Chanot style F hole placement?

[polkat]

What would be a good approach for F hole placement on Chanot style cornerless violin, where there are no corners to measure from? The body is a standard 14" Strat form without corners. Would it be best to just use a basic 195mm mensur and go from there?

Most of the `guitar,` shaped ones ive seen seem to have more or less elongated tapered (slightly from bottom upwards and round ended) width hole which seems to hog where the `c` bout area(if you can call it that) at an equally tapered distance from the edge.

Some ive seen have the bridge placement rather low down in relation to the F`s and others about centrally in relation to the centre of the f`s. But in most cases the bridge/stop length appears to be always in the centre of the instrument(midway from top to bottom). This is all from eye though and ive never measured them.

Hope this makes any sense!

Thanks for the replay. Yes, makes some sense. I plan to use a basic Strad F hole design. I was reading a paper by Thomas King about Cremonese F hole placement using the Golden Section of a line between the "pins" of the violin. This method doesn't require corners, but I'm confused by the term "pins." I have heard of using pins to align the tops and backs, but don't use them myself. Was this common on the older Cremonese instruments, and does anyone have an idea of where these pins were usually located?
