This beginner-friendly class introduces students to the art of creating unique wooden boxes inspired by traditional eastern techniques. Through hands-on learning, students will explore how to design and assemble intricate sliding mechanisms that unlock hidden compartments.

What You’ll Learn in a 3-4 hour class:

Box Construction Basics: Build a sturdy box-in-box framework as the foundation for your secret box.

Sliding Mechanisms: Create secret sliding dovetail joints and moving parts that make the box a puzzle to open.

Precision Hand Tool Work: Master the use of a pull saw, hand plane, and other tools to craft fine details with accuracy.

How the full day class Works:

The workshop begins with a collaborative demo followed by a warm-up where each student constructs parts of a simple box to understand the core techniques. Once the fundamentals are covered, students are encouraged to unleash their creativity and design their own secret, to be solved to open the box.

Along the way, the instructor will demonstrate advanced wooden mechanisms and decorative methods to inspire your designs. You’ll leave with a beautifully crafted puzzle box and the skills to continue exploring on your own.

Your instructor will provide the following:

• Baltic, Birch, Plywood, Basswood, Cherry, and Walnut
• A custom saw guide
