Not a battle at all Sandro, but rather an interesting topic.
So Jeff, it's actually No6 gauge, like woodscrews used to be, and 32tpi, and not 6/32" at all?
I spent yesterday morning with my engineer friend, carefully measuring the Norton journals, bores valves and guides. The book gave all the sizes in thousandths of inches, while my mate painstakingly converted it all to mm!! Presumably his gauges are all metric.
Anyway everything passed with a clean bill of health and I'm ready to start preparing the engine... Oh yes!!
