Wow just wow!!! That is cool, I am still trying to figure out how the moving parts actually work. The model of the steam engine blew my mind with so many different parts that work together. I could understand it if they made the parts individually and assembled them. Am I wrong or did he not say it came out of the machine assembled. I can under stand how the dots of plastic work, but to make a shaft that runs through a housing and functions is mind blowing to me. If it’s that accurate why make the plastic piece, why not just go on to the C&C machine. I want one!!
