Being too cheap for a real fountain pen, but prefering the feel, I ended up with a number of these cheap disposable versions that I found at various places. Problem is that with the amount of writing I do these things last about two days. Therefore I needed to find a way to refill these things cheaply.
For this project you will need a number of items.
Flame Source
Paperclip
Empty Fountain Pen
Pliers
Fine Grain Sandpaper
Rubbing Alcohol
Vine Charcoal (charcoal without binder works best)
Aluminum Foil
Tape
Glue Gun
Optional:
Small Drill Bit
Funnel
Jar of Ink (only if you don't want to make your own)
Update:
Make sure that you seal the pen very well with the glue. This pen later exploded in my pocket.
Step 1Opening the Pen

In this step we will be opening up the back of the pen so that we can empty and clean it out. The first thing to do is to pull off this dinky little end cap. A pair of pliers here work well, but make sure that you don't squeeze too hard. While you can still block off the pen, it's easiest to use the cap that's included.

It involves using a syringe to create a vacuum in the pen so that it sucks ink into the reservoir.

thx for the description on how to make the ink. i didn't think it was possible for the fine charcoal bits to make it through the fibre feed. :)
the same technique can be used to refill any disposable pen that makes use of liquid ink. i've tried it with Pilot Hitech point and a couple of other brands that has a finned section. The ink I used is Parker Quink. I've not gotten around to making ink myself.
Also, a syringe is the absolute tool for re-inking a disposable (or really any other kind) of pen. Control, precision, and minimal mess potential. A 5-10cc syringe is just the right size for the quantities of ink you'll be dealing with.
Try to get a 14ga or bigger needle if you have a Luer or Luer-lock-equipped syringe and grind/sand the end dull so you don't accidentally give yourself a nice big inkjection.
If you can't get an actual hypodermic syringe, try to get one of the ones with the built-in pointy plastic nozzle like they give you after you get your wisdom teeth taken out.
Syringes can be ordered online (as long as you are 18 or older) from Andro USA Inc.
