Experience On Modding Jinhao X750 With A Flex Nib?

[troubadour602]

 

Hi guys, advise needed. I just mod a Jinhao X750 and put a G nib in.

 

 

 

With the mod, the length of the nib is longer, and I can't cap it. It writes though.

 

Am I missing something here and there? Please advise, thanks.

I take it you have managed to push the nib as far as it will go? If that is the case, in order for you to get the cap to fit properly back on again is to grind the back of the nib down to make it shorter in order to fit the length of the original..

 

If you have a Dremel tool, then it makes the job easier. I have done this successfully. The only problem might be that if the nib you are using is plated then you undoubtedly will grind the plating off the edge. This my cause corrosion on the ground edge. If you are successful, you can always pull the nib out occasionally and clean it up.

 

I have experimented with this myself as well as several other members in the past. Like anything of this nature it is always trial and error!

Hello Troubadour,

 

Just my two cents, but you may want to try another nib. You have a pack of ten, sometimes, a fraction of a millimeter can make all the difference in the world.

Here are two YT vid - X750 with Zebra G. No problem with capping. Maybe this may help (I hope)

Agree with Anthony. I just performed this modification myself on two Jinhao X750s and both pens are able to be capped. From the photos you provided (as compared to my pens) it appears that the nib/feed unit can be inserted into the section a little further. It took me several attempts to get the nib/feed unit properly seated...and, as Anthony suggested, I ended up trying a different nib. Good luck.

Thank you for this question.

 

I have modified my Jinhao X-750 to use the G nib without grinding the end of the nib and it can capped well. But my problem is the pen does not flow correctly, when I wrote with flex just a few words the ink the pen will can not write anymore. I have to shake and wait for quit long time until it can write again.

 

Is this problem happen with you?

No feed problems so far. Make sure the bilateral slots in the nib are exactly aligned with the distal (toward the tip) horizontal slots in the feed when seating the unit into the section. Prior to seating the unit, make sure the feed is thoroughly cleaned of any manufacturing residue. I use a toothbrush for this. Lastly it's imperitive that you slow down your writing pace so the feed can keep up with the nib. Good luck.

My main problem when I did this modification was that when I removed the nib after about 1 month, it had corroded badly (through the chrome plating) on the underside of the nib where the nib touches the feed. The iink I was using at that time was simply Parker Quink Black. Obviously the pH of the ink is critical to longevity of the nib. In most other respects the G nib worked great.

Thank you very much.

You're welcome, Pichak!

 

Another thought I had...Anderson Pens is now selling the ebonite feeds that Nathan makes for his Ahabs and Konrads. I'm considering ordering a few of those to see if they can be used with the Zebra G Nib instead of the Jinhao X750 feed. The benefit being that Nathan has carved huge channels in his flex feeds. If this works and is significantly better, I will report back.

I will wait for your report on the ebonite feed, thank you again.

Hmmmm I am surprized that the Jinhao is not enough to supply even a flex nib to be honest as the standard feed makes both the normal Jinhqo medium nib and a Bock fine swap write on the wet side.
