Finally made my Sake press. Still waiting on the fabrication of my press plate (HDPE 3/4 disc, with 1/8 in inset for an o-ring around the edge).
I am using a 12qt stainless pot with the handles removed. Dremel is my friend.
Working out how to get the sake out of the pot. Either a tap in the press plate with a barbed nipple, or putting at the bottom of the pot an elbow port and having the tube run underneath and out the base via groove.
Still need to add a handle to the main threaded rod.
