This is an interesting vid clip about what they term as a "Do
Nothing Machine". Although it doesn't seem to have any practical
purpose at first glance, I certainly wouldn't say it does nothing.

There are a number of interesting mechanical principles that are not
commonly known. It would seem to me that this craftsman could work
with a local school industrial arts teacher to come up with a great
presentation for students.

The various mechanical principles could be explained with a foil
presentation and hand out sheets for reference and study. Then the
principles could be demonstrated and carefully observed by the
students. I would think this would be a fantastic device that
would be great as an education tool.

This man is obviously a very skilled craftsman, and I can only
imagine the thought and the hours he put into this project. He must
have quite a variety of tools in his shop as well.

Hope you enjoy the vid. http://tinyurl.com/5tokso

That was an awesome invention! Reminded me of the inside of a 70s Italian photo
copier...

Wonder how he kept the friction so low?
