Pressing weight is pretty important. How many gallons of milk were you working with? How big is your mold? You should search psi on the forum to get a better idea of what amount of weight you'll need. Simple Dutch presses give great, stable pressure from low amounts of weight and are great for the home cheesemaker. You should search those on the forum too. For instance, I can put a 25 pound weight on mine, and it will act like it's 100 pounds. Now I can look at the size of my mold, determine the number of square inches, and see how many psi I'm getting by dividing that number into 100 (or whatever pound weight I'm using).
