    A bit late, I somehow missed some replies in this interesting thread. We derailed a bit as OP asked about tuning strategies and thicknesses of bars. I can only relate to what I do and what I think folks at Gibson did on Loars. I believe they just carved them to numbers from succesful prototype(s). There is just too little variation to warrant any tuning strategy (that would result in variations in heights of bars) and hypothesis of just target thickness seems to be too strong.
    I managed to dig out some of my old files that I probably never posted in the thread about Loar bars so I post them here, someone may be interested. These are two Loars of the first batches... Both have the same position and size of bars, their shape is slightly different from later Loars, the comparison drawing is mid 23 Loar and seems to be consistent with most april '23 through '24 Loars.

    To answer Roger's question I add a link to panel presentation of "Strad 3D" which shows direction to where the modern violin making is going (this is quite old from 2010 or so). Hutchins was a pioneer in scientific, theoretical study and measurements of vibrations of plates etc. but that didn't prove to be useful in practical work of the makers. Now they concentrate on study of modal analysis of whole violins and various much more sophisticated methods or combination thereof. Some of the recent award winners for tone are from ranks of followers of the most recent research.
    here is link to the article: https://www.reghviolins.com/publicat...pp.187-230.pdf
