I guess if you have some power you may like to make some oil using a cold press machine, like the ones at the Oil Press site. But does anyone know what to do if you don't have power and still want to make, say, hemp seed oil?

It would be slow and tedious, but a vise is a poor mans cold press.

One method would be to purchase a 20 ton hand operated hydraulic shop press (about $200) and adjust the size of the surface area between the compression plates until one gets all the juices out of the plant. Separate the oil from the water.
