I hate to see pens broken, what works for you probably wouldn't for most people. Pen repair does take a modicum of investment in the proper tools for the job.

Uhmm... I hate to see pens broken, too. That's why I don't break them. :thumbup:

Very inventive !

However in my experience t - even having the hexagon holes - this approach will will not allow to knock the feeds through of a dis assembled Montblanc nib unit!

my knock out block is sort of a rubber material, so the nib fits and the collar stops.

 

I'd be interested in seeing pictures of this.

I'll do one better.

Video.

I got it at walmart and it had hammer drill bits in it. The holes are octagon shaped, or hexagon... :hmm1:

Either way, it's perfect for nibs and knocking them out.

Dear Francis, I think Shawn has knocked out the nib from his modern 149 which has a two piece barrel, the feeder case of which has the salient lip which allows the nib and feed to be knocked out in conventional fashion.

Thanks Hari, this clarifies the confusion

Watch_art, you have a point, I was referring to vintage pre 1960 Montblanc's, while you were referring the the "modern" pens

Refraising I would say your tool can not be used for knocking the feeds from vintage MB nib units, which feature a much smaller front collar.

Sorry for the confusion I've caused.

Oh yeah, and the whole reason I pulled my 149 apart wasn't just for kicks and giggles, ink wouldn't flow. Even when I pressed it was balky. So took it apart, and found that pink bubble gum sealant MB uses was all in the feed channel. Nice. That's awesome.

So I knocked the feed and nib out and had to floss about a 1/4 inch or more of the pink stuff from the back end of the channel. Really nice. Cleaned it all out and used silicone grease to seal the threads between the nib unit and the barrel, and it's been awesome ever since!

The photos don't display for me either. I've tried it on a few Computers now. Have they been pulled from the posts?

 

I had been looking at this post a while ago and was waiting to get my nib removal tool before attempting. Now that it's here the photos which were of gererally superb quality seem to be gone.

 

Any ideas?

I have taken apart all of my 149's {I have 10} and put the nib units back together with out ANY silicone or sealant--just screwed them in!! I have been using 3-4 of them inked for the past month or so and no leaks or problems--just pure drawing satisfaction! Makes cleaning sooo easy just unscrew the nib and flush barrel and nib --like a Pelikan.

Thanks for the pictures link Lennard. Its great to hear and see fellow members doing this sort of work and it actually inspired me to do mine. Get the right tools and take your time in both researching and doing the job and you will find it very rewarding. :thumbup:

I'm in a quandary about using the TWSBI silicone oil for lubing the elastomere piston seal after reading this thread.

With the new FPN rules, now I REALLY don't know what to put in my signature.

Hi watch-art

 

There is a little bit of controversy as to whether silicone lubricants cause the purportedly self-lubricating elastomer (also silicone) piston seal to expand. This may result in increased pressure on prescious resin and cracks.

 

I'm not sure anyone has enough spare MB pens to do a controlled, lengthy trial but I believe the old adage 'if it ain't broke, don't fix it' applies.

 

I'll have to ask Eric Nikse what he does as every MB that's gone to him is always butter smooth.

      On my second trip to Japan in seven months, while the going is good

      Oh to have that translucent pink Prera! @migo984 has the Oeste series named after birds. There is a pink one, so I’m assuming Este is the same pen as Oeste.    Excellent haul. I have some Uniball One P pens. Do you like to use them? I like them enough, but don’t use them too much yet.    Do you or your wife use Travelers Notebooks? Seeing you were at Kyoto, I thought of them as there is a store there.

      It's not nearly so thick that I feel it comprises my fine-grained control, the way I feel about the Cross Peerless 125 or some of the high-end TACCIA Urushi pens with cigar-shaped bodies and 18K gold nibs. Why would you expect me or anyone else to make explicit mention of it, if it isn't a travesty or such a disappointment that an owner of the pen would want to bring it to the attention of his/her peers so that they could “learn from his/her mistake” without paying the price?

      Why nobody says that the section of Tuzu besides triangular shape is quite thick. Honestly it’s the thickest one among my many pens, other thick I own is Noodler’s Ahab. Because of that fat section I feel more control and my handwriting has improved. I can’t say it’s comfortable or uncomfortable, but needs a moment to accommodate. It’s funny because my school years are long over. Besides this pen had horrible F nib. Tines were perfectly aligned but it was so scratchy on left stroke that collecte

      My notes and advice on fountain pen cleaning

      By inkstainedruth · Posted

      @asota -- Yeah, I think I have a few rolls in my fridge that are probably 20-30 years old at this point (don't remember now if they are B&W or color film) and don't even really know where to get the film processed, once the drive through kiosks went away....  I just did a quick Google search and (in theory) there was a place the next town over from me -- but got a 404 error message when I tried to click on the link....  Ruth Morrisson aka inkstainedruth
