Montegrappa Piston Problem (Le)

[Andrew_L]

Hi everybody!

Does anyone know how to disassemble Montegrappa(piston or piston emulated filler) from a limited edition series?

This is MG La Traviata Sterling Silver.
The piston does not work(don't move by knob), probably a broken stem. The knob rotate is very easy. There is no access from the pen unit hole - there is a steel thin hole. I don't know how to remove the piston knob, there are no keyhole slots like on Pelikan/Aurora/TWSBI and there are no wedges like on Omas or vintage pens.

Anyone got any good ideas?

 

Thanks!

I am afraid that with a captive converter like this one, you'd be better off sending the pen to Montegrappa to get fixed, even if it takes longer than you'd like. Good luck!

Thanks.
I do this because I'm interested, and not because there is nothing to write .

Of course, I know what you meant. It seems that with this type of built-in captive converter, there is no way to self service them, unlike a traditional piston filler where you can disassemble the whole thing, like old Omas, any MB 146/149, or most of the vintage pens etc. Captive converters/built in pistons from Montegrappa, Stipula, Visconti etc have seemed to be difficult or impossible to assemble beyond taking the nib unit out.

[Andrew_L]

Yeah, but I did it:)

Very interesting read. Thank you and congratulations.

You patience and persistence paid off, Andrew_L. Congrats! When I saw those x-ray images, I went "Oh, high tech approach!".

Yeah, but I did it:)

Thanks friends!

 

I translated post to English (by old link from above).

 

To como: There no is X-Rays, there is a CT Scans, but yeah this is hi-technology:).

I read your link using google translator:-) Even when you can see with CT Scan, it’s difficult to know if it s just superglued or heat-sensitive glued together. There you did superbly, pulling knowledge and resources together.

 

The observation of how best maintain this kind of Montegrappa pens is very helpful. I really love the design and material of the Montegrappa and Visconti pens, but their philosophy of much glue, I do not prefer.

 

Thanks again for sharing with us this daring endeavor!

Thank you so much for the translation and doing it so quickly.

Fascinating process!

[Andrew_L]

Yeah!

 

I also very liked Italien design in fountain pens, but do not understand ideology of captive converter construction. There is so much thermo-glue:( and absolutely not-friendly serviced system. I very liked piston-filler mechanism like a Pelikan or Montblanc, but in Italian pen better use cartridge\converter, like a Montegrappa Miya - one of the best modern balanced fountain pen in my opinion:).

Agreed! The captive converter makes no sense at all.

The Montegrappa Classica seems to make a good compromise where you can remove the end cap and pretend it is a piston filler or easily unscrew the barrel to reveal the converter. Still, I prefer a Pelikan or Montblance piston filler for their greater capacity.
