Getting ready to pour some test molds. The first contraption only varies the thickness of the modules in section which is not enough variation.
So through many trials and errors Ive developed an adjustable/flexible mold that introduces six points of controlled variation to allow section thickness to conform to the path of water flowing down and thouroughout the waterfall wall. This mold is made up of hinges the unfold the cast out of the mold to eliminate issues.
On to some test pours.
