I thought I would save what I think is the best for last (well, almost last).
I built this in 2001 before I had a digital camera so I don’t have any construction pictures.
This was built from a set of plans I got a long time ago, and it took a while to get all the
supplies together to build it.
The case and legs are poplar. The sound board (surface below the strings) is spruce,
the bridges are beech and the jacks (the part the key press up to pluck the strings) are made from
swiss pear. The keys are made from basswood.
The curved side was laminated on a form I made.
Here you can see all the jacks lifted up. You have to do that to take the keyboard out.
The next three pictures show on of the hardest pieces to make. I think I spend the most time on it than anything else. It’s the curved bridge.
No matter what I tried I wouldn’t get that tight curve by steam bending. I ended up doing it in two pieces.
I steamed it as close as I could then cut off the end and glued another piece to it which I carved into shape.
The keyboard is probably the most complex part. Not really hard but just a lot of thinking and work.
To get everything to line up you start by gluing up a piece the width of the keyboard and marking a
diagonal line across the blank the keep them in order. Then it’s the bandsaw and coping saw to cut
them out. This leaves a bandsaw width space between the keys.
There is a lot more to it but this is the gist of it.
The jacks are made from swiss pear. It won’t warp no matter what you do to it.
In a harpsichord the strings are plucked versus struck like a piano. The felt silences the string when you let
up on the key.
Here you can also see the rear beech nut (the part with the tiny pins sticking out).
Here it is with the lid closed. You get a softer sound when it’s played closed
Here is my long term project. It’s a full size harpsichord that will have two keyboards, three strings for each key
and three sets of jacks. This one I couldn’t find plans for so it is being built from pictures in a lot of books.
I will take progress pictures from this point on and post it if I ever get it done.
