The brickwork requires no tools other than those normally used in building: shovel, trowel, plumbline and square.
Standard mild steel sections have to be cut, either at 90° or 45°, using either a powered or hand operated saw.
Mild steel plates can be cut to shape using an angle-cutter grinder or by hand using a hammer and chisel.
The chimney is best made from mild steel tube, but if this cannot be obtained mild steel plate must be rolled in sections and the sections welded together to form the chimney. This process is best carried out using a rolling machine, but in extreme necessity it can be done manually by rolling the plate sections over a wooden former.
The incinerators described here have been designed to be manufactured on site using only the most commonly available tools.
