It's ALL THINGS CONSIDERED from NPR West. I'm Arun Rath.

The Steinway piano company has a new owner. This fall, the investment firm Paulson & Co., led by billionaire John Paulson, spent about $500 million buying all of Steinway & Sons, the venerated piano maker. The deal includes a foundry in Springfield, Ohio. And you could say this is where the Steinway pianos are born in fire. NPR's Noah Adams has this story.

NOAH ADAMS, BYLINE: In New York City, at the Steinway showroom, you'll check the price on a Model D - that's the big concert grand - it's going to be $142,000. This very piano, gleaming and elegant, got its real start in flames and smoke and scrap metal 600 miles away in Springfield Ohio.

This is the O.S. Kelly foundry. And Kelly's been making Steinway's plates since 1938. The plate is the cast iron heart of a piano. It holds the steel wire strings with, the company says, 40,000 pounds of tension. It allows vibrations to arise in a concert hall as music.

The plates are an old design and so is the Kelly foundry. Even the dust in this dark, echoing space seems a century old. They call this part of the foundry operation the melt shop.

DAN HENSLEY: This right here is our furnace. See the spout?

ADAMS: Dan Hensley said: See the spout? Part of the furnace is called a tea pot. It will lift and tip over to pour the liquid metal. On this night, the melting started at 11:00. By midnight, the furnace is clanking and throwing off showers of sparks.

HENSLEY: We got 1,300 pounds of steel. Behind that goes 1,300 pounds of pig iron. And then we fill it the rest of the way up with what we call re-melt.

ADAMS: The world is re-melt. That means piano plates that didn't pass inspection just thrown back in. High overhead, a large electromagnet glides in to hover over the furnace hopper. Down below, a button is pushed to release the scrap metal.


ADAMS: Ryan Houseman is in charge of loading the furnace. The pouring operation is the work of two men, Ryan and Dan Hensley. Ryan Houseman has had other jobs in the factory, started in the melt shop a year ago.

RYAN HOUSEMAN: The first thing I noticed was all the dirt around here. And it was a little overwhelming, but, you know, I saw them pouring iron and I thought that was pretty neat.


ADAMS: At 1 a.m., the melt is ready to go. The iron flows into a large black ladle, which is suspended from a system of overhead beams. The two men guide the ladle out to the foundry floor where the plate molds are lined up.


ADAMS: The molds are chemically treated sand. It hardens quickly around a form. Take out the form, you leave a hollow space inside.


ADAMS: The ladle hovers over each mold in turn and tilted. A stream appears and enters though a hole left in the sand. The iron is over 2,000 degrees and incandescent, a luminous yellow-orange.


ADAMS: The two melt shop men, Ryan and Dan, take turns pouring. They are like dancers moving on top of the molds. They wear dark visors and flame-resistant shields over pants and boots. Dan Hensley has been pouring since 1987. He always wanted his wife to see what his job was like.

HENSLEY: And I brought her in here one night. See, we have to climb up on these molds, pushing and pulling on that ladle, that big one. And the next morning I got home, her first comment was, she said: I will never ever complain when you say you're tired.


HENSLEY: And I'm like, yeah.

ADAMS: Lunchtime is 2 a.m. In the first half of the night, 12 molds had been poured. On the day shift later, the rest of the foundry staff will take over all the prep work and the shipping. Now, for the melt crew, it's time to open lunch boxes in the break room and talk a bit about the job, and I ask about injuries. Ryan Houseman missed eight weeks work. He had to be airlifted to a burn center in Dayton. He'd been pouring iron, turned away, and there was a small spill.

HOUSEMAN: Apparently, it started running out and just a little drop went through the back of my pants, down into the bottom of my boot and burnt the bottom of my foot.

ADAMS: Dan Hensley, pouring since 1987, says he's had a few droplets, like BBs down his boot. Not all that bad, he says.

HENSLEY: That's the reason we wear slip-on boots so you can kick your boot off. If you have a tie up, it's an extra 20, 30 seconds trying to get your boot off.

ADAMS: Dan Hensley and Ryan Houseman at the O.S. Kelly foundry that Steinway owns in Springfield, Ohio. These two men pour the cast iron plates for all of the Steinway pianos. That is 4,000 plates a year. Noah Adams, NPR News.
