Jinhao X750 Nib Housing Removal

[synerr]

Hi

 

I've got an x750 into which i slipped in Bock nib. So far so good. Writes beautifully although if I draw fast lines there is a bit of skip. No complaints when writing.

 

Now, the Bock nib came in it's own housing with its own feed and visual inspection alone I was wondering if the Bock housing unit can be fitted inside a Jinhao section. The Beaufort ink shop I got the nib from seems to suggest that the Bock housing can be used to retrofit a #6 nib in a Kaigelu and wondering if the x750 section is of the same inside geometry.

 

I do have a couple of broken Jinhaos running around (bought stupidly cheaply and nibs played with to destruction) but having a hard time wondering how to get the nib housing out. Brute force resulted in the total destruction of one, and not sure what the options are. Acetone?

 

Thanks

Now I can only speak about the nib housing of the Jinhao x450, but my impression is that they are pretty much compatible with the housing of the x750.

 

External Diameter of Jinhao x450 housing = 8.35 mm

External Diameter of 250 #6 Bock housing = 8.00 mm

 

So it seems that the Bock housing may be a little loose inside the Jinhao section. It may help if you can wrap a copper band around the Bock housing to enlarge its diameter, or use one round of black electrician's tape around the Bock housing to make it fit.

 

Depending on how much of a purist one is, both ways are feasible. Bock nibs coupled with their housings, feeds and converters make a supreme upgrade for most Chinese pens and are worth trying them out.

Thanks. I have managed to get the housing out of an X450 out with acetone. It just slipped out. Now I'm acetoning the X750 section and ... well ... it's messy. The housing hasn't come out but is dissolving ....

 

I have some Kapton tape ... may try that...

 

On your profile you say you love your 316 with Bock nib. Have you got any pictures and comments to share? I'm tempted get a 316 and upgrade the nib as well.

In 2 of my Kaigelu 316's, I have replaced the original nibs with #250 Bock steel EF and Titanium EF nibs. The procedures are described

Alas, due to photobucket photo web sharing problems, some of the pictures on these threads may not show properly. Hence, I added a few pics for you below:

 

You may find that it is well worth changing the nibs in your Kaigelu if you get one, as writing experience increases significantly and the pen becomes 100% reliable, no skips, no hard starts etc, At least this has been my experience.

 

Hope this helps. Cheers,

 

Frank

I am sold. The Kaigelu is most likely going to be my next pen. Thanks for sharing the write ups.

 

In the meantime, my X750 has been 'bodged together' with Kapton tape and all is working well :-)

[Frank66]

Good to see everything worked out fine. What size is your Bock?

 

Here are a few more photos of my Kaigelus from my original posts:

It's the #6 nib in bock housing according to the Beaufort Ink website. The converter is a Faber Castell I had around.

 

It's my first #6 and feels so springy compared ot my other nibs which are smaller and feel harder (TWBI 580 ALs and an Italix Parsosn Essential F).

 

Those 316s are just gorgeous. I think I now know where next salary is going <sigh />

Yeap, my gold-plated steel #6 Bock EF is truly elastic too. It is by far my most favorite nib! Also good to know that the Faber Castell converter may work with the Bock housing. Take good care. Bye.

Thanks Bluey.

We've not had any reports that the Bock housing will fit into a Jinhao X750, and to be honest it's not something we've ever experimented with here at Beaufort Ink. However, the Bock nib itself is an excellent fit in the existing Jinhao housings, so the simplest route if you want to fit a Bock into the pen is just to swap the new nib into the existing housing.

I hope that helps

I have a Bock F nib permanently attached to one of Jinhao x750. The nib is a two-tone, stainless steel, size #6 F nib, from Beaufort Ink, no affiliation, just a happy customer. It is a juicy nib, although the Pelikan Violet ink in the writing sample below makes it appear write rather dry. It takes only seconds to take the jinhao nib out and replace it with the Bock one.

The x750 nib and feed are friction fitted. Don't remove often, or you will wear out the fit. Just wrap with a flat rubber band. Grip firmly, and pull the nib and feed straight out. Be mindful of the orientation so it can be pushed back into the section, exactly the same way. Get a good grip, or you can cut your fingers.

 

The threaded metal piece that connects section and barrel also unscrews from the section.

What I needed to remove was the whole nib housing, not just nib and feed. I dissolved it in acetone :-)

Update - received the Kaigelu 316. Didn't manage to get the nib unit out but eventually dissolved it in acetone as well. Acetone FTW!!!

Very interested in this technique as I wish to remove the housing from a Kaigelu to replace with a Bock housing and nib. The acetone does not affect the section? Appreciate any pointers you'd like to share.

Thanks. I have managed to get the housing out of an X450 out with acetone. It just slipped out. Now I'm acetoning the X750 section and ... well ... it's messy. The housing hasn't come out but is dissolving ....

 

 

I need to remove the nib unit of a X450 for realignment. I am planning to use acetone, but will it hurt the powder coating of the section or the gold plating of the band on the section? How exactly did you apply the acetone?

 

Thanks in advance.
