I designed and built the workshop myself for the express purpose of making guitars. It is a timber-frame construction,  fully protected from ground humidity, and under permanent hygrometric control.  All wood is stored in this controlled environment for several years before use to ensure stability, and conditions are strictly maintained at 40% – 45% relative humidity during the build period of each guitar. I build with hand-tools as much as possible, but some woodworking machines are essential both for efficiency and because they are simply better at certain tasks.
