Oil Press is Running

We got the oil press set up and running. Last week we ran some sunflowers through it. Yesterday we ran some flax seed through it, but the seed was too dry and it just plugged up. Today we tried again with some water mixed with the seed. But we got it too wet. So we had to run it through the press more than once to get the oil out. We are kind of like some city slickers trying to farm. But we are figuring it out. It sure helps to ask people that have experiance what they would do.
