Does anybody happen to know where I can buy Tombow brand roller ball pens at a real B&M store (I want to try before I buy). Just to keep it on topic, Fisher space pen refills fit these pens. They also seem nice and look comfortable to hold.

I used a bare refill once; just don't give it to someone who likes to chew on his pen.

(Funny story; in chemistry class, we had some kid who liked to chew on his pen all the time. On day, we were takeing notes off a lecture when "SNAP!" All of us turned around and saw him with ink all over his mouth and face. "Uh, Mr. Kopecky, my pen just exploded in my mouth." I still laugh when I think about that today. Anyway, later that day, I handed him one of my Fisher refills saying "Chew on This!"

I picked up a few of the SAK/bullet pen combos at the local Fry's Electronics. They were on closeout for $6 per set. They have red purple and black.

Lurker - I have a couple Tombow roller balls and they are nice pens - work well and are quite comfortable. I have never seen one in a B&M store, however, only online. Not that my recommendation is that meaningful but I can recommend them highly enough to encourage you to go ahead and pick one up. I have discovered that the silver and the colors (red and green in my case) bodies hold up the best. I have a black one that has scratched more easily than the others.

I used a space pen exclusively during my college, law and graduate business school days and it served me quite well. I have cooled on them slightly as time has gone on as with a fine point that I like they tend to not lay down a very wet line and can skip a bit.

Thank you, HesNot. Is your screen name after the "He's Not Here" bar in Chapel Hill?

Lurker - Yes, I spent many nights during my college years drinking "blue cups" under the stars at He's Not Here in Chapel Hill - on a crisp fall evening after a football game or a warm spring night there was no place like it...

Nice call on your part!

Has anyone ever seen a gel ink refil for the bullet pens? I used to carry something called a Silver Sprite from Levenger which was nice because it was small and used a plain old refil, however, it was only carried for about 3 weeks before it ended up with a big ol dent in the side.

Fisher Space Pen + Cross Ion Mod

[ QUOTE ]
The Ion wrote smoothly and darkly with its gel ink, and was the most comfortable to use. However, its ink was prone to smearing.

[/ QUOTE ]

I've used the Cross Ion for three years and love the shape, function and lanyard. (I don't like the sharpish edges where it separates in the middle, however.)

But what I really hate is the lousy, leaky, short-lived, slug trailish gel ink cartridge!

For the longest time I've wanted to stick a Fisher cartridge in it somehow, but didn't know if Fisher made a cartridge small enough, or whether a retrofit would be possible. The other day I was in a Staples office supply and saw a Fisher "Universal" pressurized cartridge "for multi-action pens" and noticed that it was shorter by a hair than the Cross Ion cartridge. It occured to me that with a little ingenuity this cartridge could be installed in the Cross Ion.

And guess what, it could and I did. It wasn't too hard, and here's how.

Remove the Cross cartridge from the Ion. Take off the white plastic tail cap from the cartridge and set it aside. Over the kitchen sink, yank out the metal tube (containing the ball point) from the cartridge body using a pair of pliers, applying a twisting motion.

Still over the sink, blow out the ink using your lips over the open tail end of the cartridge. The bulk of the ink will blow out easily. However there's some clear goop that plugs the hole once all the ink is gone; blowing out this stuff takes some persistence (it took me a couple minutes of blowing--you might want to experiment with an air compressor or bike pump, etc.)

Once the ink and the clear goop are gone, rinse out the cartridge with hot running water. You might also want to twirl a Q-tip around inside to clean better.

Now put a 3/32" drill bit on your drill or rotary tool and bore out the hole where the old metal tube and ball used to be.

You are now ready to insert the Fisher cartridge. Remember this is the "universal" type cartridge, which has sections that snap off so the cartridge can fit a range of other pens (it's apparently designed for multi-action pens). Snap off both extra sections.

Now insert the new Fisher cartridge through the tail end of the old plastic cartridge. Push the new cartridge firmly into the plastic shell until the end of the Fisher is about 1/16" below the tail end of the tube. Now the business end of the Fisher is right where the old Cross ball-and-tube used to be.

Now take the white plastic tail cap that you set aside. Wad up a little piece of paper kitchen towel and stuff it into the recess on the inside of the tail cap. It should just fill the little cavity. (Or stick a tiny rubber washer in there, or maybe even a very small set screw.) Put the tail cap back on the cartridge, ensuring that the metal end of the Fisher cartridge will find a nice center.

Pick up the bottom half of the Ion pen that you set aside when you pulled out the cartridge. What you want to do now is expand the hole that the ball point sticks out of, by just a hair. You need to do this because the diameter of the Fisher tube is just slightly greater than the old Cross tube. (The tip of the Ion appears to be made of chrome plated brass, but anyway . . . .) Using your rotary tool and an appropriate grinding bit (I used a small conical diamond bit about 2.5mm), expand the hole. There's no precise measure here, just grind smooth and regular until the Fisher tube stops catching in the hole.

The last step is the trickiest. You will need to file down the plastic at the narrowest section of the Cross cartridge, since this section expands a little following the modification and would otherwise impinge on the spring. You need to file this section down using a small hand file until the diameter is .134" or less. (If you don't have measuring calipers just take it down until the plastic stops impinging on the spring.) This plastic doesn't file down easily because it's so slick, so you might want to use a diamond file.

Finally, put the new "Cross-Fisher" cartridge back into the Ion. You are done!

In my not-so-humble-opinion this is now the ultimate pen!

As a sub-note, I want to mention that I did the same mod using Staedtler Multi-action Pen Refills, and also Sterling brand (as found at Target), and it worked just the same.

Good luck. Any questions?

EDIT: Forgot to mention. Changing out spent cartridges following the mod is simple. Just pull out the Fisher cartridge from the Ion cartridge shell and push in a new Fisher (or other brand). In other words, you only have to do the modification once, and you are set for "infinite" refills. (I dont't actually know yet how long the modified cartridge will last--hopefully it won't split--but my first mod, with a Sterling cartridge, has lasted 6 weeks of moderate use so far.)
