It seemed that the plastic was acting like a sponge.
I would put full pressure on the powder.
But it didn’t come out dense all the way thru a 1/4” thick puck , and even less on a 3/8” thick puck.
So today,
Instead of using the plastic on the bottom steel plate , I started using a piece of thin Aluminum.
I made the aluminum plate out of the bottom of an empty cat food can.
So far the pucks look denser.
After they dry out I will see how much more dense they are after I grind them up.
