How to build a smudge pot

Smudge pots are heaters. They were used to heat orchards when fruit-bearing flowers were threatened by frost. They work by heating the air and creating a protective smoke layer over the trees. They were deemed environmentally hazardous and their use was prohibited in the late 1970s. You can build a retroversion of the smudge pot using lantern or citronella oil that is environmentally safer. They are also known as "choofa" pipes because of the sound they make when burning.

Unscrew and remove the 7.5 cm (3 inch) cap from a water-based paint can. Turn it on its side. Place a garden hose inside and spray it clean of paint. Turn it upside down and let it drain.

Place the stovepipe on top the can, to one side of the 7.5 cm (3 inch) lid. Trace around the pipe. Using the reciprocating saw, cut out the circle. Force the crimped end of the stove pipe into the hole. Penetrate about 15 cm (6 inches).

Insert the bell flange over the top of the pipe. Slide it down to the top of the can. It should cover part of the 7.5 cm (3 inch) lid.

Drill about 50 or 60 holes into the pipe with the 3 mm (1/8-inch) bit and cordless drill in random order around the pipe's diameter just above the bell flange.
