 

The line goes from a EF/F to about 2.5mm if you push it

Wow, that's impressive!

 

Your instructions were clear, too. Enough so that I think I might be able to do this myself. I already have some extra Noodlers pens, a Dremel, and an X-acto knife. I just need a couple of inexpensive pen bodies to try this with. (I'm not a big fan of the Noodlers pen bodies, myself.)
