Several months ago I aksed how to weaken an overly strong shift-spring on a model M. Before returning to the clients to try standing on it (one suggestion I recieved), I decided to give Steinway a call. Within minutes, David Kirkland faxed me an image of the factory tool used for adjusting spring tension. It is a steel bar appearing to be 1 1/4" high x 6" long with a 3/4" X 3/16" vertical slot about 3/8" from each end. (having trouble picturing this? imagine a short,steel, damper up-stop rail complete with screw-slots) The caption reads: factory tool, shift-spring tension adjuster,1/2" thick hardened steel. The tool provides leverage to adjust tension, without having to remove the spring, "terrific!" I was actually "tickled" just to know the factory considers the spring as an "adjustable" part. Anyhow, I wanted you folk to know about this tool, as well as the freindly and efficient service I received from Steinway today. "thanks David!" OF course, if all else fails, I am prepared (in my client's abscence)to stand on the spring. :>) BTW, many years ago, a friend who owns a cycle & ski shop asked me "do you know how we straighten a bent bicycle rim?" "With the bike upside-down, we rotate the rim, spot the bow, and whack it with a big mallet." He continued, "Do you know how we charge for straightening bent rims?" "FIVE BUCKS A WHACK!" And now you know! best regards, Mark Cramer, Brandon University
