Another set of photos of the Oostendorper watermill near Haaksbergen, The Netherlands I posted about earlier, this one:

I went back to try and get some shots of the inner workings of this water mill, but I only managed one as there were too many people inside. First, a shot from a different angle:

Only one of the water wheels was turning, powering the oil mill:

The shaft of the water mill goes into one end of a reduction gearbox, you can see the gearbox' outgoing shafts entering the photo below on the right:

The shaft in the back drives a vertical cog wheel, which drives a horizontal cogwheel with two vertical, small milling stones attached to it. These milling stones roll over a vertical larger milling stone you see at the bottom. The linseed or rapeseed is crushed between them into a oily pulp, which is then processed in the next stage.
The pulp is put into a hollowed wooden block with a wedge on top and a small hole in the bottom. A vertical battering ram is used to squeeze the oil out. Here's a picture of the battering rams:

The bits sticking out of the axle lift and then drop the battering rams on top of the wedge.
