Marking: Precisely scribe the trapezoidal shapes that will form the pyramid onto the sheet metal. Double-check all measurements. Use a white marker, chalk, or a scribe for marking. Obtain the dimensions from the project plan.
Cutting the Sheet Metal: Place the sheet metal on the plasma cutter grid. Set the appropriate plasma amperage and cut the pieces. Cut the pieces slightly larger than the final dimension to allow for later adjustment by grinding. Turn on the extraction system before cutting. To achieve the cleanest cut possible, use a straightedge and magnets to hold it in place. A steel angle profile has proven to be an excellent aid for straight cuts. Always wear leather gloves and proper eye protection!
Edge Preparation: Remove slag with a metalworking chisel, deburr the edges, and check the dimensions. Correct any deviations greater than 2–3 mm by grinding. Perform a dry assembly of the pieces using magnets to check the fit.
Assembling the Pyramid: Position the three trapezoids using magnets and tack weld them. Leave a small gap between the plates for better weld penetration. Then, complete all welds fully.
Making the Base: Place the welded pyramid onto the sheet metal and trace its outline. Cut out the piece, deburr the edges, and drill several holes for air supply and water drainage. Then, weld it to the bottom edge of the pyramid.
Grinding: Grind the weld surfaces and the edges of the pyramid to prepare them for leg attachment.
Making the Legs: From the leftover trapezoid cuts, select the three most aesthetically pleasing triangular pieces. Grind and clean them of slag.
Leg Assembly: Tack weld the legs to the base of the pyramid, check the alignment, and correct if necessary. Then, weld them securely. Weld small metal washers to the bottom side of the legs.
