Of Fail-Safe Joint Integrity For Critical Applications |

CANNED!
An aluminum can manufacturer called Stage 8 after an industrial accident
that infuriated the owner, but luckily, didn't get anyone killed.
If you've never been inside a large factory, you can’t imagine
the size and speed of the machinery involved. In this case, machinery
churning out more than 200 cans a minute was being driven faster and
faster to meet production quotas. When you increase the average operating
RPMs of any piece of machinery, you also increase heat, friction and
vibration. In this case, a 3,000 pound, flywheel, five feet in diameter,
came off its housing and smashed through the wall. A little thing like
a cement and steel wall didn’t slow the flywheel much: it continued
its path into the parking area. The owner of the company also owned
a beautiful Corvette, the apple of his eye. But the apple got a coring
when the flywheel sheared it right in half.
When the tears stopped, the Corvette owner, who had installed my locking
header bolts on his prized car, called me up to see if we could create
a locking system for that gigantic wheel of death. Of course we did,
and now it stays right where it belongs. |

DAM!
Dams work not only by storing water until it’s needed, but
by moving it from one place to another. When you move it in a way that
also captures the kinetic energy of the water, you can transform that
energy into electricity. When you build a dam for hydroelectric purposes,
it’s more than a cement pond: you also install turbines or propellers
turned by the weight of the water to create electricity. As you can
imagine, the equipment is huge, and even a small part can contribute
to a huge loss.
The 130-foot diameter propeller that turns at the bottom of a dam
in Argentina once needed regular servicing because of the 116 nuts
that, with rotation and pressure, would work their way loose and compromise
the functioning of the propeller. When that happens, you don’t
just send in a guy with a big crescent wrench—you have to drain
the entire lake! In this particular place, the lake took a year and
a half to refill, causing all sorts of problems with water supply and
power production. When you have regular down times of eighteen months,
you take some time to think about maintenance and prevention before
you build another dam. In 1992, when the dam needed reconstruction,
the hydro company contacted us to make locking nuts to replace the
old ones, which had continually failed them. We did, and we haven’t
heard from them again. The problem with making a product that works
100% of the time is that your customers don’t need to buy another
one!

GO
ARMY!
A few years ago, we were contacted by a company planning
to subcontract with the military for transport vehicles. They needed
locking spindle bolts on their Humvees. But before the sellout, Stage
8 had passed every test the military set for us. We've also made
locking spindle bolts for earth movers and 4 wheel drive vehicles. |

THE
LIE
When I first invented my locking header bolts, I went to the
top three automotive manufacturers, and showed them my product. A way
to keep bolts from coming loose and falling off—who wouldn’t
want that? The company reps looked me right in the eye and lied, “Our
bolts don’t come off,” they said. “Whose
bolts are lying all over the nation’s highways?” I asked,
exasperated. They each named one of their two competitors.
There are two reasons companies lie about their bolts. One is about
the impact on sales of admitting any imperfection in the product. You
just don’t do it—unless you’re forced to by a product
recall! The other is about planned obsolescence. If you replace your
exhaust system but the bolt loosens up, you’ll be buying a new
header gasket long before you would have otherwise. Manufacturers want
to sell you stuff on a regular basis—not just once. A truly satisfied
customer, when sold something built to last, doesn’t need to
buy another one next month or even next year. People in sales hate
that. Fifty years ago, things like washing machines and ovens were
built to last twenty years: they were major purchases. Now, you’re
lucky to get a one year complete warranty on appliances, computers
or cars. Planned obsolescence is built in; things fall apart because
of inferior components that don’t last. It costs more to repair
some items than it does to buy a new one, so more things end up in
landfill when they should, by all rights, still be operational. When
a car manufacturer uses lower grade steel on something as simple as
a bolt, it can end up costing a lot in time and associated repairs.
It’s also a safety hazard, because when bolts work loose, people
can get hurt. It happens all the time—cars, lawn mowers, boats,
airplanes. And there’s no reason for it, beyond corporate greed. |

AN
OVERSIGHT
If you wear glasses, you’ve probably been mightily annoyed
when the screw dropped out of your glasses and then fell into the car
seat, never to be found again. If you’re one of those organized
types, you might even have had an extra case with a tiny screwdriver
and extra screws so you could repair your glasses—providing you
could see what you were doing without your glasses! And unless you
have the manual dexterity of an eight year old on a mission to get
big candy out of a small box, forget it.
We made tiny locking eyeglass screws for a glasses company, and they
were fantastic. With our locking screws, people’s glasses lasted
on average, two years instead of four months; the previous average
life expectancy of their glasses. Market research has found that if
glasses break inside of four months, customers tend to return them
for replacement of refund, but after four months, they think the breakage
must be their own fault. So, the planned obsolescence for their eyeglasses
is right about at that four month mark.
You might say we screwed up. Our locking glasses screws lasted so long,
they negatively impacted sales. The product was too good; it lasted
longer and people were satisfied with their purchases. The company
decided to return to the cheap screws they’d used before.
