With the interior done I focused on the outside. First the insulation. R 7.5 Pink foam board 1 1/2 thick.
I caulked around the smoke stacks before insulating. I don’t want any leaks.
Then the roof went on and more caulk.
Next was the fascia and some paint.
Then some tar paper.
Then the metal roof and drip edge and some white silicone caulk over the aluminum nail heads to prevent any leaks.
Normally drip edge goes on before the tar paper and is covered by asphalt shingles that cover the nails holding the drip edge. The thin metal is not as robust as shingles so I used the drip edge to hold the thin roof metal down and to cover all the nails holding it in place. I put a large bead of silicone under each piece of drip edge before nailing it in place.
Since I don’t want rain and snow getting into the smoke stacks and since I cant find any caps for 3 inch ducting I made some from galvanized sheet.
The rolled it and riveted the joint.
Since I also can't find inline butterfly dampers for 3 inch ducting, I made my own from brass threaded rod and stainless hardware (no rust). It was pretty much a huge pain in the butt but it worked out ok.
I started cutting the pieces of siding and painting the exterior corner trim. I hope to get that installed tomorrow so I can make the doors.
And I spent some time working on the upper door. The face of the door will be two layers. 1. is half inch plywood and 2. is the same T-111 siding I've been using. It will also be insulated framed with 1 1/2 x 1 1/2 lumber.
Then another layer of plywood to support the metal lining.
I start the aluminum at the bottom and overlap all the joints like shingles on a roof so no moisture can get to the wood.
Then the sides.
Then the face. (all metal is held in place with aluminum nails)
The top piece is the same as the bottom except it laps over all the other pieces.
With the top door completed, I began the bottom door. This is where I will load wood chips and adjust the heat without opening the big door and losing all the heat I built up. In order to have proper venting and air flow to the smoke stacks, I need a fresh air intake. I need to prevent unwanted intruders from entering the smoker (mice, wasps, etc) so I folded over the edges of metal window screen material and screwed to the inside face of the door and I added a set of hinges.
The front of the door as a floor register vent that I can open and close to adjust the air flow. The white metal around the outside edge of the door is aluminum angle use for suspended ceilings. It was just the right size and color and material for this job. It covers the cut edge of the siding and the edge of the aluminum I wrapped the door with.
Both doors get a weather-strip seal all around.
To make moving the smoker easier, I added steel casters. I don’t want rubber casters that will take a flat spot after sitting plus the hard rubber caster will eventually rot from exposure to the outside.
Then it was time to hang the doors.
Just for grins (and because I would not be able to see myself) I set the timer on the camera and placed it inside the smoker to see how the door fits and looks from the inside. All seems well.
Now I will add a side table, door latches and build the cold smoking adaptor box. This project seems to be never ending.
I added over-center catches to draw the door tight against the seal. The upper door gets two and the lower door gets one.
Then drilled a hole for a heat probe. I will have one in the door and another digital remote version.
Then I fired it up using two electric hot plates rated for 1000 watts each. I put a rack in to support the probe.
The temp in my garage was 55F. It took over an hour to heat the inside to over 200F.
Then I took the legs off my propane turkey cooker and placed it inside to see how propane would fair.
And placed a heavy cast iron griddle used on Scout outings over the flame to act as a dissipater.
In two minutes I was over 230F and I kept having to turn the burner down till it was just a faint flicker of a flame. This is no longer an electric smoker project. It is now a propane smoker project. This burner is rated at 45,000 BTU. I will shop for a lower rated burner and make accommodations for the hose to leave the smoker.
After learning of a product called the “A-maze-n-smoker “ I have also scrapped the idea of an external smoke box and flexible dryer vent hose to deliver smoke for cold smoking things like cheese. After reading about the product, I made a few of my own. It’s a perforated metal box that is 6 x 6 inches with a maze if metal strips that is filled with sawdust and let to smolder in the smoke house without generating heat. It’s a freaking awesome thing.
Here are the parts I cut out before assembly. I used aluminum.
Then after cutting and bending.
Then riveted together.
The rivets act as legs to space it away from whatever it sits on so air can flow under it.
Then I filled it with sawdust and lit each end through the hole I cut. The store bought version claims it will smoke for 8 hours if lit on only one end. I lit mine on both ends just to see how it would work. It produced a lot of smoke. I lit it at 5:30 pm.
Here it is at 6:30
When it was burned out, I knocked it upside down and rinsed it with water.
I’m really impressed by this thing. He sells it for $32. I will make a few more for myself. If you’re in the market for a very cool cold smoking, smoke generator, I would highly recommend checking his product out at.
Im adding a side table to the smoker because when I carry racks of things to smoke, out to smoker, I need my hands free to open the door. The table will make it easier. I want the table removable without tools so I can store it inside the smoker when I’m not using it. Because I’m working on the outside of the smoker and it’s a nice day, I bought several varieties of local made cheese to cold smoke (it was 55 degrees this afternoon)
But first I needed some sawdust. I cut down a sugar maple 2 years ago so I passed a piece of it through my table saw until I had enough sawdust to smoke the cheese.
Then filled the smoke pan.
I took a big pan of ice out to the smoker about an hour before I wanted to use it. Since this is essentially a big, insulated cooler, the ice dropped the temp inside from 55 to 44. Then I cut the cheese. I’m smoking Cheddar, Swiss, Pepper Jack, String cheese and Cheese curds.
Then into the smoker with the sawdust pan.
While working on the side table I peeked at the one hour mark. I can't believe how much smoke that little pan makes. That thing rocks!
As I said, I want to remove the table without tools so I used a Dremmel tool to key-hole-slot the tops of all 4 holes.
Then screwed in large screws but left them sticking out a little more than the thickness of the bracket.
But enough about the table, its two hours later and the cheese is done. I emptied the sawdust pan to keep from choking and let the smoke clear.
The almost finished product.
I bagged it all separately and then placed all the bags in another gallon sized bag and put it in the fridge where it will sit for two weeks and we will enjoy when we have guests at Easter. Why? Everything I have read about smoking cheese says that if you try to eat the cheese right out of the smoker, it will taste like licking the bottom of an ash tray (I can only imagine what that would taste like) so the cheese has to mellow and absorb the smoke before it can be enjoyed……………………………… But being impatient, I sampled one of the cheese curds. Yup, ash tray, all the way. It was awful. If I had not read up on the subject, I would have thrown the whole lot in the trash, thinking I had done something wrong. It pays to study.
Back to working on the side table. I want a table that is easy to clean and removable without tools. I made a wooden frame that sits on the two shelf brackets and then covered it with plywood. Then I wraped it in aluminum. This is a heavier gauge than I used inside the smoker so it was a bit harder to bend.
The sheetmetal edge was a bit too sharp for my tastes so I put an edge of aluminum strip that is an 1/8 x 1 1/2. I held it in place with stainless steel screws since it will be exposed to salt and the elements.
I was able to find a propane burner that I think will work well for this project. It has 3 separate burner rings with adjustable settings. I found it at Northern tool for $40. I hope to have it in a few days.
When I was going to use electric heat, I was content with the aluminum over wood smoke/heat chamber. Now that I will have open flame, (and the potential for flare ups) I have decided to line the lower chamber with ceramic tile. The biggest consideration is the temperature extremes. This smoker could be -10F one day and with me using it, 225F the next day. Because of this, I can’t line the chamber with ceramic using conventional methods. I have to allow for a large amount of thermal expansion. To account for this, I will loosely hold the tiles in place with a roofing product that is used for soffit and fascia. The Home Depot carries it under the name of “J” channel. Its made of aluminum. I will screw it to the side walls of the smoker.
I used 12 inch by 12 inch tiles (.57 cents each). The tiles on the floor will not be in “j” channel and will be allowed to float.
Completed. This might be overkill but I think its cheap insurance against burning this thing to the ground.
I was going to use 16 inch tile so I bought a sample (.77 cents each) but ended up using the 12 inch. I will place the large 16 inch directly under the burner.
Lining the door with ceramic proved to be a bigger challenge due to the air vent. I used an abrasive cut-off blade in my 7 inch circular saw to cut the openings.
They will also be held in place with “J” channel.
The ceramic lined bottom chamber.
Once the burner arrives and I figure out where to run the propane line, I will have to cut a hole in a tile and the side of the smoker for the line to exit the smoker.
While I’m waiting, I painted a sign. My Son named my first smoker “Old Smokey” and insisted I paint a crescent moon on the door. I can think of no reason to break with tradition so this smoke will be dubbed “Old Smokey II” and also bear the crescent moon. While taking pictures, a neighbor stopped over to ask how I got a permit to put an outhouse on my property? After a bit of explaining, he understood.
Here is what “Old Smokey II” looks like so far.
Now I'm just waiting on the UPS delivery man and the burner.
The propane burner arrived. It’s a heavy and durable piece of equipment. The only mod I made was cutting 2 inches off of the legs to lower it. Then I went and got some iron pipe and fitting so I don’t have to have any rubber regulator line inside the heat of the smoker.
Then a notch in a tile and a hole drilled through the side wall.
I’ve got gas.
I lit the smallest burner ring and let it burn to see how hot I could get it at its max setting. I brought the inside temp to 270F which is way hotter that anything I will be needing but I wanted to test out the door seal gasket and see if the whole thing would take the heat. Each burner is adjustable so I will be able to tweak the heat as I like and have extra to spare for when it below zero outside.
Then I did a hot smoke in the new smoker. My oldest was home from college and wanted ribs. I used the 3-2-1 method. 3 hours over hickory smoke between 230 and 250F with Famous Dave’s rib rub. 2 hours wrapped in foil with apple juice at the same temp and then 1 hour smoked unwrapped with some Famous Dave’s BBQ sauce.
This was the first propane smoking using chunks of Hickory and cast iron. They lasted a good long time and produced a great smelling smoke.
They came out falling off the bone. Next weekend it will be whole chickens, ribs and sausage for out of town guests visiting for Easter.
Things quieted down enough and I have a free weekend so I ordered a 60 pound case of boneless pork picnic shoulders. (What the hell happened to meat prices?? What I used to buy at .88 cents a pound was $1.60 a pound >:( ) anyway, I took 30 pounds of venison out of the freezer so I could make a 60 pound batch of breakfast sausage. Then I cut up a few of the pork shoulders into small pieces for grinding.
Then ground them together.
Our family likes the Hi Mountain brand of breakfast sausage seasoning so I got a few boxes. I mixed it with a quart of cold water and 4 tablespoons of crushed red pepper flakes for some heat.
Then I grind it again through a smaller plate.
Then I convert the grinder into a stuffer and bulk pack it.
In order to continue pork-a-palooza, I saved 15 pounds of butts for the smoker tomorrow. It will spend the day in the new smoker.
Since the trees have already budded out and I know some of the apple trees at the back of ourproperty need trimming, I killed two birds with one stone.
There is a soon-to-be Bacon palooza pictorial coming at some point and I plan to use apple wood so it will be ready when the time comes. This is more than enough for today.
After 8 hours in the smoker, the pork butts were ready for pulling.
Pulling pork is a perpetual pain in the posterior and something I wanted to speed up so I went to Ace hardware and bought a cast iron floor drain (like you probably have in your basement floor) a few 3/8 bolts and nuts and a 12 inch long bolt to make the perfect pork puller.
I invited the folks from Youtube over to have some pork and to video the perfect pork puller in action. The pork is only minutes out of the smoker and very hot. You will notice the steam. The Youtube folks were nice and all but they sure can eat. Click below to watch the video.
WOW! - Beautiful work! Is this strictly for cold smoking or do you plan to slow cook in this as well? I once considered a pair of 100W light bulbs to heat up one of these - then from there maybe an attic thermocouple to regulate the temp with a relay - IF you can find a thermocouple with the correct temp range. Just thinking into my keyboard....
And on the eighth day God created barbecue …. because he DOES love us and he wants us to be happy.
