The science is not so hard: If the distance on the lever between hinge and the vertical "stamp"
is e.g 2 inch and from the stamp to the point where the weight is attached
is 10 inch, every pound will give a pressure on the stamp of 10/2 = 5 pounds. If you use a pulley like on the picture, you multiply that with the amount of strings, so 5x2 =10 pound. If you use a double pulley and three strings, it's 15 pounds.http://cheeseforum.org/forum/index.php/topic,9149.msg64830.html#msg64830
The distance from the point where you hang the weight to the fulcrum is 32 inches ( the fulcrum is not where the pusher is, it is on the far end).The distance from the fulcrum to the plunger is 10 inches.
So the MA is 32/10 = 3.2.
If you hang 16.3 lbs of weight on the arm you get 3.2 x 16.3 =52.16 lbs pushing on the follower.
To get 75 lbs of weight on the follower you need 3.2 x 23.4 = 75.
When you are pushing on 4 molds the pusher needs to be exactly in the middle of the board that is on the top of the 4 molds or the weight won't be spread evenly to each mold. Think of what would happen if you had a long 4 inch by 12 inch rectangular mold and you pressed on one end of it.
