Part 2. Preparing the reinforcing mesh
Steps 2.1 to 2.3 Cutting, shaping and tying the mesh
The reinforcing used in this project is *welded wire mesh. It is a grid of 5/32″ (4mm) thick wire with spacings at 6″ (150mm).
This reinforcing mesh and method is not the only way. Other material and methods can be applied. See the note at the bottom of this page.
Step 2.1 Cutting the mesh
Cut the mesh to the sizes given in fig.1. Cut one A piece and two B pieces.
The B pieces will have to be trimmed, bent, and shaped to suit.
*Note: Home-mixed A mixture of sand, gravel, water and cement which hardens to a stone like condition when dry. is not always as strong as it could be, so reinforcing steel or mesh is necessary. The mesh and method used in this project is but one way of adding adequate reinforcing. You can even make up your own grid using the same size or a thicker rod, and join the intersections with tie wire. The most important point is that the reinforcing covers the area of the seat and is also tied to other reinforcing that bends into the leg area.
