Twsbi Diamond 580 'o's ?



Eclectica

Recommended Posts

Hi there,

 

Apologies in advance for such a silly question! :blush:

 

I have had a TWSBI diamond 580 for a while and was giving it a good clean the other day - you know, nib/section unscrewed and shaking the water out of the piston etc. - when I had a horrible thought that there might have been an 'O' ring in there somewhere. I looked on the floor but found nothing - if it was there, it could have gone down the plughole in sink, bath or worse!

 

Now looking at the updated diagram of the 580 as supplied clearly shows 3 'o'-rings.

Mine now does not have an 'o' ring immediately behind the feed where it connects to the piston reservoir.

This is most likely 'o'-ring 3 in the diagram, albeit when in working position, it is to the left of 'o'-ring 7 on the inside.

 

(It has the other 2 'o'-rings though; on the body and under the metal nib ring).

My question is -

 

Is the 'o'-ring at the union of the end of the black feed to the clear plastic piston body actually necessary or actually ever present? (If I need one where can I get one?)

 

Clearly, I do not want to be in the situation where everything starts leaking all over the place in an important meeting etc! :yikes:

 

Happy New Year all.

Yes it is present on the 580 Nib.

 

It depends, but in some of the pens I work with, it is needed, others it is not. I do recommend it as it will stop ink dripping in from that part. (Happens alot to Diamond Minis which I used as test pens for customers if the O Ring is missing it will leak). And the black part which TWSBI calls a Feeder holder is most often the part which fails for my customers. So we have replacements on hand just in case.

If you are going off the diagram, and looking at No. 3, it is not in that position when assembled.

 

Here is where each 'o-ring' goes when fully assembled:

Here is the 'No. 3' 'o-ring' on the nib collar when assembled.

Great pictures and explanations!

Fountain pens are my preferred COLOR DELIVERY SYSTEM (in part because crayons melt in Las Vegas).

Thanks for the replies.

 

So if I have this right, there is no 'o' ring seal between parts 2 and 8, it just looks that way on the diagram. :headsmack:

 

This is good news that I did not flush anything away accidentally! :)

 

Cheers,

E.

You're right. The diagram shows an ''exploded'' view, making the 'o-ring' appear to be ''between'' No. 2 and No. 8, when it is actually around the nib collar (No. 2) and sandwiched by No. 4, the little, chrome piece.

 

Did you count how many 'o-rings' you have on your pen? Do you have the 3 shown? If you do, then all is good.

 

Tom.

      Not sure if this has been suggested already but would a setting for localized regions or chapters in FPN be helpful? I don't know if there is a way to find local FPN members who would be nearby. I don't know if we want to be discoverable but a setting to know how many members are in 25, 50, or a 100 miles of each other might be helpful. We can create a regions specific network like Craigslist where people could use that to connect with nearby members, conduct in person sales, arrange FPN meetups

      Hi again all, I forgot to tell y'all that I made the post about Sweden ink PIF. Most have probably found it long ago, but here's a link, anyway:

      I read your blog post and all the replies with much interest. I'm a FP user in Australia. Been part of this forum for years but rarely post. I did come across your ink sharing thread and considered participation. For me it's not lack of interest but lack of time to play around with FP and inks. I'd feel bad to put my hand up for the box and just have it sit until gosh knows when...   I also think that the FP community in Australia is smaller, and I wonder how many in the community are

      Even so, you'd end up with a fragmented list, and it becomes an O(N²) process for each prospective requestor to check what is available: effectively recreate the list of currently active servers (without any reliable up-to-date info upfront about the inks and number of samples on offer in the thread) from the sequential list of posts, which may be spread over two or even more pages, and then query each server independently to check what is currently on offer.   It comes down to not hav
