This update is about the making of one of the elements of the sculpture, the right side torso. It is one of the abstract elements, so just a simple flat slab of 20 mm thickness. Here I have shown it in pale gold:
It has four 30 mm stainless steel connector washers embedded halfway in the thickness of the slab.
This photo shows the sacrificial mould on the left, with the finished cast on the right. The bottom of the mould is paper with the profile printed on it. The walls are 20 mm wide strips of bent 3 mm foam board, glued to the base with white PVA glue. The wooden blocks are glued around the perimeter to the paper base to support the walls when the concrete is poured. As a release agent, the mould bottom and walls are given three coats of gloss varnish, to which cured concrete does not stick at all. To prevent buckling, the base paper is mounted on thick PVC sheet (not shown in the photo) with Scotch Spray Mount adhesive spray.
The photo also shows one of the PVC electrical conduit connectors, held in place with 10 mm alignment bolts in the support sheet, to make the holes during the pouring. The stainless washers embedded in the concrete can be seen in the holes.
My previous offer of help and advice still stands, if anyone else here would like to tackle a similar project.
