CPR wood automaton with available plans

Here's a video that shows a fun automaton designed by Ken Schweim. He has written complete construction plans describing how to build it. It has 36 pages, 36 photos, and 26 blueprints with complete step-by-step instructions. It is available for download for a cost $10 payable through PayPal. This might be a great way to get into making wood automata.

You can purchase and download plans for this wood automaton at Ken's Devil Dog Automata page.

The whimsical machines of Edmund Dohnert

Edmund Dohnert designs machines that are meant to be amusing celebrations of mechanical movement. Shown here is a piece titled Victor Rat Trap No. 3.

The artist describes this machine:

In a deliberate escalation beyond Victor Rat Traps Nos. 1 and 2, this one is powered by not one, but two rat traps! Both springs are connected by a steel rod, which is attached to a Swiss cheese-like structure that has a cord wrapped around its edge. (The "cheese" is mounted off-center so as to even out the pull on the cord over the full range of the springs' travel.)

This cord pulls the springs back, and through an arrangement of pulleys, connects to a crank-wound gearbox on the right. The gearbox's output shaft connects to a vertical shaft running through a support structure, on top of which is a 'planetary gear' arrangement with two hollow spheres attached.

When the vertical shaft rotates, not only do the "planets" rotate about their own individual axes, they also orbit around the central shaft (hence the origin of the term 'planetary gear'). Connected to the main gearbox is a second gearbox that operates a small fan which not only helps control the speed of the machine through air resistance, it creates a unique whirring sound.

While the machine only runs for about 30 seconds, it's quite interesting to watch, for the movement is reminiscent of a medieval astronomical orrery.

Automata-maker Dug North and his workshop

I thought it might be fun to give you a glimpse of my workshop and some photos of me in it.

The shots were taken by the talented portrait artist, Adrien Bisson who also resides in Lowell, Massachusetts. The photographs show my workshop, some parts of the wood clock I am making, and a prototype automaton that is in the works. The workshop it is actually built into a century-old walk-in vault.

To see more photographs from this shoot, check out Adrien Bisson's photography blog.

And, as always, thanks for reading The Automata / Automaton Blog!
