However, if this is the first action like this that you've encountered, I hope you didn't give the owner an estimate yet as to how much it would cost to correct the problem. The slow hammers could just be the tip of the iceberg! If high humidity is causing tight action centers on the hammer flanges, you can be sure that the problem has spread to the wippen flanges and jacks as well. You're going to have to check and probably treat every action center on the piano in order to get repetition back to where it sould be, or you could be facing repeated callbacks from the pianos owner. If you should find that the problem has spread to the jacks and wippen flanges as well, the Protek treatment may only give short-term relief if the humidity in the environment surrounding the piano remains high. So you probably should consider installing a Dampp-Chaser in this piano as well. If this is the first sluggish action that you've encountered, consider it a learn- experience. The NEXT time you encounter one, you'll be aware of the considerable amount of time that cam be involved in correcting the problem and hopefully charge accordingly. Have fun!
