I didn’t get the focus quite where I wanted, but I think it works anyway. This is another section of that same chain from yesterday that went around the wheel from the day before that. It goes around this spool, and then another at the bottom, and somehow works it’s way back to the wheel again. Since I haven’t cranked the handle on the wheel to see what actually happens, I can’t be certain of this, but the grate that you can see there is what sorts the chaf out of the corn, I believe. But, since I’m sure not that this is a corn sorter, I could be wrong on all of that.
