How Do I Glue The Slip Section Back Into A 144's Cap?

[Bo Bo Olson]

I had this in the repair section for two days...and 26 looked but none said a word.

Monday I'll be digging out my shellac.

 

I have a neighbors MB 144. The first problem might have been not screwing in the converter. I'm testing that now, in it works with a cartridge; in it is not leaking ink. The converter lost no 'water' sitting up in a cup in a paper towel.

Having cleaned the converter, it twists on well. I took the Pelikan turquoise out of the cartridge. Where there had been no leak. Needle filled it in the converter, after a day....no leaks.

 

I have shellac.

The slip cap, is not connected to the body, staying on the nib and section.

I can coat the plastic section with shellac. At least the matt front section. I imagine I need to let it dry some and keep the 'breather hole on the plastic section free. Perhaps a bent paper clip? And shove it to the bottom with a dental pick.

Because of the breather hole, keep the pen pointed down as it drys.

I can put a bit of shellac in the hollow cup in the plastic section.

 

Should I?

Or is there something better. I don't think super glue is a solution.

Hi Bo Bo

 

I saw this in the repair section, but wasn't sure, so didn't reply.

 

But I don't see what harm it can do?

Shellac shouldn't harm any of the parts - and if it doesn't work, you can scrape it out and start again.

I'm just wondering why the slip cap has become detached, in the first place?

 

Good luck.

And let us know how it works out.

[Bo Bo Olson]

I think it could have been a weakness of the 144, in the 145 came out rather rapidly.

 

The slip cap appears to be just fine. It has a little cup on top, that must have been glued to the top of the cap. MB uses a pine tar glue for the nibs....could be they used the same for the slip cap.

 

We will see.

I took a Q-tip swabbed some shellac around in the bottom and a bit on the side of the cap and slip on cap. Filled the little cup on the bottom of the slip cap about 2/3s with shellac, shoved it in with a dental pick and then turned it upside down to dry in the paper towel filled cup.

 

 

If it don't hold, I'll try filling the little cap to the top.

 

Worse comes to worse as long as the repair man knows it's shellacked, there should be few problems removing the shellac.

Do you think 24 hours is long enough to dry?

 

It's a nice well balanced pen. One of my back when I was a 20 pen, noobie and more OCD, I had three pens that were perfectly balanced. Each different. A brass piston attachment ...there for a bit back weighted standard sized but a bit wider girthed, MB 234 1/2 Deluxe ('52-54 only), a thin medium-long Geha 725 and a standard sized P-75.

 

I do like the balance of my medium long '50-60's 146 more than my '70-80's 146. Like the nib more too.

At least on my 75th anniversary 144, the slip cap is held in place by the screw of the star logo. Mine cracked due to age (I have never use the pen) and the boutique was able to replace it on the spot.

[Bo Bo Olson]

I couldn't get the top to unscrew.

 

The shellac didn't work....this time I filled the cup to the top and will try it again.

If that don't work. It's put some high % alcohol in the section clean it out and ship it off to MB or Max.

If we are talking about the inside of the cap, then I also think it should be held in place by the internal screw for the snowcap top. Because of the way the slip cap needs to fit firmly with the ring around the section next to the nib, it needs very good pressure to keep the pen capped.

 

This needs fixing by Montblanc. It would have been a simple level 1 service, but I don't know what it will be now there is shellac filling the inside the cap. Probably a new cap and a new section band.

[RoSpectre]

Please show a picture if possible; your problem is not clear. Are we talking a modern precious resin 144?

 

The logo/snowcap end piece screws into the inner cap with the breather hole, and it holds both the clip and the inner cap onto the outer cap (basically holds the whole cap together). It sounds like your problem is the threaded part of the inner cap has come off the inner cap otherwise you would not have the inner cap outside the cap, but with the logo end cap and clip still on.

 

Unscrewing the logo endcap should be your priority. There should be no glue or shellac anywhere in your cap and adding it isn't the right fix. I wouldn't go pouring alcohol in there either as it could deform the plastics.

[Bo Bo Olson]

Obviously don't have an unscrew tool, in by hand there is no real movement of the 'snow flake' top.

Is not my pen.

Have contacted Max...in that's always cheaper than MB.

Did various washes to get rid of shellac.

The regular 144s should unscrew without too much trouble; no tool needed. If it is a stainless steel or silver or special edition cap then it may be bolted in somehow but standard resin version shouldn't be. Of course it can get gummed up over time, but a warm soap and water bath usually loosens it.

 

Professional help is always best though!

[CS388]

Use rubber, or elastic. A pair of rubber washing-up gloves can be enough to grip it sufficiently.

 

Old mechanics trick: Try to tighten more (clockwise), before loosening (anti-clock). This can sometimes be sufficient to start a thread movement in a piece which has been together a long time.

Gentle heat and back-and-forth persuasion can also help

 

From what I've read here - and in your other thread about this, I'd go with RoSpectre's advice.

 

Good luck

If you are referring to the little white cap inside the red or black cap, perhaps the bolt that the snowcap screw goes into is loose and turning, or has come out. If so, this little bold is supposed to be firmly embedded into the inner cap so you can tighten up the snowcap. One pic would have instantly clarified this. These inner caps will wear down from the capping and uncapping over years of use and no longer hold. And now another thing can apparently go wrong with the inner cap, the nut for the cap screw can become loose. I think new inner caps are sometimes available for about $30.

Bobo, The snow caps just screw off. Turn it counterclockwise with a good grip. Once that comes off the clip and inner caps come off leaving just the resin shell of the cap.

Not really sure what you're trying to fix. Pics would help a lot.

[Bo Bo Olson]

Well, didn't read today's info.

So I gave it back and told them where to turn it in so it gets shipped back to MB. We have a MB "boutique" but I don't think they repair anything at all.

 

It needs a new section ring too.

Could well be she gets 145 parts which would work too I guess.

if the metal nut embedded into the inner cap is loose, you would have to hold it with something like a pencil end eraser to keep it from revolving with the snow cap when you try to unscrew the snow cap.

No. The 145 parts will not fit a 144.

Yes, that's exactly what I've had to do in the past. I've rebuilt the caps on several 144's. Parts are getting harder to find.

[Erik Dalton]

I wish they had a replacement section for the 144, something without the gold ring similar to the 145
