A New Lease on Life for an Old S.M. Frank Bakelite


by Kenneth Lieblich

A couple of weeks ago, I restored a Redmanol pipe for a customer and, as good fortune would have it, its Bakelite cousin appeared on my workbench. However, this time the Bakelite pipe is for sale! It’s a real beauty – and quite old. It’s an S.M. Frank Bakelite bent bulldog. It has a lovely old-world feel about it, with a handsome band – and it even has its matching leather case! This pipe has an orific stem and that marks it as being around a century old. To learn more about that particular bit of pipe history, please have a look at Steve’s article on the subject here. Given my recent experience with Redmanol and given its similarity to Bakelite, I thought I’d give it a go. It’s an old timer and it will always carry a few signs of its use and age, but that is definitely part of this pipe’s charm. The marks on the pipe are simple and straightforward. On the left side of the shank, it reads Frank [over] Bakelite. Inside the pipe case, there is a logo which reads Frank [over] Trade Mark.I suspected that the name Frank was referring to the S.M. Frank company, but I went to Pipedia to check. It turns out that the S.M. Frank history is a tangled mess of brambles and twigs. It involves Kaywoodie, KB&B, Reiss, Demuth, and many others. It’s messier than a dog’s breakfast, as one of my schoolteachers liked to say. I don’t have the patience to do it justice here, but I will provide a few tidbits. Here’s a quotation from Pipedia:

In the year 1900 Sam Frank Sr. started his own business, selling pipes and other tobacco items. His original office was located at 20 W. 17th Street, NYC. He was also closely associated with the sales staff of Wm. DeMuth & Co., selling their line of pipes. It was at this time that Mr. Frank first met Ferdinand Feuerbach and formed what would be a lifelong friendship. Mr. Feuerbach started working for the DeMuth company in 1897 and by 1903 had become the production manager. In 1919, when Mr. Frank needed an experienced pipe man to run his pipe factory, located at 168 Southern Blvd., in the Bronx, he persuaded his old friend Ferdinand to join him. Mr. Feuerbach is credited with developing DeMuth’s popular Royal DeMuth and Hesson Guard Milano pipelines. In 1922, when S. M. Frank purchased the Manhattan Briar Pipe Co. the company incorporated. In 1933, the paper Medico filter was introduced along with the Medico brand line of pipes. The Medico filter is the “original” and most absorbent paper filter on the market that is recognized by pipe smokers world-wide. Filtered pipe smoking, a debatable issue among pipe smokers, reduces tars and nicotine in the smoke stream to make a “safer” smoke.

Meanwhile, over in the PipesMagazine forums, there’s a lengthy discussion on the subject from user, jguss. I won’t try to do the article justice in this blog post, but I recommend you read it here. One of the useful things that came out of it, however, is the following org chart.I cannot date this pipe beyond saying that it is about 100 years old. It’s not possible for me to be more precise than that – other than to say that the pipe cannot precede 1907, as that was the year that Bakelite was invented by Leo Hendrik Baekeland. Anecdotally, this pipe looks like similar KB&B (Kaufmann Bros. & Bondy) pipes of the era, so it may come from that genealogical line (so to speak). Let’s move on.

A closer look at the pipe shows a few problems. The stem has some scratches and wear – I will have to handle the Bakelite carefully. The stummel is pretty worn and dirty. It has a few scratches and nicks. Around the top of the bowl, there is some odd ‘stuff’ stuck to the wood. More on that later. Both of the mortises in the shank and stem had matching broken-off halves of a bone tenon. They’re stuck in there. There’s a lot of work ahead! I decided that my first job would be to extract the tenon halves. This was nerve-wracking stuff because I was not at all sure that I could get them out without cracking either the shank or stem (or both). The photos here don’t really tell the whole story. I tried extracting with pliers; I tried extracting with a screw – both unsuccessful. I fiddled for while and decided that I needed to drill the tenon out. It was clearly risky, but the pipe wasn’t useable in its current state anyway. So, I took the stem and stummel and threw them in the freezer for 30 minutes or so. I wanted to (hopefully) make the bone tenon more brittle by freezing it. I also wrapped the end of the stem very tightly with hockey tape in a quixotic hope that that might prevent the Bakelite from cracking. I then took the thinnest drill bit that fit inside the draught hole of the tenon and drilled carefully and slowly. I then increased the size of the drill bit one by one – oh so carefully – until the tenon began to crack. As more and more of it cracked, I was able to pull the debris out. This took a while, as I worked on both halves, but it was a complete success. Deo gratias! I then went searching in my boxes for a replacement bone tenon – I have hundreds! Eventually, I found just the right one. I was finally able to get on with cleaning. I used oil soap on a few cotton rounds and wiped down the stem to provide an initial cleaning before moving on to the next steps. The primary cleaning came next. I disinfected the inside of the stem with pipe cleaners and cotton swabs dipped in 99% lemon-infused isopropyl alcohol. I scrubbed thoroughly to make sure the interior was very clean.Next, I set about fixing the marks in the Bakelite. This was done by filling those marks with clear cyanoacrylate adhesive. I left this to cure and moved on.The next step was sanding. First, I reduced the bulk of the cyanoacrylate repairs. I removed the excess adhesive as near to the surface as possible, without cutting into the Bakelite. Following that, I used all nine of the micromesh sanding pads (1,500 through 12,000 grit) to sand out flaws, even out the Bakelite, and provide gentle polishing of the finished surface. I also applied pipe-stem oil while using the last five micromesh pads. There was a wonderful, clear, ruby-like glow to the stem when I was done.As the stem was (nearly) complete, I moved on to the stummel. The first step was to ream out the bowl – that is to say, remove all the cake inside the bowl. This accomplished a couple of things. First (and most obviously), it cleaned the bowl and provided a refurbished chamber for future smoking. Second, when the old cake was removed, I could inspect the interior walls of the bowl and determine if there was damage or not. I used a reamer, a pipe knife, and a piece of sandpaper taped to a wooden dowel. Collectively, these ensured that all the debris was removed.My next step was to remove the lava on the rim. For this, I took a piece of machine steel and gently scraped the lava away. The metal’s edge is sharp enough to remove what I need, but not so sharp that it damages the rim.Similar to the stem, I then cleaned the stummel with both pipe cleaners and cotton swabs dipped in lemon-infused 99% isopropyl alcohol. With a pipe this dirty, it took quite a while and much cotton to get clean.I then decided to ‘de-ghost’ the pipe – that is to say, exorcize the remaining filth from the briar. I filled the bowl and the shank with cotton balls, then saturated them with 99% isopropyl alcohol. I let the stummel sit overnight. This caused the remaining oils, tars and smells to leach out into the cotton.To tidy up the briar, I also wiped down the outside with some oil soap on cotton rounds and used a toothbrush in the crevices. This did a good job of cleaning any latent dirt on the surface of the briar. The last step of the cleaning process was to scour the inside of the stummel with some soap and tube brushes. This was the culmination of a lot of hard work in getting the pipe clean.However, what it did not do was remove the weird stuff stuck around the rim. Then I realized that this pipe must have had cap once upon a time. That cap is long lost to the mists of history. I looked in my stores and found several caps, but not that fit this pipe. No problem – this pipe doesn’t need it and would look great (I daresay better) without one. It took some mighty strong sanding with 220-, 400-, and 600-grit sandpapers to remove all the gunk. I then used all nine micromesh pads (1,500 through 12,000 grit) to sand the outside of the stummel and finish it off. This sanding minimizes flaws in the briar and provides a beautiful smoothness to the wood. I did add some stain to the briar in order to replace what had been lost in the sanding – but forgot the photos. Anyway, I rubbed some LBE Before & After Restoration Balm into the briar and let it sit for 30 minutes or so. The balm moisturizes the wood and gives a beautiful depth to the briar. I then buffed the stummel with a microfibre cloth. For the final step, I took the pipe to my bench polisher and carefully buffed it – first with a blue diamond compound, then with three coats of carnauba wax. This procedure makes the pipe look its best – the stummel sings and the stem glows.

All done! This S.M. Frank Bakelite bent bulldog looks fantastic again and is ready to be enjoyed by its next owner. I am pleased to announce that this pipe is for sale!

Restoring a Unique Bakelite Dublin with a Removable Bowl


Blog by Steve Laug

This next pipe on the table is a really unique looking piece. It is like a Bakelite version of a Falcon Metal pipe but I think it is older than them. The pipe had a yellow Bakelite single unit base and stem with a metal decorative ring and a brown Bakelite bowl. There is no mark or stamp any where on the base or on the bowl to identify the maker of the pipe. Jeff bought it from an antique store on September 09, 2017 in Salt Lake City, Utah, USA. The pipe had been well smoked. There was a light cake in the bowl and a bit of lava on the rim top. The base was dirty inside and there were light tooth marks on the top and underside of the mouthpiece. Jeff took some photos of the pipe before he started his clean up work. Jeff took some closer photos of the bowl and the sides of the stem. The rim top looks to be in good condition. The inside of the bowl has a thin cake in the bottom half of the bowl. The rim top is dirty. The stem/base is clean but has some light tooth marks on both sides. He took a picture of the base of the bowl and sides of the bowl. It is a very nice looking Bakelite bowl and base. There was some buildup and sludge on the bottom of the bowl and the base. The brass ring was loose and worn looking. It is not clear to me if the brass ring is meant to be on the base or on the bowl.Jeff unscrewed the bowl from the base and what a collection of tars and oils had collected in hollow of the base and on the surface where the bowl sat when screwed in. He also took photos of the ring. The threaded base of the bowl was filthy with tars, oils and shards of tobacco on the surface. This unique Bakelite base and bowl is an incredibly light and almost indestructible pipe. It is the kind of pipe that can be put in the pocket and carried along. The filthy pipe had cleaned up well. Jeff had reamed the bowl with a Savinelli Fitsall Pipe Knife to remove the light cake. He then scrubbed the outside of the bowl and base with undiluted Murphy’s Oil Soap and rinsed it off. He cleaned the inside of the shank and the airway in the shank and stem with alcohol, cotton swabs, and pipe cleaners. The Bakelite cleaned up remarkably well. The grain in the bowl portion was very nice. The gold base ring was thin and clean and looked very good. The base and stem is Bakelite as is the bowl. There are some faint tooth marks and chatter. It has an orific button (round air hole) on the end of the button. I took some photos of the pipe to show the condition when I received it. It was an interesting piece of pipe history from someone’s collection and it had been well smoked. I took close up photos of the bowl and rim top and the stem to show their condition. You can see the clean bowl. There were some light nicks and scratches on the Bakelite rim top that would need to be polished out but it was nice looking. The stem and base looks really good. There was some darkening on the end of the stem and the bottom of the base but it was very clean. There was some light tooth chatter on both sides.I took the pipe apart and took photos of the parts to show how it all worked. The base had tobacco stains and tars but was very clean. Have a look at the parts. I polished the yellow Bakelite base and mouthpiece with micromesh sanding pads – dry sanding it with 1500-12000 grit sanding pads. I wiped it down after each pad with a cloth impregnated with Obsidian Oil. I worked some Before & After Restoration Balm into the surface of the base and stem. I find that it works well to clean, preserve and protect Bakelite as much as it does briar. I like the way it works and the way the base looks when it is polished. I spread some white all purpose glue on the ledge on the base to anchor the brass band on the top. I used a dental spatula to spread the glue around the surface of the Bakelite. I pressed the band in place on the base and screwed the bowl on top to press it down into the glue until the band cured.I polished out the scratches and nicks on the rim top with micromesh sanding pads. I worked my way through 1500-12000 grit pads and wiped the top and bowl down with Obsidian Oil on a cloth to protect the surface after each pad. I worked some Before & After Restoration Balm into the surface of the Bakelite bowl. I find that it works well to clean, preserve and protect Bakelite as much as it does briar. I like the way it works and the way the base looks when it is polished.I really enjoyed refurbishing this unique Bakelite Base and removable Bowl because I love the final touches that make it sing. I put the bowl and stem back together to have a look at the whole with all it of it polished. I carefully buffed the bowl and stem with Blue Diamond on the wheel. I gave it several coats of carnauba wax and buffed the pipe with a clean buffing pad to raise the shine. I hand buffed it with a microfiber cloth to deepen the shine. It is fun to see what the polished bowl looks like with the silver plated band and the polished yellow Bakelite base and stem. This unique Bakelite Dublin System is light weight and it is clean and ready load up with a favourite tobacco. Have a look at it in the photos below. As noted above, Its measurements are Length: 4 ½ inches, Height: 1 ¾ inches, Outside diameter of the bowl: 1 ¼ inch, Diameter of the chamber: 1 inch. The weight of the pipe is 26 grams/.92 oz. I will be putting it on the rebornpipes store in the American (USA) Pipemakers section. If you would like to add it to your collection let me know by message or email. Thanks to each of you who are reading this blog. Remember we are not pipe owners; we are pipemen and women who hold our pipes in trust until they pass on into the trust of the next generation.

When life was like a summer day,
And I was under twenty,
Three loves were scattered in my way –
And three at once are plenty.
Three hearts, if offered him with grace,
One thinks not of refusing.
The task in this special case
Was only that of choosing.
I knew not which to make my pet –
My pipe, cigar or cigarette!

— Henry S. Leigh (1837-1883), British writer, playwright and lesser poet, “My Three Loves,” 1875

INTRODUCTION

As a writer, I make it a habit to look words up in the dictionary before committing to print, even when I am confident they are the best to convey my true messages.  In the process, I have often been surprised to learn how many words come nowhere close to their common usage.  I have stopped using fantastic (related to a fantasy or other such literary, delusional or wishful thinking, when I want to suggest excellent; I’ve dropped mesmerizing (named for the Australian physician/showman F.A. Mesmer, which deals with the alleged ability to place someone in a trance so deep the subject cannot feel pain, as opposed to something considered fascinating, and of course I have my pet peeve: unique, or existing as one, sole, solitary, alone.  Therefore, there can be no higher degree than unique, such as more, very or, God help us, totally unique, dude.  Thomas Jefferson’s unique literary and diplomatic exception to the same rule applied to another word, in penning the “Declaration of Independence” and referring to a more perfect Union, was a brilliant misuse of the language directed to good old King George V, whom the masterful wordsmith, diplomat and statesman knew would not miss the Colonial revolutionary’s attempt to play nice.

Somewhat of a language purist, therefore, I was disappointed upon checking the past participial adjective scintillating in the OED.  I hoped to find a meaning with common uses I have heard indicating something more alluring in a sensuous sense.  I suffer from chronic migraines and was struck by the sole usage referenced, to scintillating scotoma, the technical name for auras we who live with the often blinding, nauseating, debilitating torture of these attacks call the event that precedes the onset of the pure anguish that can last 12 hours, 24 or for days before running out of air, if you will, burning out (or more descriptive of their quality, terminating with a thermonuclear-like reaction) – and then returning, as they come in cycles of three or so for me.  Thanks to my dear Dad, however, who taught me the value of a good double meaning in any title, I moved to the verb scintillate and found more general references to sparks, flecks, twinkles and flashes of light, without the negative but illustrative connection of scintillating scotoma.

The story behind Bakelite and two of its competitors, and the Machiavellian way the three in time merged into a single Bakelite incarnation, is one for the annals of business law.  The basic original resin used to make Bakelite, a phenol formaldehyde based synthesis, was patented as such in 1900 by Leo H. Baekeland, a Belgian-American chemist.  Baekeland’s synthetic plastic, the first formulated in the world, was named in honor of its inventor and began production in 1907.   See below for the 1900 patent.

The first of many Bakelite satellite companies worldwide, the Bakelite Gessellschaft gmbH, was founded in Berlin in 1910 by Baekeland and two German companies.  Late the same year, the General Bakelite Co. was established in the U.S. by Baekeland.

Two independent chemical research and production companies in the same time period, Redmanol Chemical Co. founded by Lawrence V. Redman after whom the harder, more durable and amber-colored synthetic was called, and the Condensite Co. established by A.J. Aylesworth, developed and sold their products which included substantial differences from Bakelite although they employed the same heat process.  The hard, durable synthetic plastic redmanol was called thus after its developer and is made from the action of formin on carbolic acid.  On the other hand, condensite is formed from the action of chlorine on naphthalene.  In other words, all three have fundamental differences that make them viable as separate synthetic plastic products.

Perhaps seeing the only way to maintain ultimate proprietary control over his original Bakelite idea and not miss out on the opportunity to use newer, better variations on his theme, in 1922 Baekeland sued a distributor of Redmanol, which had a controlling interest in Condensite, for patent infringement.  Baekeland must have known the other companies could not fight the complaint in court and maintain production.  His civil action ending in success, he “arranged” for the two smaller chemical concerns to be consolidated with the formation of the Bakelite Corp.  From then on, Redmanol and Condensite products, including pipes, were stamped Bakelite – but all anyone needed to do was look at the quality of the product to know the difference.  Bakelite Corp. was consumed by Union Carbide and Carbon Corp. in 1939.

Redmanol so approximated the appearance of amber – which, remember, was prized in meerschaum and other pipes before and after the turn of the 20th century – for which Redmanol Chemical Products in its own name took out ads like one in the June 1919 issue of “The Scientific American.”  High-minded and overblown, as was the custom of the day, the ads were headed, “In Search of the Man Made Amber.”r1 r2 r3This amazing combination of all that one could hope to find in a pipe – artistry, elegance, refinement, style, class and functionality, to name a few attributes – alas does not belong to me, and I will neither hesitate nor pretend not to be jealous of the fact.  Instead, my fellow piper and friend, Darryl Loomis, is the very lucky new owner.  He loves it so much that he was willing to tolerate a somewhat bad taste he detected rather than trust it to someone to restore.  I am honored to clean it up for him.  Shocked to find I have no photo of Darryl, I suspect he will not be unhappy.

Darryl asked me to clean it up.  Well, the fact is, I got one look at it and could almost not keep my voice under control when I said I would love to do it for him if he had no plans for the project.  I admit I was jazzed to be able to take it home with me from Friday night’s local pipe get-together at the tobacconist.  But there’s one important thing I should now note about any pipe “cleaning” job I undertake, unless the owner makes it clear that’s all he wants done, period.  I don’t half-ass anything.  Even when my business site was up (and it will be again this week), I included basic refurbishing with cleaning jobs and the full works with refurbs/restores (any necessary replacement parts not included in the base price).  So that’s what’s happening here.

While we talked about the pipe, Darryl mentioned something peculiar.  He said he noticed a somewhat bad taste but seemed willing to tolerate it as he did not expect to rotate this pipe very often.  I unscrewed the bowl from the shank and saw right away where some of the unpleasant effect may have originated, but mentioning it to him, he was emphatic that he had heard the metal plate inside the shank (just as with any standard system metal, interchangeable bowl pipe such as a Kirsten) was coated with an unknown substance to keep it from overheating.

Being somewhat more curious than usual, after I was home with the pipe, I ran a cleaner through it, loaded a half-bowl of MacBaren 7 Seas Red cherry and lit up.  Very soon the nastiness Daryl had understated rose in full force, ending with such awful dottle I spat it into a handy cup.  My tentative conclusion, until I can query Daryl more, is that he trusted the person who sold it to him and didn’t considered it might never have been cleaned.

Now, for the before photos of this gorgeous, unique Kaufman Brothers & Bondy work of art – a pipe with a screw-in bowl that predates Kirstens by more than two decades.r4 r5 r6 r7 r8 r9 r10 r11 r12 r13RESTORATION

I removed the bowl and began there.  Having come across a couple of Reborn Pipes blogs, one by Troy Wilburn a year ago about a KB&B Blue Line Poker c. 1909-1914 and the other by Steve Laug concerning Redmanol bits from almost four years back, I was prepared for how to deal with the briar bowl as well as cleaning the deep red quality synthetic plastic, the cubic zirconia of the phenol formaldehyde resin world.

Steve had used nail polish remover (acetone) as a less invasive way of stripping the stain, and it worked quite well of course.  Not having any of the stuff on me, however, and being short on cash and time to do this job for gratis, I compromised.  Instead of a long, thorough soak in Everclear, I dunked the bowl in a tiny Tupperware container for a minute, removed it and scrubbed it dry inside and out with a soft cotton rifle cleaning cloth.  I did have to repeat that process, but still, the combined soak time was minimal.r14 r15 r16 r17Again I regretted not being able to follow Steve’s lead using a Pipnet reamer because I saw the good reasoning behind it…BUT, my handle broke some time ago, rendering it useless.  You get what you pay for.  Next time, I’ll invest a little more for a lot better.  But just a couple of turns of the Senior followed by 500-grit and 320 paper made the chamber baby smooth and clear of char.  I also used the 320-grit on the rim to remove some scrapes, and both papers on the bottom side which was rougher from after wear from repeated turning into the grooves of the shank.r18 r19 r20I ran a few cleaners dipped in freshener through the bit’s air hole, the first of which came out filthy, but the end result was clean.r21Next, I used wet micro mesh from 1500-12000 on the entire surface of the Redmanol shank and bowl cup.  The minimal blemishes there made that fast work.  Cleaning out the draught hole was trickier with more cleaners dipped in freshener, but the accreted gunk and juice all came out.  I tested it again later to be sure, but it was clean.  I really don’t like not being able to retort any pipe.r22 r23Near the end, I stained the pipe bowl with Fiebing’s Brown, flamed it and after it cooled gave it a gentle 3200 micro mesh buff.  I was very pleased with the color I got from the wood.r24The bell tolled the time to do that which I had put off and Steve graciously reminded me needed doing.  He suggested a little Super Glue around the sharp edges of the Redmanol ledge where the bowl was to fit would fill in the cracks.  That followed by micro mesh or light sandpaper would do the rest.  Here is the best before shot I could get with my failing flash system, but the cuts on the right side of the synthetic plastic show up well enough.  There was a matching pair on the left side, suggesting the pipe’s enjoyer was screwy in his habits or the bowl never quite fit right.r25Here’s a shot I admit is horrible with the Super Glue applied, and one after it dried.  I opted for super fine “0000” steel wool to even off the ledge.r26 r27I really can’t say what those apparent white flecks are other than that I took it in a hurry outside.

Not touching the bit with any kind of wax, I buffed the briar bowl with white Tripoli, White Diamond and carnauba.

r28 r29 r30 r31 r32 r33 r34 r35CONCLUSION

For this special pipe, instead of my usual last photo being the left side full shot, after a detail picture of the band’s KB&B stamp, I chose the close-up of the wonderful red translucence of the bit held up to the light by a friend.  The old I would have tried to take it myself despite having to hold down the flash pop-up at the same time, and the probable end would have been, well, unthinkable.  But I love those flashes, sparkles and twinkles that make the lovely amber-like bit, which is often called Bakelite because of its more famous owner, so scintillating.

HOLD THE PRESSES!  At the exact moment I was about to hit SEND and dispatch the blog to Steve, I made a connection between Redmanol and a meerschaum-lined art-deco style bulldog Chuck sold me some time back with a bottom he described as what I thought was “red menaul,” or something to that effect.  Now I understand what it was.r36

Here I’ve had this great, smooth and cool smoking pipe in my collection for several years and never knew what to call it.  All mysteries come to an end in time.
