The Legacy Perspective
A well-maintained shop is built one small habit at a time. These inspections protect your equipment, improve reliability, and strengthen your craftsmanship. The goal is not simply to complete a checklist, but to make thoughtful care part of your woodworking routine.
Legacy Principle
The machine contributes capability.
The operator contributes judgment.
Together they achieve craftsmanship.
