Nibs For The Twsbi Eco

[spaceink]

My first TWSBI is supposedly on its way and in anticipation am already thinking of playing around with nibs. The question is, which nibs will fit the ECO?

 

The other TWSBI nibs might fit? Also, what size non-TWSBI nibs will fit? How does one remove the ECO nib: screw off, pull off, or knock out?

 

And if you've switched in some other nib, feel free to post your results.

At The Writing Desk it says...

 

"This model uses the same nib as the Diamond mini and Classic ranges but nib assemblies for these models are not compatible with the Eco."

I got mine in today and the nib comes out quite easily, it didn't take a lot of force at all. I put in a #5 nib from Italix, and it was simple to put in. I think I like this design a bit more because although it is less convenient to switch the nibs, it's all one piece and the section should be more stable.

With the Eco nib pulled out, do you mind taking a measurement of the nib base width? You say a #5 nib fit, but I'm curious what the actual TWSBI nib measures.

Alright, I'm using a normal ruler and I get 5mm.

Awesome, thanks.

Hopefully sometime soon, I will order a #5 flex nib from FPR to try with the ECO.

Thanks for the tip about Italix #5 nibs in the Eco. This opens up a world of possibilities!

The #5.5 nibs from FPR are a good fit for the 580, while their #5s are ok but a touch short. I imagine they'd fit pretty well in a Mini or Eco or Classic (which all use the same smaller nib), but haven't tried it - the last time I attempted to disassemble my Mini's nib assembly, I bent a few fins...

I think that the Classic, and by extension Mini and Eco, nib is much closer to the FPR 5.5 than to the 5. The main difference between the 580's nib and these other pens' seems to be the width of the shoulders, not the length itself.

They are so inexpensive that I wil likely get a few and perhaps modify one to be even more flexy.

Yep, I think you're right. A quick comparison of the FPR #5 and #5.5 to a spare (damaged) 580 nib looked like this:

There's less of a difference in length between the nibs than I remembered - but the #5 is definitely a *little* bit shorter.

 

The 'wingspan' of the two FPR nibs was very similar (roughly 7mm), compared with 8mm for the TWSBI Diamond 580 nib; the Mini / Classic / Eco nib is closer to 6mm. You *can* fit a 580 nib inside the cap of a Mini, though - so I can't imagine the 7mm wingspan of the FPR nibs being a problem.

 

Still not game to try and swap out my Diamond Mini nib - they're jammed in pretty tight - but I'm fairly confident the #5.5 (or a #, though they're not as pretty!) will be a good fit.

I noticed the feed of TWSBI's pen is rather weak. I have bent my 580's fins, too. Didn't have this experience when changing other brand's pen's nib.

About the nib swapping, just as reminder, we use different feeders to control the ink flow of stub 1.1 vs others B,M,F,EF.

Stub 1.1 feeder got slightly heavier ink flow, so please don't mix up these two type of feeders. Cannot tell from the look outside, but you should be able to see the different in writing.

So is it possible to buy just the nibs individually (and feed) from TWSBI?

[spaceink]

Thanks for the heads-up on the feeds. Someone on the FB group for FPN just posted about putting a 5.5 FPR flex nib on their ECO. Planning to do the same, possibly getting another 1.1 stub ECO for that purpose, taking advantage of the feed's heavier flow.

You could just buy a Mini nib unit, but they cost $20. For another $9 you could have a whole pen.

Or you could experiment with #5 (or #5.5) nibs from other manufacturers that come in cheaper - I can personally recommend Fountain Pen Revolution nibs that cost $3 for EF, F, M, or $7 for B, Flex or 1.0mm stub nibs, plus $3 shipping. Others may have positive experience with other brands,too,though...

On a related note I find the ECO 1.1 down stroke much thinner than the 1.1 on my 580. I guess all 1.1 stubs are not equal.

I have found the same variation in line width between the Mini (same nib as Eco) and 580 lines. I think the nibs are just a half size smaller, even though they have the same base width (5mm/#5).
