DIY – Refillable Pentel Brush
Some of you might renember that I posted my selfbuilt refillable water-ink pen here quite some time ago. It still works perfect, but I always wanted to find a way to refill a pentel brush. I made several attempts to refill it with a syringe, but they all ended in messy failure.
Picture 1: This needs a more radical approach. First cutting up to see how it looks inside...
Picture 2: Much smaller then expected! I think I could add some volumen here.
Picture 3: To save energy and time, I decide to repair a cable for my musical experiments along with the operation.
Picture 4: After cutting I replace the tiny tank wit a syringe that was leftover from some old ones I got from a chemist who cleared out his cellar after some water damage. I use shrinkable hose to seal it off. Note that I use a soldering iron instead the hot air pistol as usual, so that there's no uncontrolled meltdown of all the plastic parts.
Picture 5: Although the syringe is still removable for refilling, the system is absolutely tight. No leaking so far.
Picture 6: Meanwhile I repair the broken contact of the cable. As it is more then 30 years old, we can forgive this failure. And speaking of true quality, this Nordmende voltmeter was bought by my grandfather around 1962 and works without failure since. Believe it or not, the very first battery lasted until 2006 when it had to be replaced.
Picture 7: Of course we need a grip for the pentbrush that is firm enough, and it should be transparent to see the amount of filling. Sadly all my used up pens are to narrow to fit.
Picture 8: Good I found these remains of a broken miniature flashlight. To bad it's not transparent.
Picture 9: Problem solved.
Picture 10: All together now. The syringe is still removable, and the grip firm, sealed with hot glue.
Picture 11: I had some chromepaint left for the finish.
