As requested: the new plunger assembly. Notice the fine craftsmanship of the fir plate. Yes. Sarcasm. I was in a flap of excitement the day of crushing and pressing, and we were trying all kinds of quick things to see what would work best. That’s my excuse. I essentially chopped down and trimmed corners off a piece of 2×10 fir so that it would be smaller than the bucket diameter, but maybe only by an inch or so. That’s key. It needs air, as I’ve previous mentioned a thousand times. You want to maximize the spread of pressure while ensuring good airflow. Note: bricks don’t work. They just break.
Note that none of the pieces are attached.
