Apologies for tone. |

Just an additional point of information -- sprues and risers would have to be pinned loose pieces in the above plate I show because they would probably only be useful in the cope. The plate is rammed up in both cope and drag. You could do the gates to one side only, but they will then appear in the cope on one casting and in the drag for the other, thought that isn't necessarily a problem. Or it could be a split pattern like the main pattern -- you'd have to make two matching pieces for each, and they would go to each side. |

Here is a plate pattern I made VERY many years ago. Initially casting aluminium, but I have successfully cast brass and iron from the same pattern. Designed for a custom made wooden flask, and done in CO2 / sodium silicate sand. I made up several at a time, sandwiched them between plywood boards, and clamped them up with studding. Obviously cast in a vertical orientation. It makes a copy of a Victorian 'Khasi Bracket' of the sort used to support high level toilet cisterns, but now used for shelves and all sorts. I've still got one supporting a large brass bell at my front door. |
