How can I create a mold for a large concrete pot ( greater than 1.5 by 1.5 metres) ?
I wanted to have series of pots next to a deck . Rather than just square,I wanted to have something like half a sphere drawn up; maybe a better way to describe it is a cone with the point cut off and inverted.
I could make an internal mold with heaped wet sand , but how can I mold the walls for consistent thickness, reinforcerd with wire and asmooth exterior
The problem is to create a pourable mold in an interesting shape.
