Hi Will
I have done what you are suggesting, but on a fairly small scale. My press is a second hand wine/grape press which has a perforated stainless steel round basket and screw mechanism. The screw was simply a 3/4" BSW thread which soon started to bind up due to the pressure I was applying to the apple pommace which is much higher than needed for the easier to press grapes.
The "fix" has been to use several bags of pommace with 250mm PTFE discs layered between the bags. The discs are made from a PTFE chopping board about 20 mm thick with deep and wide saw cuts across them on the top and bottom. Pressure is by a hydraulic jack and the juice flows out through the saw cuts.
The the yield is about the same as the basket setup but is much quicker and easier. The whole setup works much better than the original screw type basket press.
