Nice. In Dutch language, but Google translates it well.
Only if it’s in your country, because in mine I have to translate it into English to understand. 
I don’t know much about gears, although it seems a bit simplified to me, but it may very well be enough for many simpler cutting projects.
Thank you so much for sharing!
In my country, it needs to be English as well. Sometimes I even need English to be translated into MY English.
Neat,
Asgat translated into something I hadn’t expected.
I’m guessing it’s the center hole for the axle.
Afraid to ask what. 
On my system, it translated to “shaft hole”.
