I couldn't find the english version of this video but it's cool to watch ... 9 minutes long as you watch the guy hand tool and create some of the parts then puts it all together (time lapsed). It really works.... okay not really REALLY work because where the heck are you gonna find 12 spark-plugs THAT size... still very neat video for gear and motor heads.
