Is this grader going to have cab, or will it be an open station model?
@Nathan,
when you look at the tables for strength of such plastic gears (POM), you will find, that the values are not much lower than for normal steel, like C45 (sometimes even higher). I use the plastic gears because they are running quieter.

I buy my gears at Mädler in germany:

I will make an open station model, because I like this kind.
