Wood • Adult • Level I: Woodworking • Wed (10/21/26 – 11/11/26) • $280 • MAIN
with Tim Gordon
Curious how to use milling machinery– table saw, chop saw, jointer, and plainer? This beginner-level class will focus primarily on milling: the fundamental process of measuring, cutting, and preparing wood for a project. Over the course of 4 weeks, you'll learn how to safely use several of our milling machines to cut and shape wood, as well as some of the basics of joinery (joining pieces of wood together), and shaping and finishing with hand tools. We'll walk you through the whole process of creating a simple but beautiful functional piece that you'll want to brag to all your friends about.
This class has no prerequisites and is open to beginners and seasoned woodworkers alike, but our Wood Studio has some safety basics before anyone is allowed to join in the fun (failure to meet these requirements will result in not being granted access to the equipment):
- Please come dressed in close-toed shoes, a shirt that can be tucked in and either short sleeves, or sleeves that can be rolled up past your elbows.
- No loose or dangling jewelry.
- If you have long hair, please have it securely tied back from your face.
- We will provide safety goggles and/or full face shields, ear protection, and face masks to cover nose and mouth, but if you have your own PPE you would prefer to use, please do!
