Using Fountain pen ink in a rollerball Schmidt P8126

Did you know that it's possible to use [[fountain pen]] [[ink]] inside a [[rollerball pen]]? The trick is getting the correct type of cartridge, in this case the [[Schmidt P8126]] or [[Schmidt P8127]]. It's a really good cartridge; the ink flows smoothly and dries quickly. But when it's empty you're supposed to just throw it away... which is a shame and a waste of materials. Until you refill it that is!

My girlfriend just received a [[Lumos Duo Pro]] from [[Tom's Studio]] which has a nice system to fill the cartridges with Fountain pen ink and swap out the nibs. And when I noticed my rollerball cartridge was empty / dried out, I just had to know what kind of system was inside the cartridge, so I opened it up. To my surprise it had the (almost) exact same system as the one from the Lumos pen. I took the ink reservoir from the Schmidt and put in under the sink and immediately it washed out the ink and was as good as new.

I squeezed out the water and dried it using a paper towel. Then I took out the felt(?) tip with a pair of pliers and tried to wash that as well; this was more difficult, but as I wanted to put in a green ink, I wasn't too worried. I then put the tip back into the metal housing.

In the same way as with the Lumos, you just put the reservoir in your ink of choice and it will suck it right up. If it doesn't fill all the way up, the reservoir probably still contains some water; then just get a paper towel and hold it on top the reservoir and gently squeeze it to push out the water. The reservoir should fill up completely now.

Once filled up, just stab the tip back into the reservoir and push it back into the barrel of the cartridge. It will take about a minute or so before the ink will be at the tip, so be patient, and try using it. It will start out a bit lighter than you're used to, there will still be some water in the tip, but once it's gone, you've got yourself a rollerball with fountain pen ink!
