Is Efficiency Sometimes Unhealthy?

By Noah Graff

For the May issue of Today’s Machining World, I interviewed Carl Hoffman, author of the new book, the Lunatic Express. The book chronicles Hoffman’s travels throughout Asia, Africa, South America and the U.S., during which he attempted to use the modes of transportation commonly used by natives, notorious for discomfort, tardiness and poor safety.

One thing Hoffman described to me is how the concept of time in Third World countries differs from that in the First World. In countries like India, the Congo and Columbia, people generally have a different expectation of what it means for things to start “on time.” People never know whether a train or bus is coming in one hour or three. Waiting for things for long periods of time, and arriving to destinations late is just an accepted way of life.

It’s mind boggling to me how anything gets done at all in places with such a low priority on punctuality. How can businesses operate if it’s unknown if workers will show up?

One would think the people of these countries would be happier if things functioned the way they do in the U.S.? It’s always so frustrating to me, knowing that precious time has slipped away that could have been used for things I care about. After all, time is a limited commodity. Once you lose it, it’s gone forever.

Yet many people I know from these places where things move so sloooooowly say they often feel more relaxed and centered when they return home to Slowville. And more and more it seems like us First Worlders in our civilized, efficient habitat are stressed out and paying top dollar for shrinks to help us chill out. We pay money to go to yoga classes and lie on the couch watching reality shows to slow ourselves down.

Is total efficiency sometimes unhealthy?

Machining Industry Scuttlebutt, The Acme Bell Tolls

Bob Atherton of RACO Industrial Corporation recently passed away at 82. In the rough world of used machinery dealers Bob always stood out as a gentle but indefatigable player. His company continues under the leadership of Jack Boescher who worked with Bob for many years before buying into the firm.

We hear that exhibitors are dropping like fall leaves from the upcoming EMO Milano show in Milan, Italy.
EMO has always been a magnificent opportunity to display wares and meet and greet, but this year it is more a conclave of woe. Hard to imagine, but the European market may be more horrible than the American one at the moment. With many builders teetering on insolvency, a significant number have decided to cut their losses.
Hopefully, by September 2010, business will have rebounded enough to justify the huge cost of exhibiting at McCormick Place in Chicago for the upcoming IMTS show.

The iPod Doctor

By Noah Graff

In the next issue of Today’s Machining World I interview Demetrios Leontaris, otherwise known as the iPod Doctor. He has a business driving all over New York City in his Aztec, fixing broken iPods, PDAs, laptops and smart phones belonging to everyone from Wall Street guys to construction workers to teenagers. On average, to fix an iPod he charges between $59 and $100 and change—a heck of a lot less then the price of a new one.

What I found so refreshing about the way Demetrios’ runs his business is that he hates to say “no” to people who need something fixed, which he admits isn’t always the best business practice. After the interview, I told him about my external hard drive that stopped working. It had about 700 gigs of memory, mostly comprised of video footage from some of my most important projects. Lacie, my hard drive’s brand, doesn’t even attempt to fix defective drives. They offered me a free replacement, but I didn’t want a new drive, I wanted my data. They suggested I send it to a company that extracts data from busted hard drives, but those services cost thousands of dollars.

Demetrios said he would take a crack at it, so I sent it to him, even though I knew that by letting him open it up my warrantee from Lacie would go bad. A few weeks later he proclaimed that after many tedious hours of attention he had both restored my data and got my drive working again. He charged me $375, which I happily excepted.

Question: Have you ever taken on a customer’s machining issue when rationally you probably shouldn’t have? Do you have trouble saying “no” to a challenge?

She’s Holding it Together

Doreen Koop is a gutsy young woman with a kitchen dream.

She is an industrial engineer, recently laid off from United Launch Alliance of Decatur, Alabama, where they make parts for Delta and Atlas rockets.

Doreen decided to go into the manufacturing business in her hometown, Pulaski, Tennessee, so she could do work for her old company. She needs ISO certification before United will buy from her. She decided to build a product she knew, a high-end spatula aimed at cast-iron cooking devotees.

Her father had made such a utensil for the family decades ago, and she decided to improve upon it and find a market.
She contacted me looking for a machine to make “Chicago screws” out of stainless steel. After grilling her about the screw and the application, I became intrigued by her story.

Doreen has seven distributors lined up for her spatula, which will sell for $32. She calls it a “Williams Sonoma” type of product. She has local Amish folk cutting her oak handles and another Amish “blacksmith” doing the metalworking. Currently she’s buying her screws from Fastenal for a dollar per piece, but the engineer in her knows they should be much cheaper.

Doreen wants to make rocket parts, but the spatula now appears to be a viable project. She is now working on her next piece, a high-end fork.

If you think you can help Doreen Koop with her quest for American-made stainless steel fasteners email her at kooped@localnet.com.

Before I talked to Doreen, I had never heard the words “Chicago” and “screw” used together in this way.

Question: What does a “Chicago screw” mean to you?

A CAM Operated Davenport in a CNC World

Last month I wrote an article about the death of Automatic Machining, in which I ended the piece with a reference to the magazine being a CAM operated Davenport in a CNC world.
Bob Brinkman, owner of Davenport, took umbrage at my comment. I am taking a moment to answer him.

Bob,
I love you and I love your product. My father made a lot of money running Davenports in World War II with the assistance of your father, Earl.
But sadly, today, the world of machining tends to look at your and my beloved Davenport automatic as a noisy representative of a bygone era. Right or wrong, the market for used Davenports, the world I live in, is in shambles. My brother Jim, my partner in our used machinery firm, Graff-Pinkert, attended an auction last week in Rhode Island and saw nice, operable, used Davenports with attachments sell for $250 each—and he passed on them. We recently traded our stock of 21 used Davenports for Maglites because we could not find a cash buyer. I know that your machines are still wonderfully productive pieces of equipment, but the market today is telling us bluntly that they are no longer valued by many buyers.

As always, I wish you all the best.

Letter from Bob Brinkman

August 11, 2009

Dear Lloyd,

To quote President Ronald Reagan, “There you go again.”

In your article on the demise of Automatic Machining you imply that Davenport is going the way of Automatic Machining.  “A cam operated magazine (machine) in a CNC world.  The comparison could not be farther from the truth.

In spite of my repeated advice, Wayne Wood could not quite understand that he had to get engaged in the business, develop new perspectives and improve his product.

In comparison, we at Davenport have constantly improved the machine, the parts and our customer service to the point that we are now considered the only alternative for spare parts.  Lower prices, highest quality, and extensive inventory continue to provide our customers with a superior customer experience.  Not only that, our machines continue to produce millions of parts a day because the Davenport is the most economical, efficient and cost effective way to produce these parts.

Sure, CNC has its place and is very effective for many applications.  But the thousands of Davenports running out there prove that the machine is still viable and will continue to be.  Our HP servo driven machines can do many of the things a CNC machine can do at a fraction of the cost.

We intend to continue to support our customers with the best in parts, service, and support.  When I took over in 2003 our motto became, “Davenport, Another 100 Years”.  As the only remaining American made screw machine builder we would appreciate your support instead of your repeated derision.

R. J. Brinkman

My Beloved Bridgeport and KitchenAid

By Lloyd Graff

Two icons of American mechanical ingenuity I encounter every day are my Bridgeport Mill and KitchenAid mixer. It struck me that their fortunes are going in different directions.

This last weekend, just a few days after the announcement arrived that Hardinge Corporation, which owns Bridgeport, is cutting back production at its flagship Elmira, New York, plant, the new movie about chef, Julia Child, Julie and Julia, made its debut.
Julia Child loved her cobalt blue KitchenAid, and it now resides at the Smithsonian museum in Washington.

More than any other personality, her warmth and unflappable style popularized the cooking TV show as a staple of television. For me the best shows on the tube today are on the Food Channel. I find Altan Brown to be the most creative and interesting TV personality on the air. The Tribune company’s stake in the cable channel is the bankrupt company’s most valuable property aside from my beloved Chicago Cubs, which are about to be sold.

Cooking is on the ascent and Whirlpool’s KitchenAid division is still cranking out mixers in the United States and doing well. The K45SS model my wife Risa and I have in our kitchen is used several times each week. It’s 30 years old, but has never faltered. We recently bought a new dough hook for it online and it arrived two days later. The basic product sells for $199.00 on Amazon, which is the same price it sold for 70 years ago.
Bridgeports’s fortunes are not so sanguine. While the product is beautifully designed and still incredibly useful, it has been in decline since it was sold off by Textron to a leveraged buyout firm in 1986. They immediately suffered a strike and struggled financially as CNC competitors eroded Bridgeport’s market dominance. In 2002, Hardinge took over the battered remains of the company, but its fortunes have gone the other way from KitchenAid’s.
I love both my KitchenAid and my Bridgeport. They have both helped make my “bread” for decades without ever failing.

Mismatched Materials Produce Self-assembling Gears

There’s been a breakthrough in the production of tiny gears used in medical instruments and electronic mechanisms. July 23, the NewScientist printed an article about a new technology which enables gears and cogs to make themselves.

The components are formed from discs that buckle into shape after a change in temperature, and the team behind the study says the technique can produce complicated bevels or curves that are difficult to produce with traditional methods.

For a decade, engineers have been experimenting with materials that spontaneously bend into shape. A thin metal film deposited on top of a heat-expanded polymer such as PDMS will buckle into an ordered array of wrinkles when the polymer is cooled down.

Xi Chen‘s team at Columbia University in New York City realized the technique could be used to produce the regularly spaced teeth of a gear without having to rely on costly etching and grinding methods.

So far the researchers have tested their technique at the macro scale, producing simple and beveled gears 6 to 25 millimeters across, but Chen says it can be readily extended to the sub-micrometer scale – something he plans to do soon.

Do think micro- and nano-manufacturing will be a viable business for your manufacturing operation in the next few years?

National Acme Musical

In December 2004, a stage version of Mary Poppins debuted in London, based on the story’s original books from the ‘30s and the Disney film from 1964 which I and several generations of kids cherished growing up. Some might say producing a live remake of the story is just an easy unoriginal way to make a buck. I say it’s taking a great product that’s become somewhat neglected and making it appreciated again in today’s world. In a way it’s similar to taking a 1960 Acme and refitting it with the accoutrements of 2010 CNC controls.

In September we are going to see some major auctions with dozens of 3/4” RA8, 1 1/4” RB8 and 1 5/8” RBN8 Acmes. These have always been the primo sizes of this genre of multi-spindle screw machines but never have so many poured into an already saturated marketplace. These machines from the 1960s, 1970s and 1980s are still perfect for high-volume automotive work, but in an 8-10 million unit market downshift, the supply chain is soggy with capacity. This could change quickly if we reach 11 million in 2010 and 12 million in 2011, which may happen with a rejuvenated GM.
   
I would not be surprised if the Acme rebuilders like Champion, Doverspike, Detroit Automatic and Jem begin to see a significant bump later this year. The beefy Acme design, now 60 years old, is still viable because spare parts are readily available from the Detroit dealers. Companies like Sieb & Meyer produce sophisticated controls which turn the rebuilt National Acmes into serious hybrids, much cheaper than new European machines.
   
Mary Poppins with Julie Andrews and Dick van Dyke as the happy chimney sweep was a Disney classic. The old movie converts beautifully to a stage musical. Still, an old chimney is probably much easier to clean than a 40-year-old Acme out of Saginaw Steering.

Question: Would you buy an Acme converted to a CNC? Why or why not?

Harrison Ford meets CNC Swiss

By Noah Graff

Hey all you CNC Swiss medical component manufacturers out there. Ever wonder how companies are using your parts when they leave your floor?

Recently medical device maker, Medtronic Inc., received a subpoena from federal prosecutors about a former army surgeon who is being accused by the army of falsifying data from his research on the company’s bone-growth product. Medtronic gave Dr. Timothy R. Kuklo nearly $800,000 over the past three years to conduct research on the company’s bone-growth protein called Infuse.

A sinister doctor falsifying medical research for a multi-billion dollar company—haven’t I seen something like this before? Ah yes. The Fugitive!

Question: Should the president of a medical device company be held responsible for a dishonest researcher?
