Step-by-step procedure

1.     Measure and Cut Steel Bars

o   Measure and cut mild steel square bars (5 mm thick, 20 mm wide) into the following lengths: 300 mm, 150 mm, and 140 mm.

o   Use a measuring tape, marker, and angle grinder or cutting machine.

2.     Weld the Base Frame

o   Weld four 150 mm square bars to form a square base.

o   Use a set square and clamps to ensure all corners are exactly 90°.

o   Use an arc welding machine, set square, and clamps.

3.     Make the Top Frame and Support Bars

o   Repeat the previous process to make a top square frame using four bars.

o   Weld two horizontal and two vertical bars inside this frame to create support for the pot.

o   Use a welding machine, measuring tape, and square.

4.     Attach the Legs

o   Weld four leg bars (each 300 mm) vertically at the corners of the base frame.

o   Use magnetic clamps or jigs to keep the bars upright and stable while welding.

o   Use a welding machine and magnetic clamps or jigs.

5.     Assemble the Frame

o   Place and weld the completed top frame onto the tops of the four leg bars.

o   Ensure the frame is parallel to the base and that all legs are properly aligned.

o   Use a welding machine, clamps, and measuring scale.

6.     Finishing Work

o   Grind and smooth all the welds to remove spatter or burrs.

o   Apply anti-rust primer followed by black enamel paint for durability and an improved finish.

o   Use an angle grinder and sandpaper for smoothing.
