These three presses, from top, an example of a screw-top press from Lebanon (1738), a Fawkner press (1838), and a Gutenberg style press, the original Gutenberg was invented in the 15th century.  I wanted to show these as they are examples of wooden presses that have through the centuries all used a square frame.  Our press is unusual in its A-frame design, which will be fascinating to use.  The press we are designing is also exceptionally light-weight, thus it will be fascinating too see what pressures can be achieved through the lever mechanism.
