I created a master of a broken stone wall. It was created from aquarium stones on a wooden base. I then made a mold of the master. The master was destroyed in the removal process. Here are a few photos of the cast wall.
This is the production line at present.
This is the mold.
Here I have combined the wall section with the wooden fences for reference.
I am now waiting for the gate section and 2 different straight section molds to set. Will keep you posted.
