Pendulum powered spirograph machine

One for the 'ould hands'.

Does anyone remember a pendulum powered spirograph drawing machine for which plans were available so 50 years ago?

Jim.

I believe the correct name for the shapes drawn is harmonagrames.

I think in the article it was called a Harmonograph.

Hi

Many thanks to both MichaelG and Tom.

Jim, since 1902, until 2006 there have been 56 articles on Harmonographs in Model Engineer. In 2000 vol 185 no. 4135 Stan Bray did an article on how to make a simple Harmonograph for a Christmas present.
