Taking Stuff Apart

The other day, I was reading one of several new biographies that have been published about Henry Ford. There have been a slew of books recently, because this year marks the automotive pioneer’s 150th birthday (Ford was born on July 30, 1863).

When he was growing up on this family’s farm, Ford often passed away his free time by taking apart mechanical objects. Richard Snow, author of I Invented the Modern Age (Scribner), says Ford loved playing with tools and disassembling objects. In fact, his sister, Margaret, once fondly recalled, “When we had mechanical or wind-up toys given to us at Christmas, we always said ‘Don’t let Henry have them. He just takes them apart.’ He wanted to see what made them go rather than just watching them go.”

In particular, Ford was fascinated by the intricate movement of clocks and watches. According to Vincent Curcio, author of Henry Ford (Oxford), before he started tinkering with horseless carriages, Ford wanted to start a company to mass-produce watches.

“If he could make them for 30 cents each and sell them for 50 cents, a decent profit could be made, provided he could manufacture 2,000 per day,” says Curcio. “Ford even found a partner and worked on designing the requisite machinery.”

Ford’s fascination with precision and mechanical movement eventually helped inspire the moving assembly line several decades later. “Everything moved quickly, like the second hand on a pocket watch,” says Snow, describing the operation of Ford’s revolutionary Highland Park plant.

Taking things apart is still a common trait among many engineers. If you share this passion, I suggest picking up a copy of a new book entitled Things Come Apart (Thames & Hudson). It’s filled with interesting photos that showcase the inner workings of 50 everyday objects—everything from a chainsaw to a sewing machine and a camera to a piano. And, in case there are any aspiring Henry Ford’s out there, there’s even a mechanical watch and a digital watch.

The book features exploded views of all the parts and components that make up each product, including everything from the smallest screw to the biggest gear. With 175 photographs revealing 21,959 components (plus several short essays about the joy of disassembling products), the book offers an interesting perspective on the nuances of manufacturing.

“The thrilling part about disassembling an object myself, even before the photography, is the opportunity to understand the manufacturer’s challenge,” says Todd McLellan, the author of Things Come Apart. “I gain a better understanding of how the item works and, in turn, a greater respect for it.”

If more people were exposed to this view of the inside of products, perhaps it could help the general public gain a better appreciation for the basic concepts behind product design and assembly.

Did you like taking things apart when you were younger? Did this inspire you to become an engineer or pursue a career in manufacturing? Do you still like taking stuff apart today? If you have any interesting stories to share, I’d love to hear about your disassembly experiences.

Never in a million years did I think I would make a career out of the experiences I had as a youngster. Taking things apart was easy--it was putting them back together that taught me never to give up. I may have had to wait awhile to trade someone out of a part I needed, or sometimes I just need to get the right tool. I grew up pretty poor in rural Missouri and fixing things often was the difference of being able to go to the fishing hole. Learning that I couldn't braze my handle bars by melting solder with the kitchen stove was dangerous to say the least. The real problems came when I started blowing fuses, no breakers back then. I can go on forever. I used to think my step dad was mean for never helping me but now I know it was one of the best things he did. Now when I tackle something I don't know I use my camera to help my memory. I will also pass on that it is wise to replace piston rings no matter how good they look, unless your in need of a smoke machine.

WOW! That makes another thing Henry Ford and I have in common, as if enlightening the manufacturing field with our collective towering intellect wasn't enough. I also liked (and still do) to take things apart. Even when I didn't put them back together, I still learned something. One of my "inventions" that didn't work was an arc lamp. My mother couldn't understand why the receptacle in my bedroom kept blowing the fuse. I learned that you can't make an arc lamp from flashlight D-Cell center electrodes and a lampcord. I also learned that curiosity alone can't fill the gap between theory and practice.

Behind the Scenes at Ford's Michigan Assembly Plant

People are the heart and soul of the 2012 Assembly Plant of the Year. This slideshow shows some of the men and women who build three different types of electrified vehicles alongside traditional gas-powered cars on the auto industry’s most flexible assembly line—Ford’s Michigan Assembly Plant in Wayne, MI.
