  1. Assemble the Body:
  • Weld the sides, back, and bottom together, ensuring all joints are airtight.
  • Attach the top plate securely.
  1. Install Fire Bricks:
  • Line the interior with fire bricks, ensuring they fit snugly.
  • This will enhance heat retention and protect the metal structure.
  1. Create the Door:
  • Cut a section out of the front for the door.
  • Attach hinges and install a handle for easy opening.
  1. Add Air Control:
  • Incorporate an adjustable vent at the bottom or side of the stove.
  • This allows you to control the combustion rate.
  1. Install the Stove Pipe:
  • Attach the stove pipe to the top or back of the stove.
  • Ensure it is securely fitted and leads to a proper chimney or flue.

Testing and Safety Checks

Before using the stove, perform the following safety checks:

  • Leak Test: Check for air leaks around joints and seams.
  • Stability Check: Ensure the stove is stable and securely positioned.
