Gluing on new Damper Lifter Felt. The masking tape prevents the end of the Felt from being glued to the key. This is so that shims can be added (if needed) to adjust the height of an individual damper.
Using a straight edge, the height of each white key is checked. If it is too low, a paper punching is placed on the front of the key. Then the punching will be placed under the felt punching that is under the fulcrum of the key to raise it to the correct level.
The action stack is then replaced onto the keyboard, and the action is rgulated. In this picture, the let-off is being adjusted. The let-off is the point at which the hammer stops rising and “Lets off”. Too soon, and the power is diminished. Too late, and the hammer will “Block” against the string, stopped it from ringing.
Starting the re-stringing process. The green tape on the plate holds down the new Anchor Pin Punchings (little felt washers that protect the plate where the string is fastened at its fixed end.) and the Duplex Bars (Brass bars that raise the strings off the plate to the correct level – see below) in place.
All done for the day. (Compare the above picture with the original!)

This step is especially important with the Bass Hammers, because they are glued at an angle. If these tails are not sanded flush, every time the hammer is used, it’s jarred a little to the side because of its shape.
Working ahead of me is Grayson, who is coating each bridge pin hole with a mixture of hot water and fish glue. This will soak into the hole, expand the wood, and then the glue will freeze the grains into their expansion. The pins are tapped in and effectively “glued”, however, the glue is not holding the pin – it’s holding the wood which is holding the pin.
The hammers, drilled, and ready to be glued on to the shanks.
