The Inch version of Module is not circular pitch, it is DP, Diametral Pitch. And the calculations are just as easy in that system, you just divide rather than multiply. In your example, if you had two 30T gears at 4DP then the centre to centre distance is 30T / 4in, ie 7.5in. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
