Sort of a craft, but I stumbled into getting a harpsichord from a friend recently...
I didn't make it, but it was in pretty rough shape (missing some parts, clearly mice lived inside for a while), and I've started cleaning and overhauling it.
Couple dozen hours in now, or so, and I think it's basically cleaned (working on the smell....) I'll be refelting everything, probably cutting down the keyboard tray so I can make it a transposing keyboard, designing and 3d printing a full set of jacks (the bit that makes the key pluck the string), building a jackrail, adding a lid stick, and restringing, voicing, and tuning the whole thing. Oh and it needs legs.
Quite a beast of a project, especially given my relative lack of knowledge of harpsichords, but the mechanism is pretty straight forward and the materials aren't too expensive, so it will be a good project, I think.
I'm a bottle of hydrogen peroxide, a cup of vinegar, and two boxes of baking soda deep in the cleaning and de-stinking. The first replacement felts arrived today, but I've got to get some more sizes and order the strings in the next few days. Since there's some mouse related debris under the soundboard and no way to get at it, I'll be taking a large holesaw to the bottom, cleaning inside and checking it out, then closing it back up with a cover. Hopefully that will tell me about the soundboard construction so I know if my stringing schedule (which strings of what material/size go where) will be ok for the tension loading on the soundboard.
