myfordboy makes this look so easy in these videos.Then when you start to actually want to do this yourself you realise there is a hell of a lot more to this than meets the eye. Take a closer look at the cores for example, they have to be sized correctly, so that involves making molds to make the core components and glued up in just the right way to fit the pattern print correctly, so there is the right amount of metal where it needs to be in the finished item. The pattern by itself is made up of a series of different shapes which need to be made correctly so that they can be glued together but also be able to split along the parting line, and lets not forget the pattern draft required. I havent even mentioned all the steps in the casting process yet.This is a steep learning curve but thankfully we have myfordboy's simple but very instructive videos to guide us.
