How Do I Restore A Parker Vacumatic

This is a new old stock Parker Vacumatic Maxima in the “Golden Pearl” design. Check out the barrel clarity!

When it comes to vintage Parker pens, Parker Vacumatics are my favorite. I love their stunning art deco designs and over-complicated filling system. The pens have some quirks, too, but, I still love them.

As the Roaring Twenties came to a close, the Parker Pen Company knew it had to build on to its huge success with the Parker Duofold fountain pen or risk losing momentum in a very competitive writing instrument marketplace. Kenneth Parker, son of the company founder George Parker, figured the answer to this problem was a sac-less fountain pen that held more ink than most any other pen on the market. The key to the new pen would be a vacuum pump that used a rubber diaphragm invented in 1928 by Arthur Dahlberg. It was a device that Sheaffer, Waterman, Conklin and Wahl-Eversharp turned down. That device would be the foundation of a pen Parker first released to the public in 1932 as the Golden Arrow. Yet, the company would soon rebrand it the Vacumatic.

More than a Vacumatic-filling Parker 51, this is the rare, legendary “yellowstone” color in like-new condition.

During the next 16 years, Parker would feature the Vacumatic filling system in 3 of its most famous pens: the Vacumatic, the 2nd generation Duofold and the Parker 51. If you get into vintage pen collecting, odds are really good that you’ll encounter numerous “Vacs” that need repair. Restoring these pens is both easy and complicated. It really just depends on how lucky you get.

Parker Vacumatics and 2nd generation Duofolds with Vacumatic fillers (sometimes called DuoVacs) were made of celluloid. Celluloid is a beautiful plastic but it ages inconsistently. Some Vacs are as strong as they day they were made. Others that were exposed to prolonged heat might be brittle. In my own very non-scientific experience, I find that the “grey pearl” models of Vacumatics are often very fragile. Soaking the celluloid too long in plain water can damage a pen. ANNNND, for the love of all that you hold dear, keep celluloid pens away from open flames. When celluloid catches fire, it burns fast and hot, like a traffic flare. How do I know? One of the original fountain pen repair books said that one should heat a pen up over an open flame to make it easier to open. I did just that, when I was still learning, and holy cats! I had to leave the damned flaming pen at the bottom of a steel sink filled with water before it would finally go out. NEVER USE AN OPEN FLAME. Turns out hair dryers work just fine.

Vacumatic enthusiasts divide these pens into 3 generations. It is vital to know which generation pen you are working on. 1st Generation pens have a lockdown vacuum tail filler and often an integrated section and barrel. As such, you can’t always unscrew the section from the barrel, as you would the 2nd and 3rd generation pens. Plus, when removing the filling unit, you must first unlock the plunger so it is fully extended. Attempting to remove the filling unit with the plunger locked down will destroy the plunger and filling unit. (Authentic replacements are very hard to find.) 2nd Generation pens still have an aluminum plunger but no lockdown device. They usually have a section that unscrews, too. 3rd Generation pens have a plastic plunger and unscrewing sections. These were World War II production models, and aluminum was rationed.

On the left is the Vac Extractor Tool and to the upper right is the “stocks” style Vac unit tool. A Parker “DuoVac” awaits them below.

Unlike most pens which can be restored with the same tools, Parker Vacumatic pens need a special filling unit tool that helps you to remove and return the filling unit into the tail of the pen. I use two different types depending on the challenge of the job. My favorite looks like a medieval stocks with two different size (threaded) holes and is tightened with screws and an Allen Wrench/hex key. The small hole is for debutante and standard/major-sized filling units. The larger hole is for the oversized Maximas. I generally prefer it, as it makes resetting the new unit with a lubed diaphragm a little easier. The other design that I like was invented by Scott Pauley at The Inky Nib. He calls it the Vac Extractor Tool. Unlike the stocks tool that I normally use, this tool has the tightest threaded grip imaginable on the filling unit. My “stocks” just can’t get a tight enough grip on maybe 1 in 20 filling units. That is when I break out the V.E.T. to get the job done. Very clever design, fairly easy to use.

For today’s demonstration of Vac repair, I have chosen a 1945 Parker Duofold with a vacumatic filler. As with the 3rd generation Vacumatics and early Parker 51s, it has the plastic plunger unit. It also has a section that you can unscrew.

As usual, I start by soaking the nib and section with water just deep enough to cover the barrel threads for an hour or so to leach out the old ink and help loosen the section. An hour is usually safe enough not to damage the celluloid with the water emersion.

This is a close-up of the extracted filler unit in the stocks.

After drying off the nib and section, I test to see if I can unscrew the section with section pliers and just a few seconds of heat from a hair dryer. If I can get it started, I leave it for later. Then I thread the filling unit into the stocks and tighten up the stocks. Next I take the hair dryer and apply a few seconds of even heat around the celluloid tail of the pen. I grip as much of the barrel of the pen as I can in one hand and then slowly apply pressure turning to the left with the stocks. I am lucky with this pen that the unit unscrews fairly easily. If it fought me, I would apply a little more heat at a time until it finally gave way.

 

Watch how the wooden dowel pushes up through the section side of the barrel to remove the old diaphragm from the barrel.

After the tail-end is open, I then unscrew the section with the nib and feed all still in place. The reason that I don’t unscrew the section, even though I’ve loosened it, is that I want the added strength and stability of the celluloid at that end of the barrel while pressure is being applied to the tail end. The tail end experiences more torque and a little more fragile than the section end. I don’t want to accidentally squeeze the barrel too hard so that I crack the open end.

Sometimes the threaded black-plastic portion of the filler unit comes out, but the plunger portion remains stuck inside the tail. Sometimes the remains of the decaying rubber diaphragm remain stuck in the tail of the barrel. In these situations, I use a wooden dowel to remove them. After the big parts are out, then you need to use a dental pick or some other device to make sure all of the old diaphragm is out. You want to be especially careful with the barrel’s inner threads.

Here is the “field stripped” view of the pen. Note that I do not disassemble the section, nib, feed and breather tube. They are all perfectly happy in place 90+% of the time.

Once the pen is disassembled, the real cleaning begins. There is a trend lately among new vintage pen collectors/repairers online to prove their street cred by also knocking out the nib and feed from the section. This is entirely unnecessary the overwhelming majority of the time and risks breaking things that are perfectly fine as they are. At this point, I just dunk the still fully assembled section in the sonic cleaner along with the cap and barrel. It usually takes fewer than 5 minutes of cavitation to get them clear of old ink and debris. When you are done, dry it all off. I like to buff up the 14k gold nib…if I am not at risk of removing any two-tone plating…apply a little “Super Lube Silicone O-Ring Lubricant” to the section threads and screw it tightly on to the barrel again.

Can you see the little pellet ball in the top of the plunger from this view?

At no point did Parker actually use any glue on these pens. However, over the years, various repairmen did use glues and shellacs. That brown crud on the bottom of the plunger three photos up from here is old shellac. I scrape it off with a razor. (Please note that I leave the filling unit in the stocks for the duration of the restoration process. This helps me to make sure the proper depth is achieved when I screw the unit back into place so that the tail cap and barrel will realign properly.) Then I try to carefully remove the pellet from inside the plastic plunger’s cup. It was really difficult to get a good photo of that annoying little ball. The goal is to minimize damage to the cup of the plunger. I recently discovered there is a man in the UK who make a dremel-friendly drill system to drill out the pellets, but I have not yet tried it. Typically, I use a pin to try scooping out the pellet. It deforms the cup a little, but I try to pinch the cup back into shape when I am done.

Trim the diaphragm at roughly the point you see where I’ve lain a pin over it in the photo. New diaphragms are usually way too long to work properly. It is vital that the diaphragm can be stretched with the plunger to the point where it almost touches the breather tube inside the barrel. However, if it is so long that it impedes the function of the breather tube, the pen won’t fill or empty properly.

Inside the diaphragm is a new pellet. To start reassembling the filler, you will need to carefully get that rubber dip end of the diaphragm with the ball/pellet in it into the cup of the plunger. Once the diaphragm is secure in the cup of the plunger, you are going to hold the diaphragm in place and push the plunger up through the center of the diaphragm and invert the diaphragm from its original starting position. Once you have the original open lip of the diaphragm rolled down over the plunger, pinch it with your fingers to that metal cone part that I used a razor to scrape the shellac off of. Also make sure the same cone is held into the black-plastic threaded part of the filler unit so that the plunger is fully extended by itself without the rest of the parts joining it. This is tricky and likely doesn’t make any sense until you actually do it for yourself. While the unit is is pinched and the plunger and diaphragm stretched fully, dab some of that silicone lubricant all over the diaphragm. Finally insert the lubed up mess into the tail of the barrel. Make sure to twist the barrel back and forth so the stretched diaphragm doesn’t get stuck on the sides. Don’t release the pinched cone until it is as deep into the tail as your fingers can let it be. It should snap onto its seat when you release it. Finally, you can screw the black-plastic threads back into the barrel. If all goes well, the unit it will feel tight right where you started at. However, even when things go well, sometimes they don’t stop where you started. NEVER overtighten the filling unit. If it starts to snug up early, that’s okay. Sometimes, you might have to unscrew the stocks and reset them a little higher to finish tightening a little deeper than before. It is far more important to get the right snugging of the unit, as the unit holds the diaphragm lip in place while the plunger creates a vacuum with the rest of the rubber. If you overtighten, you can blow out the entire barrel and make it inoperable, ruining the pen. If you don’t get a tight enough closure, the diaphragm will get loose and not work. Don’t worry if the blind cap doesn’t align as perfectly with the barrel as it might have done.

At this point, it is safe to try test filling it with water. Remember it takes 10 to 12 pumps to fill it all the way. If everything looks like it is working okay, the only thing left to do is to polish it to a beautiful luster. Personally, I think wet sanding works best on Parker Vacumatics, 2nd Generation Duofolds and 51s. Tune in this November for our wet sanding tutorial.

Here is our fully restored Parker Duofold from 1945. That wet sanding really makes it stand out

How Do I Restore a Sheaffer TouchDown

Fixing a Sheaffer TouchDown filler can be easy with a little practice. Personally, I love the functionality and simplicity of the design that uses pneumatics to collapse an ink sac and allow its natural vacuum to draw ink back into the pen.

Most of what you need to fix a Sheaffer TouchDown filler is right here in this photo.

In the first photo, you will see almost all that you need to restore a Sheaffer TouchDown filler. We forgot to include a bottle of “Super Lube: O-Ring Silicon Lubricant.” In case you have trouble seeing the photo, you will need: a Sheaffer TouchDown-filling pen, a long-shaft flathead screwdriver, dental pick, scissors, razor blade, a size 15 latex rubber ink sac, an O-ring, sac shellac, rubber cement and jar of room-tempeture water. A couple of Q-tips, paper towels, corn starch and a wooden dowel might also be useful.

To get started, unscrew the cap from the fountain pen, and stick the pen nib first in water. You do not want to soak the entire pen in water, just up to the division between the section (finger-grip part) and the blue barrel of this pen. Let it soak for anywhere from an hour to overnight. This leaches out most of the old ink and softens any possible glue a past repairer might have used to secure the threaded section to the barrel.

Once the pen is finished soaking, dry it off with a tissue or paper towel. Frequently these pens can unscrew without any assistance from section pliers. Grip the section (finger grip) between your thumb and forefinger on one hand and the barrel with your other hand. Unscrew the section with a steady, gentle pressure counterclockwise (lefty loosey.)

When the section unscrews, you will see the “sac protector” and inner remains of the ink sac come out with the section. The sac protector is friction fit, and you can remove it simply by pulling straight back. Some times the old ink sac has petrified and stays on the section nipple. Sometimes it is in pieces inside the sac protector. Sometimes the old sac has melted to the inside of the sac protector. The first two scenarios are very easy to manage. The melted sac takes a long time to remove. Q-tips, wooden dowels or anything else you can use to safely scrape the inside of the sac protector clean will help. It is very important to remove all the debris from inside the sac protector to allow the new sac to slide in and operate properly.

This photo shows a complete disassembled Sheaffer TouchDown pen.

After you have finished with the sac protector, unscrew the blindcap on the tail of the pen barrel and, if possible, pull the blind cap back as far as it will go. (Don’t force it if it is frozen inside the pen.) Now take the long-shaft flathead screwdriver and ease it up the barrel until you can feel the screw at the end of the barrel and metal tube. Turn the screwdriver slowly until you feel it find the slot of the screw. Hold the blind cap tightly with one hand and gently unscrew the screw to the left. You will feel the screw come free. It seems easiest to let gravity help it fall out on to your work bench. With some gentle pressure, the plastic blind cap will pop off the metal tube. Next, you push the tube back down and out the section-end of the barrel.

Until you get used to it, the trickiest part of the restoration is replacing the latex-rubber O-ring in the blindcap-end of the barrel. You can see the black O-ring imbedded in a groove of the barrel in this photo. If you are lucky, the O-ring will still have a little pliability and it will come right out with the help of the dental pick. If you are unlucky, the O-ring will have petrified, and you’ll have to carefully dig it out little piece by little piece.

Once the old O-ring is out, you might want to use a Q-tip to clean out any dirt in that end of the barrel. The barrel on TouchDowns are often still quite clean, and cleaning it with a Q-tip might not be necessary.

You can see the old O-ring inside this Sheaffer TouchDown barrel. Use a dental pick to carefully remove the old O-ring.

Sheaffer TouchDown fountain pens used one of two different size O-rings. Most pen-part suppliers list them as either a “small O-ring” or a “large O-ring.” Large O-rings were only used in first-year Sheaffer TouchDowns (1948), which have noticeably thicker barrels than the remaining “Thin Model” TouchDowns (1949-1952), which use small O-rings. If you ever feel like dabbling in Sheaffer Snorkels, the large O-rings are also used on PFMs and Snorkel Desk Pens.

I find it is easiest to place the new O-ring into its groove with the dental pick. I fold the O-ring a little and insert it into the blind-cap opening. Then I use the dental pick to carefully get one side of the O-ring into the groove. If all goes well, I use the dental pick to drag the opposite end of the O-ring into the groove. With two-points in the groove, I go the next high point of the sack and work it into the groove. Once that is accomplished, I try to get the last high point of the O-ring into the groove. It sounds easy, but it takes some practice to do it quickly. NEVER lube the O-ring before trying to install it. A slippery O-ring will make your life miserable.

Now it is time to start reassembling the barrel apparatus. Clean off the metal tube you had to unscrew from the blind cap with a paper towel to get any old shmutz off. Then drop the screw threads-first down the tube. Use the screwdriver to help find the tube’s hole for the screw. Leave the screwdriver in the tube slotted into the screw. Put a thin layer of silicon O-ring lube around the shoulder of the tube on the screw-end of the tube. Then insert the screw and tube, screw first, into the section hole of the barrel and gently glide it with the screwdriver all the way through the blind-cap side’s hole in the barrel until the tube won’t go any farther. Rest the barrel and tube on its side with the screwdriver still slotted into the screw.

Take the plastic blind cap and fill its cup with rubber cement. (There should be a rubber washer in there, but often it is blown and the rubber cement acts as a sealant that can replace it.) You might find a way that works better for you, but I hold the blind cap with the rubber cement in my left hand and pick up the barrel assembly by the screwdriver with my right hand. It gets a little messy, but I then screw the screw into the blindcap. You know you have found the screw hole in the blind cap when you see the tube going into the blind cap’s cup and rubber cement starts smooshing out. It is important to make sure the screw is in tightly, but you have to be very careful not to overtighten the screw because it can split the blind cap in half and make it useless for the necessary air seal to make the filler work. It is important for the tube to be extended all the way to prevent the rubber cement from getting into the O-ring. Wipe the excess rubber cement off with a paper towel. Now you can work the tube back and forth to spread the silicon lube around the O-ring and get smooth operation from the barrel assembly.

Here you can see where the hardened ink sac has been scraped off to reveal the nipple underneath.

Getting back to the section assembly part of the pen, take the razor and clean the usually hardened old ink sac off the nipple of the section. Be very careful not to accidentally chip off a piece of the nipple. That will ruin your pen. Some people will insist you need to give the nib assembly a sonic cleaning at this point, but if you soaked it long enough, you likely already removed most of the old ink.

To move forward, you need to trim your ink sac to fit perfectly into the sac protector. I don’t have a definitive way to do this. I usually stick the sac (closed end first) in the sac protector, pinch it at large opening of the sac protector, pull out the sac from the protector while maintaining the pinch and then trim it with scissors. Make sure the nipple on the section is dry. Put the sac on the nipple and then put the ink sac protector over the sac to see how well it fits. If the sac is a shade too long, trim it just a bit more. If the sac is a millimeter or so short, that is perfectly fine. Remove the sac protector and then ink sac. Paint a thin layer of sac shellac on the nipple of the section and then replace the properly trimmed ink sac. Wipe off the excess shellac and let the assemble dry for a few minutes. Next rub down the ink sac with pure talcum powder (old skool and potentially cancerous, as talc is mined with naturally occurring asbestos) or corn starch. The corn starch (or death talc) helps preserve the rubber. Snap the sac protector into place over the sac.

Final assembly is easy. Screw the section back into the barrel in a clockwise (righty tighty) fashion. Some old manuals say that you should put rubber cement on the threads (you can see the remains of old rubber cement on the starting photos) to help seal the barrel, but it isn’t necessary and only gives future restorers a bigger headache. The threads seal the section and barrel nicely on their own.

At this point, you have a pen that is ready to write. I, generally, give the pen 24 hours to let the shellac set completely. Then I test it with water, flushing out any remaining old ink while making sure it fills properly.

If you want it to looks its best, you can do a wet sanding that will remove a thin layer of the plastic, removing most surface scratches and stains. It also can enhance the color a bit. Unfortunately, it also makes the remaining imprint shallower or removes it entirely, which is a reason to be judicious in deciding which pens to wet sand. Yet, how to wet sand a pen is worthy of an article on to itself.

How Do I Restore a Conklin Crescent

By on May 30, 2020

We are by no means done with the Decameron 2020 Project. However, I felt like getting back to pens for a posting. If you’ve been mostly coming for the storytelling, who knows, maybe you’ll get a kick out of a deeper dive into old fountain pens.

Here is a Conklin Crescent 2NL fountain pen in need of restoration.

Let’s look at one of the oldest “self-filling” fountain pen filling systems. In the earliest days of fillable fountain pens, any pen with a bladder or ink sac was considered self-filling. Before that you had dips and eyedroppers. Conklin invented the crescent filler in 1898. For as cumbersome as it looks, it was an insanely simple design. The pen is hollow like an eyedropper, but there is a rubber ink sac affixed to the nipple of the section. A crescent is fitted to a flat steel bar, and when the safety ring is rotated into the proper position, the crescent can be depressed, flattening the rubber ink sac within. The rubber ink sac wants to re-inflate, which fills the sac with ink and pushes the crescent back out of the barrel. Way less messy than an eyedropper, it was an instant hit. Even the famed American author Mark Twain was hired to be an advertising spokesman for the pen.

Don’t soak a Conklin hard rubber pen for very long, as it will discolor the old hard rubber. Be sure to get the water over the end of the section and on to the barrel threads.

If you already read our “How Do I Re-Sac a Vintage Pen” article, this isn’t very different. However, most of these pens are made from black hard rubber more than 100 years ago, and they are very brittle. You want to make sure you are pretty comfortable with restoring plastic/celluloid pens first. These early Conklins are getting much older and harder to find, and they break much more easily.

As with before, you will need some ink sacs, a pair of spark-plug/section pliers, a long dental pick, sac shellac or rubber cement, scissors that can cut through rubber ink sacs, a jar or cup, clean water, polish, a cloth rag, paper towels, a hairdryer, a razor blade and an ultra-sonic cleaner.

  1. Always start by soaking the nib in room temperature water over the threads of the barrel. Now the trick with old hard rubber is that water discolors it quickly. A shiny black will quickly turn to a chocolate brown haze. Don’t soak it for long, just enough to start to leech out old ink and maybe lubricate the friction fit of the section into the barrel. I certainly wouldn’t soak it for more than an hour. I’d probably soak it for much shorter a time.
  2. Next, remove the nib and section from the water and dry them off.
  3. Warm them up just a little with the hair dryer or heat gun. You only want them to be warm to the touch. Heat will also discolor the hard rubber. Plus, it can melt it.

  4. Scrape the dead ink sac out of the barrel. Be sure to be especially careful shaving the ink sac remains off the section nipple.

    Using your section pliers, gently grip and twist the section counter clockwise in an unscrewing motion. Sometimes it takes nerves of steel, patience and experience to discern the difference between the old ink sac inside the pen cracking and the barrel of the pen cracking. If the barrel cracks, you’ve likely killed the pen and made it nothing more than a parts donor.

  5. Once you get the section to start coming out, gentle, small wiggles can work it out without further stressing it from twisting. Very small wiggles. You can easily break the barrel, especially when the section looks as if it is almost out of the barrel. The more the section wiggles, the more it can act as a lever to crack the barrel. Some people choose the give the nib and section a sonic cleaning and others don’t. The sonic action can destroy the part if there is a crack already starting in it. More than 30 seconds to a minute will start discoloring the rubber. However, I’ve also found that pens this old often are filled with sediment-based inks that need something special like a sonic cleaning to remove the caked-in old ink.
  6. After the section is out, the rest is fairly easy. Scrape out all of the old ink sac from inside the barrel and very gently shave off the remaining sac on the nipple. Your razor can easily cut the nipple or cave in a wall of the nipple. Go super slow and easy with only small motions.

  7. Polishing old hard rubber is difficult. You can wear away a lot of rubber very quickly, ruining imprints and chasing.

    With everything cleaned out and disassembled, that is when I like to polish the pen and parts. You cannot go as rough on century-old hard rubber as you can plastics. I like to use MAAS metal polish on a soft terry cloth rag. Mostly I just give a light going over of the pen and cap with the polish and rag because both strip away the top layers of the rubber and can remove chasing and other imprints. It also removes some of the chocolate hazing. Using a Q-tip, I also polish the nib and crescent.

  8. Reinstall the crescent filler and lock it in place with the safety ring.

  9. Dust the ink sac in talcum power to help preserve it.

    Size and trim an ink sac that isn’t too snug inside the barrel. If you don’t have the crescent filler with the bar reinstalled first, you won’t get the proper fit.

  10. Use orange shellac to attach the sac to the section nipple.
  11. Dust the sac in pure talcum powder
  12. Very gently and slowly reinstall the sac and section into the barrel. This is another high-risk move that can crack the barrel so take it easy. You might even want to warm-up the barrel a bit.

Wait 24 hours for the shellac to dry before filling the pen. Then you are ready to write.

The finished pen should look much cleaner and be ready to write.
