    Looks like Jack the Flash is buzzing through the room building giant rivets. Beauty of a forge beast!

    That is a big fella! The mass of the base is...Geez, I dunno...massive I guess...no words.

    This pic gives it some scale.

    Wonder if this was an inspiration for George Lucas and Star Wars.

    Color picture and a bit more background...

    When most of us think of analog computers we tend to picture racks of op-amps and giant plug boards for programming but simple mechanical computers can quickly solve problems that tax algorithm writers.

    I recommend you read this article from the Scientific American Computer Recreations column for some examples of really clever analog computers. My favorite is the refinery locater computer made with string, weights, a board and a washer.

    I came across a rotary cam controller that was controlling the timing/operation of a food factory packing machine, the machine had a computer but its mechanical/pneumatic functions all came off this cam device. To be honest it was more reliable than the PC, just a shaft with discs on it which contained slots in specific places.
