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.

Restoring a Unique Edition of the Keyser Hygienic System Pipe

I picked up this Keyser Hygienic on EBay because it caught my eye. I have three other Keyser Hygienic pipes and they are all very similar in terms of the system. They are briar bowls and shanks with an aluminum mortise with a tube in the centre running to the airway in the bowl. This is matched with a military mount stem with a tube with a down turn on it that fits into the airway in the mortise. The swirling smoke rolls around the inside of the mortise where the moisture in the smoke condenses on the sides of the aluminum mortise. The cooled air is drawn into the down turned tube in the stem and it delivers a cool, dry smoke. The system is fairly straightforward and simple. The genius of the design is that any stem fits any pipe of the same size. Replacement stems are easily purchased and all that is necessary is the size of the pipe and the replacement will be a ready fit.

But this new Keyser was unique in all ways. The system design seems like a prototype of the original or maybe a step toward the ones that I have. It is composed of a short shanked briar bowl and a metal tube that has a normal vulcanite tenon. This sits in the shortened shank. Inside the tube is a second tube that extends ¾ of the way up the barrel. The inner tube is the extension of the airway in the tenon. The stem is a short pressure fit stem with a shoulder that allows it to ride on the end of the outer tube. On the end of the stem is a down turned short tube that draws air in to the mouth piece from the condensing chamber of the tube. It is a fascinating design. It is that uniqueness that caught my eye – that and the stamping/engraving on the outer tube which reads as follows:

The next series of seven pictures shows the pipe as it appeared in the EBay webpage. The seller did a great job describing the current state of the pipe and the areas of concern. The seller notes some of the scratches on the outer tube and the darkening of the rim. He also noted the tooth chatter and scratch marks on both the top and underside of the stem.

When the pipe arrived I unpacked it and examined it. There were indeed tooth chatter/marks on both the top and bottom of the stem. There was a cigarette burn mark on the bottom of the shank where it meets the bowl. It was not a deep burn and there was no charred wood just a dark mark. The rim itself also had some issues. While the surface was not charred there was a burned area on the front inside of the bowl and on the front outside of the bowl. It looked to be damage from a lighter used in the same place repeatedly over time. The remainder of the finish was in pretty good shape but the entire pipe would need to be stripped in order to address the burn marks on the rim and the side of the shank. The inside of the bowl and shank were very clean. The pipe had not been reamed but there was a light cake that smelled like an aromatic. The barrel was tight on the shank but I carefully was able to remove it. The vulcanite tenon on the end of the barrel was undamaged but the airway was closed in with tars. The way the tenon was attached to the barrel was interesting. The end of the barrel was bonded to a circular plug of vulcanite with the tenon an integral piece of the part. The stem was frozen in the barrel and could not be removed. The button on the stem was unmarked and the tooth marks were actually mid stem on the top and bottom sides. The vulcanite stem was oxidized and would need to be cleaned. The next four photos show the items that I have pointed out in this paragraph.

I was able to remove the barrel and tenon from the shank of the pipe by carefully twisting the barrel free of the shank. I always hold tightly to the shank with one hand right next to the shank and then twist with the other hand. I try to maintain equal pressure on all points so that the shank is not strained or cracked in the process. The next photo shows the tenon on the barrel. It is almost the same length as the shank and the airway is lined up very closely to the airway in the bottom of the bowl. I cleaned out the mortise with cotton swabs and Everclear and found that it was quite clean. I also cleaned out the barrel from both ends but was not able to get a pipe cleaner to go all the way through the pipe from button to tenon.

The next three photos show the front of the bowl and the extent of the burn marks on the front outside of the bowl and the front inside of the rim. These were two areas that would need to be worked over to minimize the burn marks on the finished pipe.

I used my PipNet reamer to ream out the soft aromatic cake in the bowl and then recleaned the shank and the inside of the bowl with pipe cleaners and Everclear to remove the carbon dust that came from the reaming process (Photo 1 below). I wiped down the outside of the bowl and shank with a cotton pad and acetone to remove the finish on the pipe (Photo 2 below).

The next series of fourteen photos show the topping of the bowl to remove the burned area on the inside of the rim and the front outside edge. The burn had rounded the outside edge and made it appear out of round when looking at it from the top. I wanted to top the bowl enough to bring the top view back into round, minimize the wood damage in both spots and clean up the sharp edge of the bowl. I used two different sanding sponges – medium grit (black coloured sponge) and a fine grit sponge (yellow coloured sponge) both pictured below to start the process. I went on to use medium grit emery paper on the hard board to further top the bowl and ended with 320 grit sandpaper on the board. I polished the finish of the topped pipe bowl with the fine grit yellow sanding sponge. I also worked on the burned area that extended down the front of the bowl with the two sanding sponges.

While I was working on the bowl I put the barrel and stem unit in the freezer to try to break loose the stuck stem. I have found that the varying contraction time of the metal and vulcanite will often loosen the stem. Once it was in the freezer for 30 minutes I could easily remove the stem and give the inside of the barrel and the stem a thorough cleaning with pipe cleaners and cotton swabs dipped in Everclear. I cleaned them until both came out clear. The next five photos show the broken down stem and the tube on the end of the stem that I was talking about above. There is one photo of the barrel but it is too dark to see the inner tube.

Once the stem and barrel was clean it was time to deal with the tooth marks and chatter on the stem itself. I sanded the top and the bottom with 320 grit sandpaper to remove the marks and the chatter. None of them were too deep. They were more of a ripple like effect on the surface of the vulcanite. I sanded them flat to the surface of the stem and then went on to sand the stem with micromesh sanding pads from 1500-12,000 grits. The next four photos show the progress of the shine.

After shining the stem with the micromesh I took it to the buffer and buffed the stem with White Diamond and then rubbed it down with Obsidian Oil and finished it with a coat of carnauba wax. I put the stem back in the barrel and lined up the stem with the stamping on the side of the barrel. I gave the entire barrel and stem another coat of carnauba wax and hand buffed them. The next three photos show the assembled barrel and stem unit polished and ready to put on the bowl once it was restained and ready.

I sanded and resanded the bowl with fine grit sanding sponges and then sanded it with micromesh sanding pads from 1500-3200 grit. I wiped it down with acetone between sandings and again when I was finished to prepare it for staining. The next three photos show the prepared pipe ready for staining. The burn mark on the bottom of the shank is gone with very little sanding and no change to the shank surface itself. The one on the front of the is minimized and the one on the rim is also virtually gone. The bowl is ready for a new finish coat.

I restained the bowl with an oxblood aniline stain, flamed it and restained and reflamed it. I rubbed it down with a cotton terry cloth to smooth out the stain and then took it to the buffer. I always buff with my thumb in the bowl to ensure that the buffer does not grab the bowl from my hand and launch it against the wall. I rotate it slowly in my hand and with a light touch buff the shank. I am careful not to apply too much pressure and round the shoulders on the shank. I normally do not buff with the stem off the bowl but in this case I did not want to risk buffing off the black paint on the barrel so I chance the buffing on the bowl alone. The next three photos show the buffed bowl before polishing.

I reassembled the pipe and then hand buffed it with multiple coats of carnauba wax and polished it with a shoe brush. The stem and bowl have a great shine and the bowl has some beautiful grain on it. I look forward to smoking this one and comparing it with my other Keyser Hygienic pipes. The final four photos below show the finished pipe. I have yet to do the research on the patent information on the barrel but I am hoping to find out a bit of history on this piece.

From the photo of the bottom of the bowl and shank above you can see that the burn mark there is eliminated in its entirety. Also in the photo of the rim above and the one of the front of the bowl below you can see that the burn mark is gone and what remains is blended into the stain.
