Custom Machine Building

I'm Looking into building custom machines in the future, but I'm unsure of how to get started. Essentially I want to do cast machine, from my knowledge machines built with adjustable parts tend to come loose and chatter. I don't really know where I can find information about casting machines or even where to start. If anyone has any information about how I can contact anyone who builds machines so I can ask some questions that would be awesome. I'm not looking for the trade secrets or anything like that I just want to see how to get started. -Justin
