Method of cutting herringbone gear
I need to cut a herringbone gear for a repair job. Not that it really matters but the gear is 8" in diameter and over 60 years old. I can't figure out exactly how this was done. I have cut plenty of gears but never one like this. My question is this. Would it be possible or appropriate to cut two gears with opposing angles and then attach them together? I don't see how you can cut the gears without destroying the opposing teeth in the process. I assume they were made with a form tool in a mill but not sure. Thanks.
