Last year I build an apple grinder and press. The apple grinder I built was inspired by this one Building an Apple Grinder
The press I made was something along the lines of the one that SegmentedMonkey posted, however it didn't look as nice.
The grinder worked great, I was really pleased with the performance. However the press was a little slow, I think I made it too small. Still, in the course of a day I managed to get about 23 gallons of cider.
For next year I think I will make a bigger press and maybe two of them to keep up with the grinder.
With something like this, you will be able to produce some of the best apple cider you have ever had.
FYI, I found that a five gallon bucket full of apples would produce about one gallon of cider, maybe a little more when ground and pressed.
