Glue Suggestion For Modifying Ink Cartridges

Recommended Posts

I have a totally transparent Kaweco Sport fountain pen and it is obvious that there is wasted room in the barrel beyond the end of the short international cartridge. I know I can modify a cartridge with a sac to make my own converter or I could use the pen as an eyedropper. The fact is that I like using cartridges and refilling them. Simply, I want to hack 2 cartridges to make a longer 'just fit' cartridge. I've already done that, but am looking for a suggestion to glue it back together. I thought MEK or acetone would work to solvent weld it, but it did nothing. Does anybody know what type of plastic the cartridges are made from and therefore the preferred adhesive to get a secure leak-free bond? Thanks

Suggestion : take a long international cartridge, cut a part off at the back and install a (collared) tight fitting plug at the back. No glueing needed.

Francis, that certainly does make more sense than my approach. I guess since I have never owned a long international before and the fact that I have a pile of short internationals laying around, the thought never crossed my mind. Thanks for the idea.

 

I am however the type of person who likes to reverse engineer and improve where I think I can. I would still be interested if anyone had an answer to the "type of plastic" question. If not for this instance, I think the knowledge may still be useful when trying to solve a problem such as where vintage cartridges are no longer available or rare/expensive (maybe like a Waterman C/F or Esterbrook cartridge pens for example). I am a tinkerer and like to piddle (or waste time as my wife calls it. :unsure:

I tried the opposite. I ended up giving up the idea. Carts are so cheap it was a waste of time to modify them.

From handling them, I'd say they're made of polyethylene, which is hard to glue (I don't believe there's a solvent cement available for it). You could try this:

Try Shoe-Goo. It is the best all-purpose adhesive I have found.

Just make a mini-converter from a cart and a latex sac. Looks sano, workee good. Shellac the sac on.
