Introduction: Smoking Bad (Ugly Drum Smoker)

Picture of Smoking Bad (Ugly Drum Smoker)

I've been looking to build a smoker for a while now and there are plenty of great resources out there (especially in the states). I was debating whether to write this up as an Instructable at all as there are other people making great ones on this site already. Such as this guy:

https://www.instructables.com/id/Build-Your-Own-Ugl...

and this guy...

https://www.instructables.com/id/Ultimate-Ugly-Drum...

and some amazing resources on :

http://www.bbq-brethren.com/forum/

This Instructable draws **heavily** on the ideas of the other builds and, in my opinion brings the best ideas together into one simple build.

The main reason I'm writing this up is that ALL THE OTHER BUILDS ARE IN THE US! We don't have cool shops like Home Depot or Harbor Freight over here in the UK so I thought I could contribute with a build that uses bits from the stuff we have available over here.

Oh and the theme? : Jessie and Heisenberg get the smoker made out of an old Methylamine barrel lit in the middle of the desert. After 12 hours of hard cooking in the R.V they can tuck into a beautiful succulent piece of smoked brisket before packing up and driving home.

Hope you enjoy. Wear your safety goggles!

Step 1: Stuff You'll Need

Picture of Stuff You'll Need

OK so here's what you need for the build:

A Barrel/drum

A 205 Litre/45 Gallon Steel Drum/Barrel like this one. Note, i think you probably don't want one that had nasty chemicals or oil in it (though some people say its ok as long as you give it a hot burn-out before using it). I chose one that had apple juice in it in its previous life.

Castors (wheels) like these: http://www.ebay.co.uk/itm/Pair-of-Kart-Industrial...

28mm bore copper pipe & fittings

Steel

Hardware

Other:

Tools:

  • Hacksaw
  • Electric jigsaw (optional for table)
  • Drill
  • 28 or 29mm hole saw,
  • tin snips
  • Welder

Step 2: Prepare the Barrel

Picture of Prepare the Barrel

This is probably the least rewarding/ hardest work part of this build. All the paint must go! If you are lucky enough to find an unpainted barrel you will save a load of time.

My tip for this is to use some hardcore paint stripper containing Dichloromethane (I think in the US they call it aviation stripper or something like that). Hard to get but worth it if you can find it. PLEASE USE IN WELL VENTILATED AREA WITH PROTECTIVE GEAR PEOPLE!! The stuff is really scary. Even the tiniest bit on your skin starts burning immediately.

Apply, wait for a bit for the paint to bubble, scrape, repeat (for ever).

Have patience, it will be worth it.

  • Once all the old paint has been scraped off, give it a good wash and dry.
  • Get some 600 or 800 grade sandpaper and prepare the surface for paint (not really sure if that helped as the finish was still rubbish)
  • Spray with the engine enamel paint

Step 3: Fit the Shelves

Picture of Fit the Shelves
  1. Measure the circumference of the oil barrel and divide into quarters. I used a bit of string to do this. Im sure there are others.
  2. On each quarter mark, measure 2cm from the rim and mark with a pen.
  3. Centre punch on the mark and drill a 3mm hole
  4. Bolt the top hole of a shelf rail losely and let it swing vertical. Mark out the remaining holes with a pen then mark and drill.
  5. Repeat for the other 3 rails.
  6. DONE

The shelves will let you adjust the height of everything later on (neat idea stolen from one of the other Instructables).

At this point its probably worth mounting the thermometers too. You want them at the bottom and the top of the area you'll mainly be cooking your food. Make sure you are (1) far enough away from the fire box (2) you leave yourself plenty of room to place the shelf where you can fit in some immense pork shoulders or brontosaurus ribs. Thats the name of the game after all.

Step 4: Build the Base (optional)

Picture of Build the Base (optional)

This next step is optional as you don't really need the base. If you can, if recommend doing it as (1) its really practical being able to move the smoker around easily even when hot and (2) it will prevent it rusting if you leave it out every now and again.

  1. Cut 1 length of the 30x30 box section to 67cm
  2. Cut 2 pieces of the same box section to 32cm
  3. Use a right-angle welding clamp and tack the pieces into place as shown and ensure still aligned with a set-square
  4. Weld-up both sides. I think I used about 70amps here but its not critical. Just use the recommended settings for mild steel.
  5. Drill 10mm holes at 1cm from each end of the base (for the casters).
  6. Drill a 10mm hole directly in the centre.
  7. Spray
  8. Bolt on the wheels

DONE

Step 5: Make the Air Valves

Picture of Make the Air Valves

This step is really easy apart from removing the lip on the inside of the tank connector. We want to do this to get the air intake pipe to go underneath the fire box for a more even burn. Not sure of how much difference this really makes but worth it if you can.

I used a lathe to remove the lip. You can probably get away with a rotary tool like a Dremel too but be careful not to butcher the fit further up the fitting where the airtight seal is made with the brass olive.

Anyways, heres how I did it:

  1. take apart the tank connector.
  2. Chuck the large bit in the lathe and skim off the lip with a boring bar. I used an indexable carbide tipped one but as its brass HSS would be just fine too.
  3. Cut the copper pip in half to 2x 300mm lengths
  4. Cut a 29mm hole in the side of the barrel
  5. Assemble Ball Valve, Tank connector and valve on the barrel as shown and tighten up with some big spanners.

DONE

Step 6: Make the Fire Box

Picture of Make the Fire Box

This is probably the trickiest step and I'm not sure if there isn't some easier way to do it. Its my original design and having done 5 successful 12hr+ smokes now so I can say it works perfectly! If you don't want to weld, take a look at some of the builds that use 'expanded metal' from Wickes etc. This stuff is easy to bend and you can just join it by twisting wire together too. I was also thinking if you couldn't just use some sort of bucket BBQ in there too.

Anyway, to make my firebox this is what I did:

  1. take the perforated sheet and mark out 5 x 250x250mm squares as shown.
  2. Take the tin snips and cut round the outline. WEAR GLOVES or your hands will end up looking like you've had a fight with a cat
  3. Bend the sheet into a cube shape by clamping it down onto a surface with a bit of wood and a G-clamp. A metal brake would get you a cleaner bend here (as you can see in the finished product).

The base:

  1. Cut 4 pieces of the 30x30 angle bar to 27cm
  2. Cur the mitre to 30mm as shown in the photo. I just did that with a hacksaw
  3. Tack and weld
  4. Cut 4x 70mm lengths of the 15mm pipe and weld on in the corners
  5. Place the cage from the previous step into the base and spot weld into place as necessary to make it rigid and secured in place.
  6. Take the chain and bolt onto the side as shown.

DONE

Step 7: Make the Beer Table (optional)

Picture of Make the Beer Table (optional)

This step is optional and actually i didn't have it the first time I used the smoker. Immediately i wished there was somewhere to place the beer/utensils/thermometer etc so made this.

  1. Cut a bit of the plywood to 40x30cm
  2. Take the lid of the barrel and mark round it on the wood. This is not 100% ideal as the rim is a bit bigger than the body of the barrel but its close enough.
  3. Cut out the semicircle with the Jigsaw and sand the edges etc

TOTALLY OPTIONAL:

  1. Deck out with some sweet graphics. I used a CNC router to engrave the shapes as a 1mm deep pocket tool path using a 3mm carbide 2-flute end mill.
  2. Once the pocket is engraved, paint it with black outdoor gloss paint (don't worry too much about being precise at the edges).
  3. Once dry, sand over the top and it will look crisp at the edges with the overpaint removed.
  4. once done, varnish over the top with some outdoor varnish.

Mount the table on the barrel.

  1. Choose a height near the rim (e.g. 10cm down from the top) and punch+drill a 6mm hole.
  2. Screw through the hole into a pre-drilled pilot hole in the table.
  3. Level the table (measure the same height from the top some way further around) and punch + drill + screw two more screws. This should hold the table up in position while you make the support but i wouldn't put any weight on it yet.
  4. The the 20mm flat bar and bend a support as shown. Sorry i can't provide any angles etc as this was done totally by trial and error.
  5. Once the support is on, the table IS RIGID. really solid.

DONE

Step 8: Finishing Touches

Picture of Finishing Touches
  • Decorate the barrel. Here I used the Breaking Bad Golden Moth company Methylamine barrel logo (included in the accompanying files for this instructable)
  • Printed the logo out on A3 paper
  • Glued the paper onto some Frisket low tack masking film and cut around with a scalpel
  • Stuck the film onto the barrel and sprayed.

The result wasn't really that great at all. Main problem is that the barrel is round and the film flat. I had real trouble getting it to stick flat (actually it was impossible). I'd say there has to be a better way of doing this (maybe someone else has an instructable out there).

last thing to do is drill some holes in the top. I think these were 20mm. You really don't want more than this.

Step 9: Conclusion

This was a very fun build and works really, really well. The temperature stays quite steady when set and the coal easily lasts for 14hrs when using briquets (lump wood charcoal less).

I have cooked meat 10kg at a time and fed 40+ people at a party. The smoker is a good conversation piece and nice place to gather round a drink beers.

What I'd do differently next time:

  • As I mentioned, the fire box while it works really well, was expensive in terms of material and time to make. Id probably go with some sort of expanded metal thing/a modded cheap BBQ from the supermarket.
  • The paint finish isn't great + the enamel was quite expensive. For the final cost of the rattle cans i probably could have had the thing professionally powder-coated and looking much sharper.

My next mod for this was an electronic temperature controller using a throttle body from a car to adjust the air flow. I will write this up in its own instructable.

Thanks for reading,

P

I am sorry, what is this thing used for?

WayneH82 (author)RobertZ72017-01-05

By the lord thunderin Jeeze Boy!!

It is used for the winter days/nights when the weather shes a freezing outside! All one needs to do is jump aboard like on a horse, then jes sit on yer haunches for a short while. It can get ve-ery co-o-l-d !!! and the next bestest thing to hang yer hat on is one of these here they callit bunnwarmer for them cold evenings, well you take care and let me know what yer next question is all about. Have yourself a toasty evening RobertZ7..............

sconnors (author)2017-01-05

Nice ideas here!

After your description of the labor, I would probably build a big fire in the drum and wire brush the charred paint off the outside.

jimmijames64 (author)2017-01-05

Nice job, for the firebox you might be able to use the charcoal pan out of a Brinkman smoker its round and smaller the the drum. OR something like image which is a stainless steel grill basket.

pat_pending made it! (author)jimmijames642017-01-05

Hi Jimmi, Thats a great Idea. Unfortunately no way you can buy these in the UK! So frustrating. I was thinking maybe a modded version of something like this would do the trick nicely but they might be a bit small.

JerryT41 (author)2017-01-05

I've built one....but not even close to as nice as yours!!!! I use an old old cheap grill for a fire box. Almost anything that holds the wood/charcoal will work, for a while

pat_pending (author)JerryT412017-01-05

Hi Jerry, thanks for commenting. I think a cheap grill is definitely the way forward and would save the hassle/ cost of building my fire box. It does work great though!

pat_pending (author)2016-12-25

Hi Fred, good luck, hope the build goes well. Another Instructable on the way. P

fred3655 (author)2016-12-24

I love the idea about using an automobile throttle body to regulate the temperature. That alone deserves another instructible!

I can't wait to build mine. I think it would be easier to find a metal bowl of some sort, cut a hole in the bottom and lay a piece of mesh in there for the fire box. Cheers from across the pond.

pat_pending (author)2016-12-24

Hi calculator - thanks for commenting. The black paint is super heat resistant while the original green paint was not. The green paint would have started smoking and burning off immediately. P

pat_pending (author)2016-12-24

Hi nramirez, thanks for commenting. You would be absolutely right regarding the differing metals. This is all plain old mild steel so no problem there. The expanded metal (the mesh you put in the wall before plastering) is what i was referring to. Thats galvanised too so you definitely don't want to be welding it. P

nramirez10 (author)2016-12-24

looks awesome! but im curious aboust your fire box, the expanded metal you used looks like stainless steel and the angle bar and chain you used looks like carbon steel if so eventuallythe carbon steel will make the stainless steel rust and fall apart it might take a while but it will happen. however, if it isnt stainless steel then you shouldnt have a problem with it. i work for a mechanical contracting company and we deal with all kinds of metal so its something that came to mind when i saw the difference in the way the metal looks

calculator01 (author)2016-12-24

is stripping the original paint really necessary or was this done only to repaint? basically, could you have made a green smoker?
