This was my first cradle, I designed it so that it can fit both violin and violas of varying lengths. The cradle is intended to clamp into a vice. This style of cradle is useful for hollowing, neck mortise work and violin setup. However, it’s limited in the positions it can be used in, making the rotating purfling fluting jig more useful for some tasks.
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.
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.
