Could anyone help me out here as the figures don't seem to make sense. From what I have been able to glean from various internet sources I require a 135/127 tooth combination gear – but how does it work out? 135 devided by 127 = 1.063, yet 0.125" (1/8"
devided by 0.1181" (3mm) = 1.0584. Is this just the nearest they could get to the true figure, or am I missing something?
