How to Make Pinwheel Gears, One-Way Cranks and Worm Gears, by Marc Horovitz

Pinwheel gears are commonly used in automata. This book describes two methods of making them, step by step. Worms and worm gears for slow-speed action are described in detail, including a two-way worm. One-way cranks to prevent damage to automata are also covered. A description of how gears are used in a gravity-powered automaton finishes out the book. 

27 pages. This book is available only in downloadable PDF format.

Words from our customers...

Hi Luise, 

We cannot fault this company - the kits are reasonably priced, well packaged and fun to build! Instructions are clear and easy to follow (by our 14yr old son) plus there are videos available online to assist with the trickier bits! Customer service also goes above and beyond - when we discovered an incorrect part in our box, communication was very efficient and a replacement was sent out to us immediately -in France!! We would thoroughly recommend Timberkits avd their products!

Best wishes,


Thank you for sending me so promptly the Guitarist kit.
I thought that I must write to you to tell you how impressed I was and am about how the kit is make, put together and is presented.
I bought wooden self build kits from all over before but I must say yours is the best I've ever purchased. Thank you.
Keep up your great work.
Best regards
