Making Mechanical Marvels In Wood - DIY Book

Here's a book that should interest you makers out there. Making Mechanical Marvels In Wood

This book is not unlike Making Wooden Mechanical Models which I reviewed here. There are, however, some important differences between the two books.

Like Making Wooden Mechanical Models, this book isn't specifically written for automaton makers. Both books feature basic wooden machines as finished projects in themselves.

Making Mechanical Marvels differs in that many of the projects in this book are key building blocks to making contemporary wooden automata. For example, projects such as the cam and follower, the Scotch yoke, the fast-return actuator, and the Geneva wheel are all elements often found in an automaton.

The projects in this book are very handsome and would make nice gifts. There's something inexpressibly classy about machines made of wood.

I bought Making Mechanical Marvels bundled with Making Wooden Models from Amazon.com and I'm glad I did. The two books really compliment each other. I consider this book to be Volume 1. This book has very clear instructions and drawings to get you up to speed making wooden mechanisms. Making Wooden Models is equivalent to Volume 2 in which you tackle some more complicated projects.

The book has well-drawn line diagrams and a series of color pages in the center. The instructions are very well written; I would feel good about giving this book to a new woodworker or youngster looking for a science fair project.

The book concludes with some handy shop tips and jigs -- a nice bonus. I have learned a great deal from this book. Don't overlook it as a resource for building wooden mechanism.

Reciprocating Motion from Rotating on Same Axis

One reader of The Automata / Automaton Blog wrote to me with an interesting question. He wrote:

"I'm looking for a simple mechanism to convert rotational motion to reciprocal motion along the SAME axis as the rotation, not perpendicular."

I decided to investigate potential solutions in one of my favorite books on mechanisms, Five Hundred and Seven Mechanical Movements. Below are some of the solutions I found listed by the numbers that appear in my copy of the book (Astragal Press, 1995).

• 95. Oblique disc imparting rectilinear motion to rod resting upon its surface
• 106. & 107. Uniform reciprocating rectilinear motion produced by rotary motion of grooved cams
• 136. Crown tooth gear with rod pressed against rim
• 143. Sliding worm screw and toothed wheel
• 165. Circular to rectilinear motion via waved-wheel (or cam)
• 167. Drum or cylinder with endless groove and follower
• 237. Crown-ratchet (driven by crown, not pawl)
• 272. Beveled disc with follower on its circumference.
• 351. Partially toothed pinion and rack with return mechanism

I have probably missed a few in the book, and there are certainly many more possible solutions.

Heron and Fish Automaton Video

Another video of some clever work by the artist I know only by their YouTube username: kitundu.

This piece features an interesting approach to creating a wave effect in the pond. There are also some nice detailed views showing some very practical information -- such as how to keep a cam follower on a cam.

Hummingbird Automaton with Scalloped Cam

Here's an interesting use of a scalloped-edged cam to create a very fast reciprocating motion of a lever. The lever, in turn, pulls a string to cause the humming bird's wings to beat.

Automata and Mechanical Toys by Rodney Peppe

I have said in the past that if you want to make a wood automaton, and can only get just one book, Automata and Mechanical Toysby Rodney Peppé is the book to get.

This wonderful book is currently available in hardcover at amazon.com for 31% off the regular retail price. This is a great deal.

The book is printed on fine glossy paper and is full of color photos (160 in all). The book profiles over 20 leading automata-makers, and provides step-by-step instructions for making an automata test-bed. There is also a section teaching you how to make ten fundamental mechanisms.

One of the best things about this book is that there are scale patterns to copy and use -- cams, gears, pin-wheels, ratchets, and even a Geneva mechanism.
