Thanks for the advice on the tool. What I'm still looking for is someone who has experience jumping on the spring. Or is it better not to do that.

Since then I bought a couple of replacements and will put one in next time I see the piano. Here's is a couple of pictures that Kent Webb from Steinway sent me of the factory tool for this purpose. I put the pictures up on my website: http://pianova.net/media2/shiftspringtool.jpg http://pianova.net/media2/shiftspringtooldetail.jpg Ryan Sowers On Thu, Aug 16, 2012 at 5:00 AM, Tom Driscoll <tomtuner at verizon.net> wrote: Wim, I weakened a S and S return spring on a newish model B with a very sophisticated tool. Placing the spring on a piece of scrap wood on the clients garage floor I whacked it flatter with a big ass hammer. Two whacks --- eight years ago and all is still well.

I don't remember what it looks like, but it bends the steel. I wonder if anyone has ever tried to stand on the spring to do the same thing? Either stand on each end of the spring, or turn it around and stand in the middle. Hey, I weigh 240 pounds. Isn't that enough to bend the spring?
