Installing the Liners

This photo shows the necessary holes being drilled into the keyboard blank before it is cut apart. This is most easily done on the drill press if the drill press's throat is deep enough to reach the pin holes in the center of the blank. If not, the holes can be drilled by hand with an electric drill and a small wooden guide to keep the drill bit perpendicular to the blank. While it's a little difficult to see in this picture, the keyboard is actually sitting on, and attached to, the keyframe. By doing this, the holes in the keyboard and the holes in the keyframe are guaranteed to line up. If a hole is drilled slightly out of position on the keyboard blank, the corresponding hole in the keyframe will be slightly out of position as well and the key will still function correctly. Once the keyboard/keyframe is removed from the drill press and the pins are driven into the keyframe, any pins that are not perpendicular can be tapped with a small hammer and a wooden block until they are 90 degrees to the wood they're inserted into.
