Aside from the color and length of the keys, the levers at the end will be like this, with this shape

Since I had to temporarily stop construction due to a Taskin cembalo that needs to be finished quickly, in my free time I started sketching the design for the decorative paper that will cover the exposed spruce sides; here is the reason why.

The type of router bit I meant... that one must be an end mill, whereas I have always used straight bits like TUPIE, to be clear.

The geometric pattern is beautiful and will surely turn out well; will you do it monochrome or in color? Sorry for the inconsistency, but I am very busy during this period, damn me..

Eh, I also have little time during this period... I just repaired a small lever under my teacher, among other things...

I don't really know what kind of milling cutter it is, anyway, it looks almost like a drill bit and I can only understand it roughly haha

On paper, I haven't decided for sure; the small ones different from the grades will be in two colors, but I haven't decided which ones

It's been a while since I updated the thread, mainly because there is no news, but I'll show you how the harpsichord is progressing, which should be delivered by the end of the month, at most early June; once this is finished, I will resume work on the clavichord, and there are also a couple of spinets to do, but they are instruments significantly smaller than a Taskin and therefore it will be possible to work simultaneously on a spinet and on the clavichord.

Small brief news, today I finally managed to understand the key coupling of my clavichord; to understand it, I had to take the drawing of another German clavichord, but one made significantly better, and by looking at the position of the tangents, it became immediately clear and the calculations now work out perfectly.

Aside from the first low octave which only features B-Bb coupled, the two octaves above have 10 coupled keys per octave: C-C#, D Eb-E, F-F#, G-G#, A Bb-B.

The last octave is coupled differently again: C-C#, D Eb-E, F-F#, G-G#, A-Bb, B-C.

This is to save 34 strings and make 60 in two courses instead of 94.

Now I have to calculate the diameters of the strings to be used; it will surely all be yellow brass, I might have to use red brass on the basses, but I will only find out by doing the calculations.

Hi, you won't believe it but I'm back... lack of time (meaning the garden weeds that don't seem to stop etc.) also I no longer have mobile internet and so..

I see the beautiful photo... wow!! What a lovely place to play. Progress on the work? Set up other things?

As for me, I am having car trouble and tomorrow and Monday I have two concerts.. the clavichord is still completely stationary until we finish the harpsichord, but it's well underway now, it will be playing next week!

Why not, if I manage to go I will record something on the Taskin, there are many curious people

So, for now, today I recorded this; obviously the instrument is not finished yet, but these are the two 8', as for the 4' we are doing some small adjustments these days. The bar that regulates the key travel is not fixed yet, so doing trills and mordents is a bit of an undertaking; moreover, we discovered that the Taskin was certainly not strung at 392 but at 410-415 Hz, so the stringing is also still unstable having pulled it up by a semitone (at 392, as some of us were saying the Taskin should be, it cannot even be tuned).

All this to say that the recording is what it is

Well, by the 25th the harpsichord will be finished, so then I will get back to the clavichord and finish it

but the harpsichord sound, if I'm not mistaken, I've already uploaded it somewhere! It has been working for a while, there are just some small details left to finish: the studs around the brass levers, checking the springs of the jacks (he is trying to convince himself to do it more than anything, he doesn't feel like it ahahah) and he needs to fix the design of the stop levers a bit, then I think there is nothing else to do... he put in the lute stop this week, the only nuisance is that it doesn't hold the 415 Hz tuning well; it tends to stabilize at 108-410 (which would technically be the original pitch according to the curator of the Russell Collection in Edinburgh, where the original is located) oh yes, there's still a piece left to glue, more than anything because he can never decide whether to glue it or screw it (he would want to screw it, I would glue it) but in the end I think I won him over, he should have glued it last night...

in short, the final details need to be fixed and more lacquer and the final wax applied.

i repeat: I had perhaps uploaded a link with the Taskin recording right on this thread, provided I haven't deleted it

correction, yes, it is up there in the post with the photos of the harpsichord! I'm not sure if it still works, I've had problems with my phone (fried)

New updates from the clavichord: today I resumed work on the keyboard, leveled and flattened it, then I traced 4 lines with a small saw (purely aesthetic; in truth we were in doubt because normally there are 2...4 on larger ones, but this one is small; we even hypothesized that they might be small ebony blocks, but from the color of the pattern it doesn't seem so) having done this, I tapered all the corners of the keys except for the external ones of the first and last with a scraper, one key at a time.

For tomorrow there are some pieces to glue and probably the whole keyboard needed to be cut, certainly the first and last key.
