People who make musical instruments know they have to start with a good piece of wood. Some guitar makers are worried that the woods they need for their instruments are becoming too rare. Tamara Keith has the story of how guitar makers are working with a group that fights to protect trees:

(sound of a factory)

There are people all over the Martin Guitar plant in Nazareth, Pennsylvania, doing fine detailed work. One man is chiseling out tiny pieces of wood to make the neck and the body of a guitar fit perfectly.

(sound of sanding)

Dick Boak does artist relations for Martin.

“So this is a D-35, this is what Johnny Cash played.”

He says this guitar’s deep resonant sound is all about what it’s made of. It’s a who’s who of rare and exotic species.

“Rosewood from East India, spruce from the Pacific Northwest, and mahogony probably from Peru or Bolivia. Those would be kind of the traditional woods for a guitar.”

Boak says logging is wiping out old growth forests where these types of woods are found.

“We would like it if every single supplier that we used was working in a sustainable fashion because that would ensure that our future as a guitar maker would be you know intact.”

So Martin Guitar has teamed up with the environmental group, Greenpeace.

Scott Paul is the group’s Forest Campaign Director and he’s super interested in the Sitka Spruce used in the Johnny Cash style guitar. We’re talking at the group’s office in Washington, DC. And he shows me where the spruce is used.

“This part on the top. This here is the soundboard. This is the species that really projects the sound.”

That Sitka Spruce comes from South East Alaska. Paul has been crusading to save the forests there for some time. He says Sitka Spruce has been logged as if there were no end in sight. Most of it is used for low-end construction materials. But when he found out the wood was used by the world’s leading instrument makers – he approached them.

“It was a very interesting meeting where you had the CEO of Gibson, and the CEO of Martin and Taylor and Fender all in the same room.”

The competitors said they were concerned about logging practices too. And the told Paul they’d work together on the issue.

“Let’s all go to Alaska and start talking to the logging companies that are providing you this product and figure out if we can do it better.”

So they did. This new Musicwood Coalition went to the Sealaska Corporation, which logs Sitka Spruce. And they’re now working with the company to save old growth trees for really valuable things like guitars.

Musical instrument companies are a very small part of the demand for old-growth wood. Paul says its less than 1%. But they can be very influential.

“They need the wood. They’re not the driving force. But their profile, and to be honest, their sex appeal is perfect. Not everyone likes Greenpeace, but red state, blue state, everyone loves guitars.”

(sound of guitar being tuned)

Dick Boak is tuning a guitar that’s just about ready to leave the Martin factory.

“Everybody has a song they use to tune.”

This guitar is part of Martin’s sustainable woods series. The hope is that someday all Martin guitars – and those of Gibson, Fender and Taylor too – will be made from trees grown and harvested in a way that makes sure the wood will be around for the long haul.

Rethinking Window Replacement

Each winter presents some homeowners with a choice: whether to replace old,
wooden windows with modern, energy-efficient ones before cold winds blow

Each winter presents some homeowners with a choice: whether to replace old,
wooden windows with modern, energy-efficient ones before cold winds blow
again. Each year, more homeowners choose the replacement windows, often made from vinyl or aluminum. Shawn Allee found some historical preservationists want homeowners to think twice about that:

If you think century-old windows have to be rickety and leaky, Jack
Spicer would like you to come to his place.

He’s eager to show off windows on his Chicago two-flat, built in 1908.

“So, here’s an example of the way an old-fashioned wood window
looks from the outside a hundred years later. These windows are
longer-lasting and obviously better looking than any replacement window you
can find.”

It’s no surprise Spicer makes this pitch.
He’s with a group called Preservation Chicago, and he’s on a campaign
to save wood-frame windows from the onslaught of vinyl and aluminum-framed
replacements.

Spicer’s losing ground, even in his own neighborhood.

“This apartment building replaced their windows. The next building
replaced all their windows. If you look across the street at this huge
courtyard building, there’re about 48 units in there. Those windows were
fine, and those windows are now trashed. They went into a dumpster and are
now in a landfill somewhere.”

But if old wood-framed windows are so great, why do so many US homeowners
replace them?

“Somebody told them it would save them money if you put in brand-new
replacement windows. Everybody’s taught that – you read about it, you
see the ads. All the replacement window (companies) tell you, if you’re
American and you love your children, you’ll replace your windows. Well,
we’re getting over that now, I hope.”

Spicer insists replacing your windows is not an environmental slam dunk.

He says if old wood-frame windows are properly sealed and have storm
windows, they’ll hold heat almost as well as replacements.

I ask Spicer for numbers on this, and he sends me to Mike Jackson, with
Illinois’ Historic Preservation Agency.

“Several years ago, Vermont as a state did a study and they looked
at repairing windows, adding storm windows, replacing windows, and what it
really came down to was, how leaky are your windows? If they were
reasonably tight, there wasn’t a lot of savings to replacing your windows
at all.”

Jackson says a new furnace or insulation are better pay-offs, and
replacement windows often last just a few decades.

“We’re throwing away items that lasted for a hundred years with
simple technologies and replacing them with more complex things with
shorter life spans. In our line, the reason they call them replacement
windows is because you have to keep replacing them.”

Well, people in the replacement window industry don’t take kindly to
this.

One rep told me the short life span of replacement windows is overblown –
high quality ones last longer.
And he told me, if energy prices rise in the future, replacement windows
become more competitive.

So, is it worth replacing old, wooden windows?

“There’re many factors and that’s why it’s, in our opinion,
not so clear-cut.”

Christian Kohler studies window technology at the Lawrence-Berkeley
National Laboratory.

He says replacement windows are better on energy, but it could take decades
to get a good payback and by that time, you might need to replace them
again.

Anyway, Kohler says there’s an alternative.

If your wood windows are in good condition, you can add storm windows that
have what’s called a “low – E” coating.
The coating helps retain heat.

“It’s applied to glass and it’s virtually invisible. It
doesn’t have a color or anything.”

Kohler says if preservationists want to keep wood windows around on account
of their looks or long-term value, it still makes sense to crack down on
leaks and get good storm windows.

It doesn’t make sense to waste energy on account of beauty when you
don’t have to.

Major Dock Corrosion Stumps Officials

Corrosion is eating away at the steel walls that hold
one of the Great Lakes’ busy harbors together. The
corrosion is unlike anything known to be happening in
any other Great Lakes port. But other port officials
are being encouraged to take a closer look at their own
underwater steel. The Great Lakes Radio Consortium’s
Bob Kelleher reports:


Some kind of corrosion is eating away at the Duluth
Seaway port’s docks. The docks are those long
earth-filled metal rectangles where ships from around
the world tie up to load and unload. Those docks are
lined with sheets of steel, and the steel is rusting
away. Jim Sharrow is the Duluth
Seaway Port Authorities Facilities Manager.


“It’s corroding quickly – much faster than people expect
in fresh water. And our main concern is that we’ll lose
the integrity and the strength of the dock long before
expected, and have to do steel replacement at $1,500 or
more per lineal foot, much earlier than ever would have
been expected.”


Corrosion should be a slow process in Duluth’s cold
fresh water. But, Sharrow says, there’s evidence it’s
been happening remarkably quickly for about thirty years.


“What we seem to see here is corrosion that started in
the mid 1970s. We have steel that’s 100 years olds
that’s about as similarly corroded to steel that is 25
to 30 years old.”


It’s a big problem. There’s about thirteen miles of
steel walls lining docks in the harbor that serves
Duluth, Minnesota and Superior, Wisconsin. There’s half
again as many feet of wooden docks, held together with
steel pins. There’s corrosion on the legs of highway
bridges and the giant
steel ore docks that ship millions of tons of taconite
– a type of iron shipped to steel mills in Gary,
Indiana and Cleveland, Ohio.


“We characterize this as a 100-million dollar problem in
the harbor. It’s a huge problem, and what is so odd
about this is that we only see it happening in the
navigational area of the Duluth-Superior Harbor.”


The harbor links the St Louis River with Lake Superior.
Go a few miles up the river and there’s little corrosion
. So it doesn’t seem like the problem’s there. But, back
in the harbor, at the current rate of corrosion, Sharrow
says, the steel will fail quickly.


“I figure that in about 10 years at the current rate,
we will have to start replacing steel.”


“Particularly marginal operators could decide rather
than repair their docks it would be better for them to
go out of business, and we’re hoping that that isn’t
the case here.”


While the cause is a mystery, there’s no shortage of
theories. It could have something to do with stray
electrical voltage; water acidity; or the kinds of
steel manufactured in recent years. Chad Scott
discovered the corrosion in the late 1990’s. He’s an
engineer and a diver. Scott suspects
a micro-biological connection. He says there might be
something growing in small round pits that form on the
steel.


“We cleaned up the water. That’s the main thing –
that’s one of the main changes that’s happened since
the 70s, is we’ve cleaned up our water. We’ve cleaned
up our harbor, which is a good thing. But, when we
cleaned things up we also induced more dissolved oxygen
and more sunlight can penetrate the water, which tends
to usually promote more growth – more marine
microbiology growth.”


A team of experts met in Duluth in September to share
ideas. They came from the U.S. Navy, The Army Corp of
Engineers, and Ohio State University. And they agreed
there’s something odd going on – possibly related to
microbes or water chemistry. They also recommend that
other Great Lakes ports take a closer look at their
underwater steel. Scott says they at least helped
narrow the focus.


“We have a large laundry list right now. We want to
narrow that down and try to decide what is the real
cause of this corrosion. And these experts, hopefully,
will be able to get us going on the right direction,
so we can start doing testing that will identify the
problem.”


With the experts recommendations in hand, port
officials are now planning a formal study. If they
do figure out the cause, then they’ve got to figure
out how to prevent it. They’re in a race with
something, and right now they don’t even know with
what.
