Post mortem for la máquina

I rarely throw away anything that can be taken apart, without taking it apart. La máquina actually had a few challenging bits, and I had to cut apart a bit of a plastic fan to remove screws, so it remains a mystery to me as to how that part of the thing was assembled.

The gear assembly with bevel gears that change the rotation 90 degrees. Quite remarkable to imagine designing or manufacturing things like this.

And this clever spline. The rounded bit goes into the rounded indentation on the shaft, protruding a bit, and the gear slides over it, so that it has to spin when the shaft spins.

Once assembled, it’s held in place by the gear it mates to. OK, enough of this. I must have something more important to do….
