To make the tower structures I used castling. Each bit of castling had e length of 5mm and a height of 4mm, I was using 4mm thick ply wood. I used a grid of 1mm by 1mm on Corel Draw and dew with the poly line tool.
When cutting the wooden cogs, rather than mess around trying to get the shaft size right in the program, I had the circle engraved rather than cut out then drilled the 6mm hole using the circle as a guide.
The Ceramic shells are buried up to the cup in sand and the bronze is poured. 3 people are involved in pouring 2 people, the pourer and another the bronze to the sand pit, the pourer pours the bronze while the other holds the other end of the bar the bronze is held on and keeps it level, the third person guides the pourer.
Though I would like to be able to use bronze casting in my field project, it takes too land and there isn’t enough time left on this project. I defiantly want to do this proses again and explore making larger more experimental casts.
