Restoring a Rusticated House of Robertson Bulldog with a Clear Acrylic Stem

Blog by Steve Laug

My brother Jeff and I visited an older gentleman near Vancouver, Washington recently and enjoyed a few bowls with him and views many of his pipes. After some viewing and conversation he showed me this House of Robertson Bulldog with a clear acrylic stem and gave it to me as a gift. It is a great looking pipe with a smooth rim top and shank end band. When Jeff and I returned to his home I took photos of it to capture what it looked like when I received it. The finish on the pipe was quite clean and had a great rustication around the bowl and shank. The smooth rim top and edges of the bowl had some wear and tear but was redeemable. There were scratches and nicks around the top and edges on the bowl. The pipe had been topped somewhere in its journey and the front of the cap was lower than the back side of the cap. There was a thin cake in the bowl and the inside was dirty with tobacco debris. The pipe had the House of Robertson etching on the left underside of the diamond shank. The clear acrylic stem fit to the shank very well. The tenon fit well in the mortise. There was some tobacco staining in the airway that would need to be dealt with. There were tooth marks and chatter on both sides of the stem ahead of the button. I took the following photos of the pipe to show its condition before I started my clean up. I took a photo of the House of Robertson etched on the left underside of the diamond shank. It is clear and readable.The pipe has the name House of Robertson roughly hand-etched on the left underside of the diamond shank with an engraving tool. I am including the information that I found when I received my first House of Robertson Pipes a few years ago now. I found a link on Pipedia (https://pipedia.org/wiki/Robertson) that gave me the only information I could find on the brand. I include that in total as it is interesting to read.

“House of Robertson” was in business for many years, but alas, closed their doors in 1999. They were located in Boise, Idaho. They are noted for making rather large and interesting pipes. Thayne Robertson was a Master Mason, AF & AM, and started the shop about 1947 and his son Jon started working there in 1970 when he finished college, along with Thayne’s daughter. Thayne and his son started making the big pipes at that time, and made them together until 1987 when Thayne passed away. Jon kept the store and his sister moved on to other things. The House of Robertson appears to have closed around 1999.

If you would like to read more about the carver, Thayne Robertson I am including a link to a blog I have included on the site. It is fascinating to read and gives some information on the brand.

I thoroughly cleaned up the pipe. I reamed it with a PipNet Pipe Reamer and cleaned up the remnants with a Savinelli Fitsall Pipe Knife. I sanded the inside of the bowl with 220 grit sandpaper wrapped around a dowel. The bowl was clean. I cleaned up the damage to the inner edge of the bowl with a folded piece of 220 grit sandpaper. Once finished it was better. I worked on the back side of the rim top with 220 grit sandpaper followed by a medium and fine grit sanding sponge. I wanted to bring the back of the rim cap down to the same thickness as the front of the rim cap to level out the top. Once it was even it looked much better.I scrubbed the exterior of the bowl with undiluted Murphy’s Oil Soap with a tooth brush. He rinsed it under running warm water to remove the soap and grime. I cleaned out the inside of the shank and the airway in the stem with alcohol, cotton swabs and pipe cleaners. I was able to remove a lot of tars and oils from the shank and some of the darkening in the stem and slot.I polished the smooth rim top with micromesh sanding pads – dry sanding with 1500-12000 grit pads. I wiped the top down with a damp cloth after each sanding pad. It had a rich shine once I had finished. I rubbed the bowl down with Before & After Restoration Balm to deep clean the nooks and crannies of the rusticated finish, enliven and protect the briar. I hand rubbed it with my fingers, worked it into the rings with a cotton swab and into the finish with a horsehair shoe brush. I let it sit for 10 minutes to let it do its work. I wiped it off with a soft cloth. I buffed the bowl with a cotton cloth. It really began to have a deep shine in the briar. I took some photos of the bowl at this point to mark the progress in the restoration. I set the bowl aside and turned my attention to the stem. I sanded out the tooth marks with 220 grit sandpaper and started the polishing of the stem with 600 grit wet dry sandpaper.I polished out the sanding scratches and marks in the clear acrylic with micromesh sanding pads – dry sanding it with 1500-12000 grit pads. I wiped the stem down with Obsidian Oil after each sanding pad. I polished it further with Before & After Pipe Polish – using both the Fine and Extra Fine Polishes. I gave it a rubdown with Obsidian Oil one last time and set it aside to dry. I put the House of Robertson Bulldog back together and worked the pipe over on the buffing wheel using Blue Diamond to lightly polish the stem. I buffed the bowl with a light touch so as not to get any of the buffing compounds in the grooves of the rustication. I buffed the stem to raise the gloss on the vulcanite. I gave the bowl multiple coats of Conservator’s Wax and gave the stem multiple coats of carnauba wax. I buffed the entire pipe with a clean buffing pad to raise the shine. I hand buffed it with a microfiber cloth to deepen the shine. The finished HOR Bulldog pipe is shown in the photos below. The medium brown stains on the rusticated Straight Bulldog with a smooth rim top works well with the clear acrylic stem. The dimensions of the pipe are: Length: 5 ½ inches, Height: 1 ¾ inches, Outside Diameter: 1 ¼ inches, Diameter of the chamber: ¾ of an inch. The weight of the pipe is 36 grams/1.27 ounces. This one will be joining my pipe rack as yet another example of House of Robertson Pipes. I thank my friend in Vancouver, Washington for the gift and will certainly enjoy smoking it very soon. Thanks for following my work on this blog.

Alternative Woods: Refurbishing and Restemming a Black Walnut Pot

I received this pipe bowl as a gift from a friend in exchange for some work I did on one of his pipes. I took it out of the box and put it in the refurbishing box without giving it much of a look. Today I took it out of the box and looked it over. It is well made; the airway is drilled straight and comes out the bottom of the bowl. The drilling is accurate and clean. The mortise is smooth and clean. The bowl has been smoked very little as the bottom half is still fresh wood. The shank is clean and there are no tars. The wood is clean with a few dings and dents. There seems to be a slight finish on the bowl – varnish or something. It also appeared to have a band on the shank originally as there is a stain from the metal on the end of the shank. It came to me without a stem. Today I will take care of that.

I wiped down the bowl with acetone and cotton pads to remove the finish and sanded it with a medium grit sanding sponge. I wiped and sanded until the finish was gone from the bowl and then wiped it down a final time. The smell of the sanding dust as well as the grain told me that I was dealing with a well made walnut, probably black walnut pipe. This one would clean up very nicely.

Since I could not remove the stain left behind by the previous band I decided to reband the pipe. I found a nickel band in my band collection that would be a perfect fit. I heated it with the heat gun and the pressed it into place on the shank. I cleaned up the shank end of the pipe once the band was in place and widened the bevel on the inside end of the mortise to fit the new stem that I would fit for the pipe.

I went through my can of stems and found three different stems that would work with this pipe. Two of them were vulcanite and one was a clear acrylic. I have not done much work with clear acrylic and never turned the tenon to fit a pipe so this one seemed to be the way to go. Each pipe has to be a bit of a learning experience. Besides I liked the way the clear acrylic looked with the walnut bowl and the silver band.

I drilled the airway in the stem to fit the end of the PIMO tenon turning tool and then put the tool on my drill and slid the stem in place. I adjusted the cutting head on the tool to cut off enough material to get a close fit on the stem. The tool is touchy in terms of accurate adjustments so I eyeball it close and then sand it by hand until it fits the shank.

I pushed the stem in place on the walnut bowl and set it down to look at the overall appearance of the pipe. The clear stem was going to work well once I had shaped it to fit. The walnut was already darkening from the oils in my hands. This was going to be a beauty once it was finished.

The diameter of the stem and that of the shank were different. The stem was significantly larger than the shank of the pipe. I used a Dremel with a sanding drum to sand off excess acrylic material. I proceeded with that slowly and carefully as I did not want to nick the band or damage the pipe bowl.

I took the material down as close as possible with the Dremel and then did the rest of the sanding by hand with 220 grit sandpaper. It took quite a bit of time and several return trips to the Dremel before I had the shank and the stem diameter matching. The following photos show the progress on the stem with each one taking it a step closer to the finish.

When I finally had the fit correct with the 220 grit sandpaper I switched to a medium grit sanding sponge to further refine the fit and to remove the scratches left behind by the sandpaper. I finished sanding with the medium grit and used a fine grit sanding sponge to sand the stem again. When finished the stem looked opaque and the shape was done. All that remained was to polish the stem.

Before sanding it further I used a needle file to smooth out the transition in the airway between the stem airway and the place where the drill bit ended when I worked on the tenon. I was able to even out the transition and taper it for a smooth and seamless transition. The walnut was continuing to darken from my hands as I worked on it. I also stopped and sanded the rim of the pipe to remove the deep scratches that were present when I received it.

I wet sanded the stem and the band with 1500-2400 grit micromesh sanding pads and then dry sanded with 3200-12,000 grit pads. I wiped the stem down between each grit of micromesh with a damp cloth to remove the sanding dust and to further polish the stem.

After I finished sanding the stem and the band with the micromesh pads I took the pipe to the buffer and buffed it with White Diamond to further polish it. I rubbed the stem down with Obsidian Oil and when it was dry gave the pipe and the stem multiple coats of carnauba wax and a final buff with a soft flannel buff. The finished pipe is shown below. The bowl has only been given a wax coat and no stain. The finish is natural and I believe that it will continue to darken as it picks up the oils from my hands when I smoke it.
