Here are a couple keyboard details.
This was the last clavichord where I glued on the pivot restraints on top. Zuckerman was doing it this way in the 70's and everybody else was using felt-lined holes ( as in a piano ), which, while quiet, makes for a sluggish action in a light key. The "proper" method is simply to cut a VERY thin mortise/slot in the top of the key with just a drill hole on the bottom of the key.
