OK, It's still not perfect, but It is working better, It is a cheap and low maintanance way to make a good block of ice. Things that you need: Containers in the form of a cylinder(I use paint cans from Ace Hardware Stores, they are $2 and change and are coated inside, they don't rust), a round piece of packing foam, this foam is flexible, with a smooth finish, the ice does not stick to it, it is used to protect and to insulate packages or boxes. You fill up the container and then place the foam on the top where it ill float. If you want to cover the top of the container it will work even better, this way you are making sure that the water is freezing from the bottom up, since the ice will be forming there first, the bottom of the container will not deform or bulge, the last area to freeze is the top part of the water that is in direct contact with the foam, under the pressure, the foam keeps on bending, the top of the ice should not crack. I take out the block of ice and with a nife I flatten the top a little bit, this end does not have to be perfectly flat, it needs to be good enough for the theeth of the machine to get a good hold of. In a small freezer I am making 16 blocks of ice at once.
