Reconstructing a Broken Stem on Dunhill Bruyere # 51671


Blog by Paresh Deshpande

I had just finished the first of the 30 pipes from my Mumbai Bonanza find, a Stefano “EXCLUSIVE”; here is the link to the write up; https://rebornpipes.com/2019/03/11/mumbai-bonanza-stefano-exclusive-restorationa-month-long-project/

How did I land up with this lot makes for an interesting read and one which I have written about in the above restoration. Here are pictures of the pipes that I received in this lot. This lot contains some very nice collectible pipes, a few well known brand pipes and some mediocre pipe brands. Overall, with seven Dunhills, a Preben Holm #1, a couple of Made in England Pete System pipes, Charatan’s and other assorted pipes, I would say that I had hit a huge jack pot!!! Hence, I like to call this find as “Mumbai Bonanza”.

The pipe that I decided to work on is from this find and is marked in a red circle in the picture below. The stummel surface boasts of some beautiful bird’s eye grain on either side of the stummel while densely packed cross grain adorns the front and back of the stummel and also the shank top and bottom surface. It is stamped with “# 51671” towards the bowl and followed by “DUNHILL” over “BRUYERE” on the left side of the shank while the right side bears the COM stamp “MADE IN” over “ENGLAND” followed by underlined numeral “19”. Dunhill White Dot adorns the top of the vulcanite stem. The stampings on either side is deep, crisp and clear. The dating of this pipe is very straight forward and dates to 1979 (1960+19). However, deciphering the shape code, 51671, proved to be a challenge. The first digit 5 identifies this pipe as being Group size 5, second numeral, 1, identifies the style of mouthpiece as being tapered and this is where the ease ends and led to a lot of confusion with the next two digits. Though the shape appears as Zulu, it is not so since the shank is rounded. The profile of the pipe points towards it being a Horn shaped, but the shape code supports neither a Zulu nor a Horn!!! Well, another mystery which is likely to remain unresolved!!

With this information, I proceed ahead with the restoration of this handsome pipe, my first ever DUNHILL!

INITIAL VISUAL INSPECTION
The chamber is clean with a thin layer of cake which indicates that the pipe has been kept clean by its previous Steward. From what I can see, the chamber walls appear to be without any damage. The chamber is odorless. The inner rim edge show minor unevenness which should be easy to address. It is the outer rim edge that shows significant damage on the left side in 7 o’clock and 11 o’clock directions. This must have been caused due to hammering of the edge against a hard surface to remove dottle!! The rim top surface has a number of dents due to the same reason. The mortise is clean and so is the shank airway. The stummel surface is peppered with numerous dents and dings and scratches. Being a Dunhill, any issue of fills is never to be expected and hold true for this pipe too. These dents and ding are probably caused due to uncared for storage by the previous Steward and further contributed to by the trash collector who had sold the pipes to me. The stummel is covered in dirt and grime and is surprisingly slightly stick to the touch. The briar looks lifeless and dull which is nothing serious to address. The vulcanite stem shows significant damage to the button end, in fact, there is no button at all!! The stem end is missing, well, about half an inch of vulcanite. Heavy and slightly deep scratches can be seen extending upwards from the broken button side. The stem surface is very thin at the place where it has been chewed off by the previous owner. I intend to reconstruct/ rebuild this portion of the stem, including the slot, while maintaining the stem and general profile of the pipe. This will require major repairs. The quality of vulcanite is good. In this project, repairs to the damaged outer edge and stem rebuild will be a major challenge, the stem more so, as maintaining the tapered profile of the stem will need to be adhered to for overall appeal of this piece of briar. Having just finished the tedious restoration of the Stefano, I am aware of the challenges this restoration will be presenting enroute.

THE PROCESS
Since the stem has significant damage, and from my experience of stem repairs (Stefano nightmare!) this will be the most time consuming and laborious part of this restoration, I start this project by tackling the stem first. I was faced with two options in my approach to this stem repair; first was to recreate a new button around the broken part and maintain the existing stem profile with a straight slot and the second option was to cut away the damaged button and reconstruct an entirely new button with a straight horizontal slot, sacrificing the overall length of the pipe. I decided to take the former approach. This decision was partly dictated by the fact that I do not have a rotary cutting blade to cut the damaged button end and partly to my innate desire to maintain the originality of the pipe. It’s a Dunhill after all!!

Now that I was clear about the path to be followed, I sand the stem end with a folded piece of 220 grit sand paper to erase the scratches and provide a smooth surface for the intended fill. I cleaned out the internals of the stem with hard bristled and regular pipe cleaners dipped in isopropyl alcohol. Once I was satisfied with the internal cleaning, I wiped the stem surface, particularly the damaged button end, with a cotton pad and alcohol to remove any traces of dirt and grime. To begin the stem repairs, I smeared a folded pipe cleaner with petroleum jelly and inserted it in to the stem airway. I prepared a mix of CA superglue and activated charcoal and generously applied it over and extending beyond the broken surface and set it aside for curing over night. To be honest, I have not researched and measured the exact length that I had to reconstruct, but eyeballed the length using the longer left side of the stem (where a very tiny raised portion of the button is still visible) as a guiding length. Before moving ahead, I would like to mention here that I had applied this mix in layers, over the week, to achieve sufficient thickness which would help during the filing and sanding while shaping the button and achieving the correct stem profile. Once I was satisfied that the fill had cured nicely, I moved ahead and began the process of filing and shaping the button end with a flat head needle file. And then this happened… As you can see in the following pictures, not everything was lost. There remained a portion of the fill which was intact. Not one to give up and having the experience of the Stefano behind me, I persisted with the reconstruction. I made a fresh mix of activated charcoal and CA superglue, this time around increasing the amount of superglue, and reapplied it over the broken button end after inserting a petroleum jelly smeared a folded pipe cleaner. I continued with the layering technique of building up the fill.The next set of pictures show the progress of the stem rebuild using the layering technique. Slowly but surely, I am getting there!Once I had achieved the desired thickness and having let the fill cure for a few days, I proceed with shaping the button using flat head needle files. I am quite pleased with the way things are progressing at this point in restoration. However, fingers remain crossed and mentally remained prepared for disaster to strike anytime. At this stage, I am pretty satisfied with the profile of the stem, the thickness of the button and, in general, the overall progress on the stem rebuild. Also glad that there have been no further setbacks!!!! With this I proceed to shape the horizontal slot for the button. It is a long drawn process and a tedious one at that!! The inside of the slot needed to be smoothed out while maintaining the thickness of the button edge on either side. I build up the insides of the slot by layering it with superglue, letting it cure, sanding and then applying a fresh layer. I must have repeated this process for good about a week plus!!!! The external surface of the slot was also developed the same way and this helped in maintaining the thickness of the button edge.While the stem repair was progressing at its own pace, I moved ahead to deal with the stummel repairs. Given the size of the chamber, I reamed the chamber with size 4 head of a PipNet reamer. The cake was thicker at the bottom and used the size 2 head to remove the cake. I used my fabricated knife and scraped out all the remaining cake. The amount of cake reamed out of the chamber really surprised me as I was expecting minimum cake. I further used one folded piece of 180 grit sand paper to sand out the last traces of remaining cake and expose the walls of the chamber to ascertain that there are no cracks/ heat fissures. I wiped the chamber with a cotton pad dipped in isopropyl alcohol to remove the carbon dust left behind by all the reaming and sanding process. The walls of the chamber were solid with no damage. This was followed by cleaning the mortise by scraping away at the dried gunk with my fabricated spatula and followed it up with further cleaning using cue tips, pipe cleaners and shank brush dipped in isopropyl alcohol. This eliminated all traces of old smells from previous usage. Continuing with the cleaning regime, using a hard bristled tooth brush dipped in undiluted Murphy’s oil soap, I very deliberately scrubbed the surface of the stummel and the rim top. The original reddish dye was also washed away to some extent. The stummel and rim top was dried using paper napkins and soft cotton cloth. I set the stummel aside to dry out naturally. The damages to the outer rim edge, uneven inner rim edge and stummel dents and dings are now clearly visible in the above pictures after the cleaning.

Next, I decided to address the dents and dings on the stummel surface and the damage on the rim outer edge by steaming them out. I heated my fabricated knife over the flame of a candle, placed a wet Turkish hand towel over the damaged areas and steamed out the dents by placing the heated knife over the towel. Though some dents were still observed, these were greatly reduced when compared to before steaming. The steaming method had raised to the surface all the major dents and dings. However, the outer edge of the rim still remained unaffected. The steaming method having failed to address the issue of the damaged outer rim edge, I decided to use a more aggressive method of topping the rim top. Personally, I prefer to avoid topping as I do not appreciate loosing even one mm of briar estate, but in this instance, I was left with no recourse but to top the rim. I topped the rim on a 220 grit sand paper, checking frequently the progress being made. The damage to the outer rim was so extensive that the even after what felt like ages of topping, the damage was still apparent. Finally, I just did not feel like topping any further and hence decided on another course of action. I would rebuild the outer edge with briar dust and superglue. Having decided on this course of action, I lightly top it on 600 grit sand paper to reduce the sanding marks left behind by the 220. The only benefit derived from this topping was that the inner rim is now perfect and I collected some briar dust!

I tried mixing briar dust with superglue, but to no avail. The moment the two came in contact with each other, the mix hardened. So I resorted to the layering method again, first I layered superglue over the damaged surface followed by sprinkling of briar dust and one final layer of superglue. I set the stummel aside to cure. The only problem with this method is the high probability of presence of air pockets.The next evening, the repairs to the edge had completely cured and I move ahead by filing and rough shaping with a flat head needle file. I further fine tune the blending by sanding it down with 220, 320, 600 and 800 grit sand papers. Here is how the repaired area appears at this stage. I am very pleased with the way this repair progressed.Steaming out the dents and dings from the stummel surface had necessitated that the surface of the stummel be evened out by sanding. I sand the entire stummel using 220, 400, 600 and 800 grit sand papers. The little dents and dings that remained on the stummel and outer rim edge were also evened out under this sanding process. This was followed by polishing with micromesh pads. I wet sand the stummel with 1500 to 2400 grit pads and follow it up by dry sanding with 3200 to 12000 grit pads. I wiped the surface with a moist cotton cloth after every wet pad to check the progress. The repaired rim edge now appears shiny and glossy. This has got me a bit worried as it stands out from the rest of the stummel surface. I fervently pray that this is masked after I have stained it. I rub a small quantity of “Before and After Restoration Balm” in to the briar with my finger tips and let it rest for a few minutes. The balm almost immediately works its magic and the briar now has a nice vibrant appearance. I further buff it with a horse hair shoe brush. I had hoped that the balm would work its magic on the filled area and help in blending it a bit, but that did not happen. I had simultaneously been working on the stem reconstruction by building up the slot and button using the layering technique. Though tedious, I have reached a satisfactory stage from where I can fine tune the slot and button edges. What followed were hours of tedious, back breaking and nerve wracking process of sanding and shaping of the slot and the button. Though the slot is not a perfect horizontal straight opening, rather a slight oval, I have managed to match the profile and dimensions of the original stem and the pipe is definitely smokable. Here are pictures of the progress.For a better blending, I further sanded the entire stem with 220 followed by 400, 600 and 800 grit sand paper. This helps to reduce the sanding marks left behind by the more abrasive 220 grit paper. To bring a deep shine to the vulcanite stem, I went through the complete set of micromesh pads, wet sanding with 1500 to 2400 grit pads and dry sanding with 3200 to 12000 grit pads. I wiped the stem with alcohol after each pad and rubbed it down with Extra Virgin Olive oil to rehydrate the vulcanite. The repairs have blended in very well and the stem now looks a shiny black and beautiful. The internals of the stem was cleaned out using alcohol and pipe cleaners. The finished stem is shown below. I kept the stem aside to let the stem absorb the oil and turn my attention towards the stummel. I decided to stain the stummel in cherry red stain which was the original stain true to the Bruyere line of Dunhill pipes. I use the powder variety of stain and mix it with 99% isopropyl alcohol. I heated the stummel surface with a heat gun and applied the stain with a folded pipe cleaner. As I paint the stummel with stain over sections at a time, I burn the dye using a Bic lighter that combusts the alcohol in the aniline dye and sets the dye pigmentation in the wood.  After fully saturating the stummel and covering the whole surface, including the rim top, I set the stummel aside to rest for several hours. By next evening, the stain had set nicely. I mount a cotton cloth buffing wheel (because I do not have felt cloth buffing wheels!!) on the Dremel and set the speed at about 40% of full RPM and apply red compound to the stummel. This does help in revealing the grains gradually; however, my fears had come true. The repairs to the outer edge of the rim did not absorb the stain and is encircled in yellow. To finish, I re-attach the stem with the stummel. I mounted a cotton cloth buffing wheel to the Dremel (actually it is not the brand machine, but a local machine which is similar).  I set the speed at about half of the full power and applied White Diamond compound to the entire pipe. I wiped/ buffed the pipe with a soft cotton cloth to clear it of any leftover compound dust. I then mounted another cotton cloth wheel on to the polishing machine and applied several coats of carnauba wax. I finished the restoration by giving the entire pipe a rigorous hand buffing using a microfiber cloth to raise the shine further. The completed pipe looks lovely, fresh and vibrant; the photographs in this case, do not do justice to the appearance of this beautiful pipe, my first Dunhill. I cannot thank enough my friends Mr. Dal Stanton, Mr. Sam Vior, Mr. Victor Naddeo and Mr. Steve for helping me to research and complete this mysteriously stamped Dunhill pipe. PS: The readers would have observed the fact that the rim repair could not blend completely in spite of my best of efforts and still I have highlighted the flaw while the general tendency is to hide it. True, there are reasons for me highlighting the flaws; firstly, if I cannot hide it from myself, than why attempt to pretend it’s not there and secondly, the highlighting will encourage you to have a closer look at the flaw and maybe you could have an explanation for it in the first place and share it with me. This will help me in avoiding these mistakes in my future restorations. Third and most important reason is that a newbie somewhere who is not so fortunate like me to have friends and mentor that I have will also benefit from my mistakes.
