Finding cartridges for a Waterman C/F

Q:I have a beautiful Waterman C/F (Cartridge Filler), circa 1965-75. However, I can't seem to locate a converter for it. Also, it appears the cartridges are no longer being made. I dread the day when my lone cartridge that I keep refilling finally cracks. So, has anyone done some research on this and located a non-Waterman converter that is compatible with this pen?

℞x:The Waterman C/F line included some lovely pens, and I think it’s too bad Waterman no longer makes cartridges for these pens. (Are you listening, Sanford?) As of this writing, the only source of C/F cartridges of which I’m aware is the Waterman service center (1-800-BEST-PEN).

If you would rather use a converter, the converter Waterman made for its elegant Lady series in the 190s is an exact fit for the C/F. As of this writing, Waterman still has some of these.

Getting Dried Ink Out of Caps

Q:Can you tell me the best way to get ink out of old caps? I have several old pens I purchased that need cleaning. I’ve soaked them in room temperature water but I can't seem to get it all out.

℞x:First, please forgive the inky fingers in the illustrations here.

Cleaning a pen cap Depending on the pen model, there are several different methods you can try. Here are a few, from the least aggressive to the most.

The first method to try is soaking. Use water or a commercial pen flush. If you can’t find flush, you can use a solution of 1 part clear household ammonia to 10 parts water. Don’t go for more aggressive solvents, because they can — and will — damage your pen. After you’ve let the parts soak a few minutes, add a little elbow grease and a cotton swab as shown in the first illustration, and you can extract an amazing amount of ink from even an apparently clean cap. The most important place to ply your swab is at the lip of the inner cap; this is where ink really builds up. Another place to work at is the threads.

Cleaning a pen cap Next in the order of things to use is a paper towel. Twist a corner of the towel to form a spear, called a twizzle. “Screw” it into the cap, turning in the direction that will keep the towel twisted, and force it all the way down into the farthest recesses of the inner cap. If your twizzle is too fat, you may need to reshape it. Turn the twizzle a few times when it’s all the way in, to ensure that it picks up anything loose that’s hiding way down in there. Moistening the towel will often help here, and repeated applications of soaking, swabbing, and toweling will often produce a sparkling clean cap.

Cleaning a pen cap Some pen caps come apart easily; all you need to do is unscrew the end cap. (It might be tight, so you may need to soak it to free the threads or even apply a little heat to soften some shellac. Heat is very aggressive, so please be careful! If you aren’t experienced with heat, you’re probably better off not using it in this application.) Once you have a cap apart, you can clean both the main cap and the inner cap.Cleaning a pen cap The list of pens that you can do this to includes not only the vintage Parker Duofold (shown to the right), True Blue, and Pastels (1920s) but also the Jack-Knife Safety (1910s) and the DQ, some Challengers, and the Televisor (1930s). And — surprise! — there are quite a few modern pens whose caps come apart this way, such as Pelikans (shown to the left) and the Montblanc Meisterstück series. Especially with the transparent Pelikan demonstrators, the ability to take caps apart this way can prove valuable.

Cleaning a pen cap While you’re struggling with the main cap on those that come apart, stop and think. How can you do this more easily? If you have a test-tube brush or a similar one (perhaps you received one with your coffeemaker), you can use the brush to get tough inside the main cap as shown to the right. Use both an end-to-end motion and a screwing motion (twisting in both directions); this will help to extract bits of ink from the threads. You can also use the brush in the inner cap and in caps that won’t come apart, but it typically can’t get all the way down, so you’ll still need swabs or paper towels, or both. Be careful, though; the stiff nylon bristles of some brushes are harder than the plastic of the pen cap, and sometimes they’re also cut off at a sharp angle to make them more aggressive. Applying a brush like this to a pen cap can damage the inside surface, and that really looks lousy if you do it to a transparent demonstrator!

Ultrasonic cleaner You can also try running your pen’s cap, either assembled or in pieces, through an ultrasonic cleaner. You’re less likely to destroy the cap with one of the small hobby or jewelry cleaners than with a more powerful industrial model. 40 to 50 watts is a good power range. The big guys are much more aggressive, and they can put enough energy into the water to extend existing cracks (possibly even splitting the cap if the crack is bad enough) or blister a surface that is pitted or scratched all over through ordinary use. I use the cleaner shown here, which is out of production, but you can buy cleaners like it from several sources. When you buy an ultrasonic cleaner, the thing to look for is the operating frequency. Very cheap “ultrasonic” cleaners don’t actually operate at ultrasonic frequencies, and these machines do little more than extract money from your wallet. A real ultrasonic cleaner operates at a frequency of 40 KHz or higher. Avoid cleaners with the controls mounted in a hinged cover; the wires running through the hinge usually won’t last very long.
