It all comes down to what losses you are willing to tolerate and how much manual labor you are willing to invest. As I said, for a small batch, you could do the entire lot by hand.

Don,
There's many a house "in the old neighborhood" that has just such an arrangement in the cellar. It works perfectly well, is simple and cheap to boot.
Consider using a hydraulic jack rather than a scissor jack. With a scissor jack you apply force in a circular manner, across your wobbly braces, but a little pump hydraulic jack lets you push up & down along the braces. It should be a lot easier & safer.
Also, consider using a board & bungee straps to hold the jack up toward the joist. I would anchor the upper brace to the joist as well.

For pictures of a press that uses a car jack go to:
Some very nice photos of other processes here as well. HTH
Nice setup. I think it would make more sense to have the jack underneath and have a solid 4x4 attached directly to the platen. That setup has just got to be dirt simple. A drilled square basket made from 12" or larger boards, the juice catcher, the hydraulic jack and the platen/pillar setup. I just checked the price at an online auto parts place and a 2 ton hydraulic jack is $20 Cdn.
Trouble is that a hydraulic jack doesn't have anywhere near the range of motion of a sissor jack. If placed underneath the sissor jack wouldn't have a wobble problem either.
I'm going to consider this for next fall.

There are other hydraulic jacks out there with longer motion. I saw on e-bay the other day some 8 ton jacks with 18.5 in range. Bill
It's a little hard to see but the jack _is_ underneath. If you look closely you can see the jack handle protruding in the second and third photos. HTH
Thanks to everyone that gave me feedback. I think I have what can be a working design. Now I just need the time to build it. Like they say, work is the curse of the drinking class.
Thanks again, Don
