The first thing to check is that the butt springs are doing their job. The butt spring pressure significantly affects the touch weight. If you strengthen the butt spring you increase the touch weight and if you strengthen it too much you increase the weight even more at the cost only of repetition. Many players will not notice the difference in repetition, and this difference can be reduced by also stretching the jack spings slightly, which will further add to the sense of weight in the touch. These changes are easily reversible and require no modification to the keys. I have a client, a very competent professional player, who very much likes and wants to hire a small grand I have, but she wants the touch heavier in order to give her fingers more work. I have no intention of removing or adding leads to the keys only to have to undo the work at the end of the hire, so I am fitting polyester cord loops under the keys just forward of the pilot boring and long phosphor bronze springs inserted into the front face of the backtouch rail will pull down on these loops to increase the touch weight. Adding weight to the hammer assembly is no way to increase touch weight, since it not only affects the tone but also increases the work required from the repetition spring, which can break as a result.
