This Interesting Old Keyser Hygienic Patent Bent Billiard Was Clogged and Unsmokeable

Blog by Steve Laug

This next pipe is another that has been here for a very long time. I have no idea where I purchased it or whether it came to me in a trade for labour. I don’t remember. I have worked on quite a few of these English made Keyser Hygienic Pipes over the years and know that they were made for the South African market. They were unique in that one stem pretty much fit all of their models. They have a unique system in the shank end – a tube that aligns with a tube in the stem. The aluminum mortise acts as a cooling chamber. This particular pipe has some nice grain and a few fills in the heel area. There is a shiny top coat on the pipe – varnish I think. The aluminum was dull. The bowl had been reamed but the pipe otherwise was filthy. I could blow air through the stem but not through the bowl and shank. It was clogged and unsmokeable. The rim top was quite clean and the inner edge was damaged on the front with darkening and burn marks. The stem was chipped on the end that fit in the shank and was missing a small chunk. The top and underside of the stem was covered with deep tooth marks. Internally it was filthy with build up in and around the tube inside. The pipe smelled like older English tobacco. I took some photos of the pipe to give a sense of what I saw before I started. I took photos of the rim top and inner edge of the bowl to show the burn damage and darkening there. I also tried to capture the chipped end at the place it inserts in the shank and the tooth marks in the stem on the top and underside of the stem just ahead of the button. I removed the stem from the shank and took a photo of the pipe to give a sense of the proportion. I tried to capture the “plumbing” in the shank and in the stem. The inner tube in the shank was straight and the tube in the stem was aimed downward. The mortise acted as a cooling chamber. You can also see the chip missing from the end of the stem. I also had some saved advertisements on the system that I have included below to show how it works. It is a unique pipe.It is stamped on the left side of the shank and reads Keyser [over] Hygienic [over] Patent. On the right side it is stamped Made in England. There was also long patent number stamp in the inside of the aluminum shank extension. I am including two links below. The first is to a blog I wrote on a Keyser Bent Billiard that is very similar to the one on the table now. It is a good read in terms of history and detail on the brand (https://rebornpipes.com/2018/09/27/restoring-a-keyser-hygienic-patent-from-a-garden-shed-in-england/). The second one is to a pamphlet that I have on rebornpipes about the brand. It is a classic piece of old advertising (https://rebornpipes.com/2018/10/01/keyser-hygienic-pipes-pamphlet/). Give it a read.

Now it was time to work on the pipe. I decided to address the blockage in the airway from the shank to the bowl. I worked many pipe cleaners through but was not able to break through at all. I finally used a straightened paper clip and carefully worked it into and around the inside of the airway and was able to break the clog. It took quite a bit of probing with the clip to finally remove the blockage and give the bowl good draught but once it was open it was great. I cleaned out the chamber in the shank and in the stem as well as the airways in both with pipe cleaners, cotton swabs and Isopropyl 99% alcohol. Many pipe cleaners and much time passed and the draught was clean and open in both the stem and the shank. With the bowl and shank clean I moved on to repair the shrunken fills in the heel. I used the tip of a Maple and black stain pen to darken the putty spots before putting a drop of clear CA glue on top to fill them in. Once the repairs cured I sanded them smooth with 220 grit sandpaper to blend them into the surface of the bowl. While they are dark spots and look quite large at this point once I work them over with micromesh they will be smaller and a bit lighter. With that done I worked on the burn damage and darkening on the inner edge of the rim. I used a folded piece of 220 grit sandpaper to give the edge a light bevel to minimize the damage and bring the bowl back to round. I polished the bowl and rim top with micromesh sanding pads – dry sanding it with 1500-12000 grit pads. I wiped the bowl down with a damp cloth after each pad to remove the sanding debris. After the final sanding pad I hand buffed it with a cotton cloth to raise a shine. I worked some Before & After Restoration Balm into finish of the briar with my fingertips to clean, enliven and protect it. I let the balm sit for a little while and then buffed with a cotton cloth to raise the shine. The Restoration Balm really makes the grain stands out beautifully. I set the bowl aside and turned my attention to the stem. I used a topping board to smooth out the chip on the right side of the stem. To do that I flattened the end and reduced the diameter of the stem to fit more smoothly into the shank of the pipe. I filled in the tooth marks on both sides of the stem with clear CA glue. Once it cured I flattened out the repairs with 220 grit sandpaper (I forgot to take photos of this step). I polished the stem with micromesh sanding pads – wet sanding with 1500-2400 grit pads and dry sanding with 3200-12000 grit pads. I wiped the stem down after each pad with Obsidian Oil. I polished it with Before & After Pipe Stem Polish – both fine and extra fine and buffed it with a cotton pad. I gave it a final coat of Obsidian Oil and set it aside to dry. I carefully polished stem with Blue Diamond to polish out the remaining small scratches. I used a very light touch so as not to damage the stem. I buffed the bowl with Blue Diamond as well – a bit more vigorously. I gave the bowl and the stem multiple coats of carnauba wax. I buffed the pipe with a clean buffing pad to raise the shine. I hand buffed it with a microfiber cloth to deepen the shine. The pipe polished up pretty nicely. The grain came alive with the buffing and works well with the polished aluminum ferrule and the polished black vulcanite stem. Altogether the pipe has a rich look. The finished pipe is shown in the photos below. The shape, finish and flow of the pipe and stem are very well done. The dimensions are Length: 5 ½ inches, Height: 1 ¾ inches, Outside diameter of the bowl: 1 ¼ inches, Chamber diameter: ¾ of an inch. The weight of the pipe is 1.55 ounces/44 grams. I will be gifting this pipe to a good friend of mine who I think will appreciate cool smoke the pipe delivers. Thanks for walking through the restoration with me as I worked over this well-made Keyser Hygienic Bent Billiard Patent pipe.

Keyser Hygienic Patent Pipe

Over the past year I have been picking up these Keyser Hygienic pipes on EBay. This one makes the third one I have picked up at a reasonable price. They are made in England and sold exclusively in South Africa. The word is that they were designed to be virtually indestructible for farmer pipe smokers in SA. All versions of the pipe have the same stem – one size fits all. They seem to be made of nylon and rubber or some combination. They are tough and take tooth wear very well. Two of the three I picked up are older and both had the original stems on them. They had tooth chatter and minor dents. Steaming would not raise the dents at all. I had to deal with them with sandpaper and micromesh sanding pads.

The photo below came from the web and pictures a cutaway picture of the pipe and the unique condensing chamber that makes up the patented portion of the pipe. The shank has an aluminum condensing chamber with a tube in the centre that lines up with the tube inside the stem. It is pointing downward so air swirls around in the chamber formed by the military bit stem and the shank. Moisture is trapped and the smoke is cool and dry without loss of flavour.

The pipe I am working on this time is a pot shaped sand blasted pipe. The aluminum was oxidized and dull the blast was dirty and the crevices filled with dirt and grime. The stem was in pretty clean shape other than the tooth chatter near the button. The rim of the bowl was tarred and caked. The cake was uneven and tapering in the bowl – almost as if the bowl was only half filled and smoked that way the majority of the time. The upper portion of the bowl had a very thin layer of cake and the lower portion a thick uneven cake. The condenser in both the stem and the shank were filled with a dark brown tar and the airway was constricted in the shank and clogged in the stem. The photo below shows the condition of the bowl and the stem and highlight where the work would be needed to clean up the exterior of this pipe.

I reamed the bowl back to bare briar and scrubbed the blast surface with a brass tire brush to clean out the crevices. I also used a soft bristle tooth brush to finish cleaning the surface off. Once that was done I put the bowl in the alcohol bath to soak while I worked on the stem. The next two photos below show the stem after I used 240 grit sandpaper to remove the tooth marks and slight dents. I then used micromesh pads from 1500-6000 grit to polish the stem and work out the scratches. I have learned the hard way that you cannot buff these stems on the buffer as a little bit of surface heat from the buffing pads melts and distorts the surface. So these stems are totally buffed and polished by hand.

The next two photos show the stem after it has been sanded up to the 3200 grit micromesh pad. The stem is beginning to get a shine and the scratches are disappearing with the sanding. From this point I went on the sand the stem through the remaining micromesh grits and when finished I gave it a coating of Obsidian Oil to penetrate the surface and give it a deep polish. Once that dried I buffed it by hand with some carnauba wax in paste form that I purchased from Walker Briar Works.

From the next series of photos you can see that I interrupted my work on the stem to remove the bowl from the alcohol bath. I did that because I was curious to see how it was cleaning up. You will notice in these photos the brownish grey sludge in the grooves of the blast. I used the tooth brush once again to scrub the surface with Isopropyl from the alcohol bath. Once the grime was removed I washed the bowl down with clean Isopropyl and dried it off.

The next series of photos show the dried bowl. The grime is gone and the finish is now down to the stain. Even some of the top coat of stain has been removed and you can see the briar. I laid the bowl aside and finished up the stem as I described it above.

The aluminum condensing chamber on the shank and the chamber in the stem needed much work. I used cotton swabs that I flattened to clean the area inside the shank around the airway extension and the same in the stem. Once that was clean I polished the oxidized aluminum with the micromesh pads to burnish the aluminum and get the shine back.

I then restained the bowl with a dark brown stain, knowing that when I buffed it the reddish brown undercoat would shine through on the high spots and the dark would fill the crevices and give the pipe a contrast stain. The next series of three photos show the staining and the way the various grains took the stain. The right side of the bowl has a great ring blast that is fairly deep and craggy. The left side is more of a blast on birdseye. It is an interesting looking blast. The bowl rim came out clean as well and shows an interesting contrast in the light of the flash.

The final series of four photos show the finished pipe. The entirety has been given a coat of wax. I used Halcyon II on the blast to polish it without leaving the white residue in the grain of the blast when it dried. I buffed it by hand. The stem received another hand applied coat of carnauba wax and a buff by hand. The pipe pictured is clean and ready to smoke.

I have included pictures below of the other two Keyser pipes that I picked up and refurbished. The top one is an apple with really nice grain. I have been smoking this one and enjoying the dry and cool smoke that it gives. The second is a smaller prince shape that is no longer available. It had some burns on the rim that are still visible but it too smokes very well. One day will rework the rim a bit and minimize the burn marks. Till then I will smoke these Keyser’s and keep an eye for more of them.
