I have a couple of these, one that I have not used for a couple of months is stuck solid today.

 

The filling knob will not move at all, the feed and nib have been removed, (seems much too loose a fit), tried to ease the piston but that is stuck.

 

Pity, it has the stub nib and I have some cards to write, I thought it would be perfect.

 

Have sent an email to TWSBI, do they usually help?

What ink are you using by chance?

And yes TWSBI will help. I had it happen to an ECO I was IG ink in, and they sent me a new barrel and piston head for the cost of shipping.

The ink was a blue Diamine, which ended up staining the barrel.

 

My concern is that if TWSBI send parts then this will not help, I cannot open the filling knob to allow the spanner to gain access.

I added a tad of the included TWSBI lube to the piston of my new ECO.  It is silky smooth.  However, the nib assembly is very loose, in my pen, as well.  It makes me very uneasy about the seal and have stopped using the pen.  Would Chapstik make a good seal ?

Chapstick will clog the feed of the pen.  Do not use it, or silicone, or anything else to try to "seal" where the nib and feed enter the section of the pen.

 

Contact TWSBI if you are concerned about how loose the nib and feed are, to see if they can offer a replacement.

It may be that you just need to lubricate the piston. I had something similar happen to mine in the last month or so.

Yah, that sounds like an unlubricated piston with the possible combination of being twisted too far to a tight wedge.  If the piston was already slightly dry prior and you left it inked and unused:  definitely not good.  Mine is inked and it is quite tight when in the highest position.

 

Do you have a wide rubber band or some rubber of any kind to grip the piston knob with?  If I have left pens unused for a while I have to use a wide rubber band to get the nib and feed out of a pen to clean and/or maintain.

 

If you can get that piston knob twisted it's an easy fix.

 

The feed and nib don't fit particularly tight in the Eco.  It's not like having a nib unit or using a jinhao x750-like pen where it's snug to a specific orientation.

 

That is frustrating.  Those are great pens.

Thank you all for your comments.

 

I had cleaned out the pen before putting it away but left a little water in the barrel. I am reluctant to use more force on the piston knob in case I break the threaded rod down to the piston.

 

 

 

I have taken some pics and sent them off to TWSBI for comment.

 

I have just tried to see what can be done.

 

1. Took the nib and feed out of the section, felt very loose.

2. Tried to push the piston, absolutely stuck fast.

3. Tried to use the plastic wrench to take the pen apart, would not move in either direction, just slipped around on the flats.

4. Filling knob will not move at all, in either direction.

 

I will let you know how TWSBI deal with this.

 

Thanks again

Hi,

 

If you want to use the stub nib and have another TWSBI Eco, you can just replace the nib, so that shouldn't be a problem.

 

However, your issue with the piston mechanism is worrisome.

It is either something that could be fixed by adding some lubricant as others suggested or by forcibly taking the pen apart.

 

I've had a similar issue: I used KWZ IG Green Gold in my TWSBI Eco and the ink basically destroyed the barrel. (This is a known issue with older versions of the KWZ inks, but they accidentally sent me this instead of the new version where this problem has been eliminated.)

 

Here's what I did:

I forcibly screwed off the knob using the wrench that was supplied with the pen. The piston itself was stuck in the barrel however, so I used a wire from the nib end to push out the piston and the seal. Fortunately, most of the piston mechanism survived. Unfortunately, the piston seal was damaged while I pushed it out. So I needed a new barrel (because the KWZ ink destroyed it) and a new piston seal (because I damaged it). The guys at KWZ however were extremely helpful and provided me with both (and a new version of the ink which is no longer susceptible to cause such damage), free of charge. I managed to put it together and added a little silicone grease to the new piston seal, and it works like a charm ever since.

 

I do not, however recommend using brute force to you unless you feel confident that you can take it apart without damaging it.

Thanks for the deatiled comments.

 

Current position is that the piston is stuck, the red spanner will not turn the mechanism and the filling knob will not move at all.

 

The piston has been lubricated once and then reassembled, the pen was filled and worked normally, the pen was flushed and cleaned and has been away for about a month.

 

I dont want to use force to open the pen, I think it will break.

 

I have asked TWSBI for comment. and assistance.

TWSBI were not a lot of help, they asked for lots of photographs and then just stopped. The piston was stuck by this time, loose feed and nib and the filling knob would not turn.

 

Really disappointed.

 

And then came a knight in shining armour, Pure Pens offered to sort out the pen which is fantastic, happy to commend them and show their website below
