The threading table for my Vevor metal lathe was very inaccurate, so I set about to come up with a much more accurate thread cutting table. With five gears that can be swapped out, It's possible to approximate any arbitrary thread pitch with surprising accuracy. I also tried making some wooden gears to explore the possibility of just making custom gears for it.

I have uploaded my Python script and spreadsheets to github:
