I am still looking for a gear lisp that will allow me to draw a 128 tooth gear. I have written all the data for the spline below. I am not an expert at CAD by any means, and do not know very much. Thank you for your time. -Tim # of teeth = 128 Nor. Diametral pitch = 8 Nor Module =3.175 Pressure angle = 14.5 Pitch Dia. = 406.40 Base dia. = 393.455 Form Dia Max = 399.71
