Is there a way that I can fix the tines on a new pen that keep sliding past one another when I change position. If I rotate the nib to the right and start writing, the right tine will slide on top of the left tine and make a nasty creaky sound, suggesting that the iridium is grinding agaisnt each other.  When  I rotate the nib to the left, the left tine slides on top of the right one, again that nasty sound. If this keeps on happening, the iridum materials will wear down. I have had this problem with quite a few pens that I corrected by opening the tines up as much as possible. I can't do the same on this pen. Is there anything I can do or should I just let a professional handle this. Thanks

This is exactly how my pelikan M250 nib acted. I don`t think there`s anything you can do about it. The problem on my pelikan was that the nib was made from a very thin sheet of metal, which felt flimsy. Nasty feeling.

Hi

 

If it is new and not just new to you then take it back for an exchange.

 

I cannot picture your writing style that involves so much rotation of the nib though. especially to involve such an amount of rotation as to push one tine above the other, Unless there is virtually no tipping material.

 

What make of pen is it.

Upon examination under  a loupe, I see that there is a gap on top of the tipping. I wonder if this defect caused the nib to me unstable. If so, poor craftmanship is responsible for this bad nib and not prior tampering like proposed eariler. I will post a picture of what I drew.

Hi

 

It does look like there is a bit of babies bottom going on there. It could be that the BB along with those long thin tines is making it far to easy for the tine's to part under normal writing conditions and that's just to get it writing without looking for any flex.

 

That's a very strange design if its supposed to be there.  You sure its not some sort of odd special nib they sold you.

The "stability" of the tines should be governed by how the nib is bent and the properties of the metal. If the nib fits too loosely it opens up another possibility if the nib shifts. The only role I know of that the tipping plays is if there us no gap so that the tines are not able to move independently and some pressure is used while writing. If that is the problem, then you don't need to open the tines "as much as possible", rather just establish any normal gap. The V shape does suggest maladjustment in how the nib is bent, however. If it is a brand new pen, I would return it.
I know my id is "mhosea", but you can call me Mike. It's an old Unix thing.

The only nibs that I have had this happen o me on we're very old nibs! Is it possible that you are using very old nibs?
