Broaching internal and external gears on lathe

Hi all, this is the video of the first experiment. ... I need some planetary gears for my model. .. I had an old batterypowered drill with this type of reduction, but unfortunately too high (1: 6) and nonstandard metric module so I decided to turn my lathe to a broaching machine. .. I used the gears of my lathe that give me the chance to do almost all possible divisions. Now I can produce my own planetary gears with a 1:4 ratio If you have patience, you will find more videos on my channel of this br, br,
