A core is used when …
A core is used when the middle of the casting needs to be hollow or has a cavity of some kind. In his video one is used to make the cylindrical objec into tube shape. Without the core it would be a solid cylinder. it is supported at the ends only and the metal flows around it.

I don’t see anyone on Youtube discussing a solid pattern, which can’t be cut in half. Do you pound it into the drag, or try and build a bottom board with matching indentations or what???

As my engine will run on butane gas the tank does not need to hold fuel so I have cast the ends seperatly to make it easier.
The pattern has “core prints” added to the requred shape and this leaves a shape in the sand to support the core.
