CBD's Chimney Pots page

Here is a recent set of 3 chimney stack/caps we made to show an example our versatility
This is a project I began on 8-30-04. It is for a local client who live near Downtown Portland Oregon. I had their name and address listed here for over 3 years, but they requested their personal information be removed from our web site (10/07). They have been gradually restoring their house to it's classic look over the last 14 years. It was originally built for a Steam Ship Captain near the turn of the century. She recently ran across our web site and could see how we are capable of making what she was looking for. Here is the picture of what she wanted, but wants us to make them in copper sheet metal instead of a clay tile like this. Beside the fact that this clay one is way too large, being about 6' tall and 2' wide at the base. She needed 3 stacks to go on her one chimney stack. They need to be only 11.75" wide and only 2" apart, so we need to scale it down to fit.
We suggested steeper 8 sided caps for these smoke stacks, and later offered the idea to make the center stack with this sort of Cathedral style top cap, for it would be more interesting than just the 8 sided cone shape caps for the taller center chimney stack. We will be making it in copper with a copper screening over the vents for spark arrest and pest control. The background image of this web page shows the blue painted aluminum templates we had to make, to draw out the patterns on the copper to make the base sections. Then we had to cut the copper pieces out and shape them, as seen below.
Day one (8-30-04)




Day two (8-31-04)

This design and fabrication took us 2 full days of work. As you see this was no simple design to make them with reduced horizontal seams, make it water tight without using caulk or solder because of the heat, and also make it strong, while minimizing the visible rivets.
This is a shot from the underside of the base. The next mid section will have an 8 sided stack that will fit over this section and skirt out at the bottom at a 45 degree angle over the top rim of what we made so far. They will be riveted together and the rings of ornamentation applied over the stacks.
Day three (9-1-04)
These pictures show one of the upper ornamentation being drawn out on the under side of the copper sheet metal. Boy, was that tricky to do the math and design this to be made in one piece.
Here it is all bent and cut, ready for folding. Below is some other angles. Each picture you see here links to a full screen image to see the details better.

Here it is being folded into shape.
I had to hold it in place while Tia drilled the first holes for the rivets to hold that upper ring together. It takes a good 40 rivets just to assemble this ring onto the smoke stack.
This is one of the smaller ornamental rings ready to be installed. There are 2 more behind waiting to be processed. They are riveted on from inside the smoke stack with 12 rivets. I have to first draw the upper line of where it goes. then I drill the rivet holes in the stack just under that line. I them place the ring on the stack and mark the holes to be drilled in the ring from inside of the stack. I then have to remove it to drill the holes in the ring. Then I have to position it on again, line up the holes, and set the rivets. Each one takes about 2 hours to do.


This One Day of E-mail Correspondence (9-1-04)
Here is some of the e-mail correspondence we have exchanged on the first day of this month, half way through project: Date: Wed, 1 Sep 2004 At 01:17 AM 9/1/2004, you wrote: > I can see that these stacks are very complex. Your work is a beautiful piece of art that will adorn our home somewhat like three stacks of a steam ship. It feels like these stacks were meant to be, as I mentioned our house was designed and built by a steamship captain the turn of the century. It does appear that the photo that you sent of the clay pot is three sections. It is interesting to see this stack with a person standing next to it. I now have a better perspective. I look forward to seeing the next section. Thank you for the updates they are much appreciated. I will try and get out to your shop later this week but will call and let you know in advance. Greetings again XXXXXXX, Thank you for your prompt responses. This has helped a lot. I did not know about the Captain, or forgot about that. That is interesting. I was laying in bed this morning and got an idea. I was thinking that instead of all 3 stacks having the same top cap, I could do something like the img_jestateRG2.jpg image file I altered. Only with the outer 2 stacks to have a steeper pitch cap than shown. I have attached a couple photos of a cap I did recently for a teacher in California. They show 2 different 8 sided cap pitches. Try to ignore the bottom section. #27 was for the base of the steeper cap to go on it and support the bottom of the weather vane pipe to go on it. I favor the pitch in #27 for these stacks, so it does not up-stage the center stack. Keep in mind; I do not make this suggestion to make these easier to fabricate. I felt it would make the center one that much more special looking. For some time I was feeling that all three the same, only different heights, would seem odd. Your thoughts? At 10:50 AM 9/1/2004, you wrote: > I like your idea with the two end stacks having caps like photo #27. Greetings again XXXXXXX, I am glad you like my ideas and the progress. Here is the latest pictures of the progress. I decided to go with 16.5" stacks on the side ones instead of only 13.75", and a 22.5" stack on the center one to be 6" higher. The center stack is already 3' tall. It is likely to be a good 4' tall when I am done. The #13 picture shows the upper ornamentation laying face down. Boy, was that tricky. I held it in place while Tia drilled the first holes for the rivets to hold that upper ring together. In #15 it shows the back side of these stacks, and the single seam on the 8 sided stacks. There is 1.5" that overlaps. It has 3/4" on each side of the bend. They seem to be turning out well. I even amaze myself some times. Sorry I had to make you worry with all the delays, after paying out all that money. At least now you can see your money was not misplaced, and this is going to become a reality.

Many Blessings, XXXXXXX
Day four & five (9-2+3-04)
Here is what we have done after a week of full time work on these stacks. We decided to go with 16.5" tall 8 sided stacks for the two outer units, instead of only 13.75" as would be proportionate to the clay version. This way it looks a little less stocky. We went with a 22.5" stack on the center unit, to be 6" higher than the other two. The center stack is 3' tall now. It is likely to be a good 4' tall when we are done. The right chimney pot in the picture shows the upper ornamentation installed. They still have a clear plastic film over most of the copper shown. I will peal it off after installation. They seem to be turning out well. I even amaze myself some times with what I am able to design and create.
Day 6 (9-7-04)

Here is what we got done on Monday (9-6-04). The top cage made to top the short stacks. The screen acts as a spark arrest and also will keep pests out when not in use. I decided that these 8 diamond vents would look best, and still have a good twice the vent surface as the size of the stack it's self.

Day seven (9-8-04)
	Here is the vent cage being cut and bent into shape.
Here it is being folded into shape.

Day eight (9-9-04)



Here is the set of 3 stacks side be side again with the 12/12 pitch 8 sided caps over the vent cages on the pair of outer smoke stacks. The caps are 13.25" wide with safety hems bent on the bottom edge for strength and so there are no sharp edges on it. There is 16 copper rivets holding each cap in place. These are now 3' 6.5" tall. We still have to make the small rings for the taller chimney stack and the Cathedral style cage vent and cap. This center cap/vent is not complete yet. There is 6 separate pieces just loosely set in place to take this photo. It is now 4' 7" tall, but when it is riveted down tight, it will be about 1/2" shorter. They are looking a lot like chess pieces. Maybe 2 Bishops and one King? The center one looked more like a Rook before we set the vent/cap on it. At $2,000 for these 3 chess pieces, this would make for a rather expensive set. <LOL> Even at $2,000 for this set; I had given XXXXXXX a very good deal, considering all the design and work we have put into this project. We were so jazzed about this project and using these photos for the web site, we were willing to put the extra time and effort into this project, without charging her more for these design enhancements.

Here is their house with the new copper gutters about to be installed around the wrap around deck that XXXX had painstakingly rebuilt.
Here are these chimney pots a few years later: I happen to stop by a few years later to see how they had tarnished and managed to get these photos from up on the roof with the owners permission. I would normally not have bothered them with this, but I had noticed that I had left some of the clear plastic film on the copper in a few spots. Can you tell where? It was not easy to remove after being out under the sun for the last 2 years.
