Building your own brick smoker is a relatively easy project with the proper tools and materials. Smoking your meat and vegetables with a brick smoker can enhance the flavour of your food year round. You can make homemade smokers out of bricks or breeze blocks; bricks have better heat retention qualities, but breeze blocks are less expensive. When constructing your homemade brick smoker, make sure to build on level ground, or before making the smoker, construct a concrete slab.
Use 20 by 20 by 40 cm (8 by 8 by 16 inch) breeze blocks to create the base row for the smoking chamber. Make parallel rows by using two breeze blocks set end to end for each row; leave the front open, but close the back with one breeze block perpendicular to the rows.
Set a metal lintel across the front sidewalls that it rests above them, as this will help support the subsequent rows of bricks. Build up the side, front and back rows with bricks until there are five rows. Each row should have a staggered pattern of brick placement.
Use a sturdy piece of cardboard or a cut of plywood to cover the top of the smoker. Cut the piece to 80 by 80 cm (32 by 32 inches) to completely cover the top.
Construct the fire pit by placing two more bricks end to end, extending from each of the bottom most rows in the front of the smoker. Place three perpendicular bricks above this extension so that once a fire is built, the smoke will funnel through the fire pit to the smoke chamber.
Insert screens or sticks for holding meat during the smoking process by pushing in opposing rows and allowing them to straddle the screen or sticks. Use spacers if you prefer to be able to insert the screens without having to push in the bricks.
If you would like the smoker to be more permanent, you can mortar the cinder blocks with cement. It is a good idea to try it out a few times first, though, to make sure it is working the way you want it to before cementing it in place.
