According to the "pen guy" at my local art supply store, all Fisher Space Pens use the same ink cartridge. The only differences in the line are the outer cases, or whatever the proper term for the pen's "outside" might be. The pressurized ink supply, the writing system, et al is all contained in that cartridge. I found this out today and this got me thinking it seems logical that a good little pen could be put together by inserting one of the Fisher refills into a piece of brass or aluminum tubing, one with an ID that's just large enough to accommodate it, and maybe making a cover for the tip with another slightly larger length of tubing. Maybe whittle a wooden plug for the other end. And a bit of epoxy putty packed around the thinner tip end just to support the writing ball.
Sitting here, looking at one of the Fisher cartridges, it seems like this would make for a practical little pen to carry in my wallet or tucked into a pocket notebook. I know this pen would not be comfortable in my big mitts for any serious writing, but it would be handy to have one right where I need it for that occasional emergency bit of scribbling. So, dose this sound like a good idea to anyone else or have I just been sitting home alone too long? Any other suggestions on my "design"?
