Hi there, I am currently modelling a product for a university project, and need to model different size spur gears,one with 50 teeth (approx 51mm OD), and one with 10 teeth(aprrox 11mm OD).I need to build a working prototype so I need to model the gears then create DXF files to laser cut these from 6mm sheet acrylic. Does anyone have any files of gears? or know of a site where i candownloadsome? ( the ones in the files section dont' help) I find the whole business of modelling gears very complex. I know how to pattern them easy enough,I'm just findingit difficult to get the larger cog to mesh with the smaller one.Ifanyone can explain how to model the teeth correctly that might help.
Thanks in advance
