The myth of the “big society”

The public don’t want to get involved. Do you blame them?

James and I have a column in the mag tomorrow in which we critically analyse David Cameron's "big society" big idea.

In the meantime, a couple of related things.

To what extent do people want to be part of this "big society" and accept the Tory invitation to "join" the government? Gary Gibbon of Channel 4 News asked Cameron where the evidence is that people want to be "prised away from the telly" in order to run public services or their local communities. The Tory leader said he "profoundly" believed that people want to be more involved.

Really? This poll from Ipsos-MORI asked voters if they wanted more involvement in the provision of local public services. Only one in 20 wanted "involvement", whereas one in four wanted "more of a say" and half of them only wanted "more information". (Incidentally, the poll also showed that less than a quarter of the public agreed with the statement: "There is a real need to cut spending on public services in order to pay off the very high national debt we now have.")

Another, earlier poll from the same company asked voters to what extent, if at all, they would like to be involved in "decision-making" in their local communities, to which 50 per cent responded "not very" or "not at all". And when asked about being "involved" in the running of the country as a whole, the percentage of "uninteresteds" increased to 55 per cent.

People seem to opt for quality over control. My colleague Tom Calvocoressi makes an interesting analogy between the "DIY government" being proposed by the Tories and the do-it-yourself checkout procedures on offer from Tesco self-service tills.

In a busy superstore, with long lines for the checkout, self-service seems like a great idea to start with, supposedly speeding up your progress and handing power and responsibility to you, the customer. But then the barcode won't swipe, "approval is needed" for your carton of milk, the bags have run out and the whole procedure ends up taking you even longer than queuing for a cashier.

Ultimately you conclude that it's quite nice having someone who is paid and trained to do the job for you. We have other things to be getting on with.

Or, as Jackie Ashley put it in the Guardian yesterday, "Perhaps the biggest problem is that the politicians dreaming up these plans are different from the rest of us. After all, they are quite happy to spend 24 hours a day, seven days a week working at politics. The rest of the country have a life."

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
