Chipped Bandless Duofold Cap

[JohnHKennesy]

I purchased this duofold pen as parts originally - I just wanted the barrel but I got some other things like a cracked nib and to my surprise a bandless duofold cap.

 

However the cap is severely chipped and has a hairline crack crack going all the way to the section threads. There's also some tape on the lower half of the cap. Is there anything I can do? Maybe sand the cap to the chipped area?

you could have some artisan repair it with Urushi laquer; https://mymodernmet.com/kintsugi-kintsukuroi/. I think it would still function, and less invasive than sanding the cap, but to each their own.

Interesting !

The idea could be to first disassemble the cap by unscrewing the black inner cap and to wash the ink stains and dirt.

Then I would sand the uneven surface at the bottom of the cap (1000 grit).

Then I would "create" a very thin half ring in metal (such as brass or silver) of the inner diameter of the cap.

I would glue this flat half ring inside the cap where the chip is. Before glueing I would check that the pen still screws. If it does not screew I would sand down a little the inner part of the cap where the ring would sit and also sand down the ring to flatten it.

After glueing it with epoxy glue and letting it dry 48hours, I would find a hard rubber rod of the same colour of the cap (available on the internet).

Then I would drill a hole in this rod of the inner diameter of the cap.

Once drilled I would cut the hard rubber to fit the chip.

Then I would glue the piece of hard rubber to the missing part of the cap (i.e the chip) and to the ring beneath.

Finally, once dried I would sand down (1000 grit) the freshly glued piece of hard rubber together with the cap to create a smooth surface.

Then I would polish the cap with sand paper of increasing gritt (up to 10000 micromesh).

 

The problem could be that the "ring" could be too thick to allow the cap to close...

 

Good luck !!
