Hello I am new to gears. I need to figure out what type of gear I have here, and my only option to make is with a gear cutter. I dont have a hob machine or shaper. The OD is 1.865 and it has 12 teeth. When i did the calculations I came out ot 7.5 Diametral Pitch which isnt a thing apparently. When I calculated as a module I got closer to a 3.5. So i bought some gear tooth gauges that have both 14.5 and 20 degree profile. Neither of them match the gear I have. I could not find it on google search or youtube.
