[CAUT] scaling a Tyre harpsichord?

Looks pretty familiar.  Does that stringing schedule I sent bear any resemblance to what you've found?

Fred et,al.



I'm very much appreciating all the input.
 Here are some photos of said beast.  Do any of you see anything
funny about it?  If you want some more photos, I'm literally 50' from
it as I sit.



Thanks

Paul

I just ask because, first, been there, done that (tuned
to 440 not knowing it was built to 415); and second, Tyre would have a
well-scaled instrument, unlikely to break strings more than occasionally.
Changing the gauges isn't likely to solve the problem. But checking some
lengths and scaling is a good starting point, to see how it stacks up.
There isn't a whole lot of variation, except when you come to how much
the instrument is foreshortened, and so where the brass starts and how
thick it gets. That is, the high treble is pretty well all in the same
ball park, for any instrument. Changing gauges will change tension, and
raising gauges could cause structural issues (and change the timbre). But,
as a very long-winded thread a while back demonstrated/illuminated, the
notion that thinner wire is less likely to break for a given length and
pitch is not very accurate. If there are differences, they are small and
unpredictable.
