This is a theoretical explanation of only a few important physical properties of wood. Furthermore it […]

Cheval

A cheval is a form of wood replacement. Often, due to a bow frog’s small size, an entire section of wood has to be replaced with new wood to reinforce the structure and to supplement missing wood. Traditionally, a cheval is performed by planing away original material and replacing it with new wood. A rounded cheval maximizes the surface area […]

Raising the Projection

This is a guide to a common adjustment, especially in times when instruments experience higher than average humidity.
