I’m placing the F-Holes on the Stainer model, to do so I first tried following the paper written by Alvin King “The Cremonese System for Positioning the F-Holes“.
His method includes Amati models, which should be similar to Stainer, but the layout did not work for the Stainer model.  Mostly due to the shortness of Stainer’s f-holes and the length of his top bout.

Failed Layout of F-Hole

In the end I set the f-holes based on The Strad poster measurements, a safe upper eye-width, and a comfortable notch location with respect to the stop location.
