The Base

In this case I picked a plastic planter. The size was 45cm diameter at the top. This one was rimless. As you'll see later, it makes a great base, but it's overkill. A 35cm diameter pot works well, depending of course on the size of the press. With this size, you could mount any press, it's that heavy.

I drilled holes in the bottom, six equally spaced, you'll see why in the next picture.

This plate is 250mm diameer in 4mm thick mild steel. The holes are 6mm, and correspond to the holes on the plastic base in the previous picture.

This is just the two together with the holes lined up.
