I have an antique office chair, all refinished. But I can't find a replacement spring for the rocker mechanism. It is very simple, just an extension spring about 5 inches long and 1 1/4 inch in diameter. At least that is the one I have in there now. But it isn't nearly heavy enough. When you start to tip back it goes all the way with just a little force. I have looked and looked and can't find anything any heavier. Does any body know where I can find something like that?
Thanks, Bill
