DISCLAIMER: This is one of those refill-a-hollic type things that is done for FUN more than to save money, so don’t ask “Why don’t you just buy a new pen?”
I’ve been using my inkjet printer ink to refill my rolling ball pens for a while and have had mixed success, but for the most part I’ve been successful and have been having a bit ofÂ fun. Here is my pen of choice to refill, a Pilot Precise “V series” pen (this is the Pilot Precise V7 fine tip).
My first attempt went pretty well, I used a hot paperclip to make a hole in the top of the pen barrel and injected the ink. The final step wa closing it up with some hot glue. It was almost too easy.
My next attempt was full of disaster. I did the same thing as before but as I was injecting ink into the pen it all came flowing out the tip of the pen. At first I thought the pen was broken, but I realized that I had removed the vacuum from the pen and created an open system for ink to freely flow from the top to the bottom and out the tip. Based on this I had two options:
1) Make the hole towards the tip of the pen and hold it upside down when injecting the ink. The problem with this (as seen above) is that the refill hole is exactly where I’d be holding the pen.
2) Seal the tip of the pen and proceed as before. I tried this with hot candle wax and it worked okay the first time, but subsequent times were problematic as the wax ball at the tip of the pen kept coming off.
I’ve settled with option number one as it gave me the least amount of problems with the least amount of mess. I’d still like to find a way to fill from the very top of the pen, especially through the extreme top, the flat part of the pen.
The next issue I’ve had to deal with is sealing the refill hole. As discussed in my inkjet forum here, it is tricky sealing holes in ink containers. As with my inkjet printer I tried hot glue, sticky tac, and duct tape. All worked to one degree or another, but none of them worked 100% as well as I’d like. With my inkjet printer I’ve found a great way to seal the holes, a stainless steel screw and an o-ring. Unfortunately this solution won’t work very well with my pen because the screws I have are too long for the barrel of the pen. If I could find a way to fill the pen with the tip down then I can burn a hole through the top of the pen and then seal it with the screw and o-ring.
I’m posing the question to the forum here and will see what I get!
