Converting a converter/cartridge fountain pen, is I have discovered, a very, very simple operation.
This project requires only four things, 1) first and most important, a fountain pen with a solid barrel, if the barrel has any crack or holes it will leak, 2) 100% silicone grease, which is available at any hardware store in the US (I know that my friend, Sam at Future; Nostalgic was unable to locate this in the UK and substituted teflon tape), 3) an eyedropper or syringe to fill the barrel with ink and 4) fountain pen ink.
I prefer to use a clear or demonstrator type pen for this and chose, in this instance, a Hero FPS-006. The clear barrel allows me to monitor the ink level after conversion.
Remove the nib section from the barrel and remove the converter, saving it for future use.
Apply a small amount of silicone grease to the threads that join the barrel to the nib section and reassemble the pen, wipe any excess grease away and begin writing.
Fill the barrel with the desired fountain pen ink in this case, I chose J. Herbin Poussiere de Lune.
I have done this with three pens - the Hero FPS-006, a Sheaffer calligraphy pen with a medium nib and a Pilot Preppy, all with great success.
