Vibrational stiffness freq for ukulele?

[North]

Hi,

Does anyone has any data or suggestions about the vibrational stiffness f of a ukulele build?

Concert or tenor, but everything would be of interest.

I've used 150 with some luck at a concert uke. I derived the number by testing different values of f in my spread sheet, comparing the suggested thickness of the spread sheet to more typical thicknesses around - under the assumption of a 'normal' top stiffness. But as we know, wood varies quite a lot.

I am very interested in any data for Tenor Ukulele

Thanks for the link Trevor!
I am going to try f=140 on my next Tenor Ukuleles.
The last batch I did had a T(1,1)1 around 179 and a T(1,1)2 around 357
and don't sound bad at all.

Thanks, Trevor!! Lots of good info and sample numbers in that thread!
