Do Nothing Machine

[edvga]

Have you noticed that, no matter how long you watch it, one slider will never colide with the other on this busy cross section?

[uprightgirl]

I think it could draw some eliptic locus if you put a pen to one of the side arms

@youtship

Sorry I overlooked your full description which has mentioned about elipse drawing already.

Anyway, Great Idea!

i a meccano set but i dont know how to make the sliding connections, how do i make them?

[swanbrown]

Theat's great! 

and to think I've been doing all my nothing by hand.

I bet I could get a lot more nothing done with one of those.

The trajectory of any point of the handle is an ellipse.

In the middle point between sliders this ellipse = a circle .

Holding it at this point you can motorize it easilly.

Thanks for the commentary

This specific mechanism is called a nothing grinder.

The first time I saw this movement as a toy was 48 years ago.

I was told that it was called the "b. s. grinder".

Not far from the name you called it.

Thanks for the commentary.
