thanks, that video led to this one https://www.youtube.com/watch?v=uJnovsAhf-Y a straight forward build I think.

Corn is dry and olives are wet so might just gum up the grinder. I think the screw press would work much better.

Ancient olive oil operations crushed the olives in presses with huge stone wheels to create a pulp. The pulp was placed between layers of coarse cloth and then squeezed in a large screw press. I may be able to find pictures from my time in Turkey.

Wonder where the rest of my post went? Modern olive oil plants use centrifuges to separate oil from crushed pulp.

There was a farm southwest of San Antonio that was raising olives. They used a centrifuge to remove the oil from the pulp. The wife and I did a tour of the place a few years back.

it seems to handle the olives OK, being a flail mill the clearances are fairly coarse. I have rebuilt and repaired a couple of flail mills over the years so the idea appeals to me, but I am not in a hurry so I’ll see if there are any insinkerstors at the local recyclers.

Sandy Oaks Olive Orchard in Elmendorf. Closed since the owner's death a couple years ago.

I made cured olives in a drum with lye and salt, but I never tried to make olive oil.

I guess I am assuming that the oil that comes from the fruit is different than the oil that comes from the seed. But I only know about wine presses. If you did that to grapes your wine would taste like acid.

But it looks to me like those olive oil presses are using crushed seeds too.

Here's a photo of the adapter and press that I added to my engine stand, so I could press chokecherry mash. Might give some ideas.

The wine presses that I drew had pretty hefty hydraulics, and If you went too Rambo on the wiggle stick, you could press the grapeseeds into particleboard-like hardness.

This was totally undesired because it made the whole press seize up. They broke the coupling which attaches the gear reduction box to the auger. They broke the screen drum loose from its mountings, And it spun with the auger, before the idiot let go of the hydraulic lever.

We had to extract the encrusted auger with a winch for decontamination. That was just the beginning of the repairs.

Instead of relying on the pressman to control the machine, we added pressure relief valves that took the procedure more out of his hands.
