Master Precision Glue-ups with Biscuit Joiner (Thu, April 23, 2026)

Thu, 23 Apr 2026 23:30:00 GMT

This hands-on workshop teaches you how to use a biscuit joiner to cut perfect oval slots for fast, repeatable, and hidden wood alignment.

Learn a clever joinery technique that uses oval "biscuits" that makes the glue-up process simple and precise. This is a great improvement to a plain edge-to-edge joint and simpler than dowels or Dominos. You will learn how to dial in the biscuit joiner for flush surfaces that require minimal sanding and offer a professional, gap-free finish. Whether your project requires a tabletop, shelf or panel, this class provides a technical foundation for efficient use of expensive wood.

Experience Level

Some experience using a table saw is required.

Skills You Will Learn

(1) We will learn why biscuits keep panels flush during glue-ups, (2) dive into referencing the machine fence versus the baseplate for repeatable slot depth and height, (3) and the safe execution of plunge cuts to ensure your joints stay exactly where you marked them. After the class, you will be able to tackle your next glue-up with confidence and get precise results.

What to Bring

Clothing suitable for the wood shop — close-toed shoes, no loose or dangling clothing or accessories
Eye and hearing protection (required) — dust masks and eye/ear protection are available to borrow, but bringing your own is recommended

This hands-on workshop teaches you how to use our INCRA I-Box jig on the table saw to create repeatable box or finger joints without gaps.

Learn the art of the classic box or finger joint—a technique prized for its mechanical strength and beauty. Unlike miter joints, finger joints showcase corners making them the perfect choice for your next project. By mastering the setup and execution of these joints, you’ll be able to create gap-free corners that are as beautiful as they are durable. Whether you're building a delicate jewelry box or robust shop storage, this class provides the technical foundation you need to make heirloom quality work.

Experience Level

Confident use of a table saw is required.

Skills You Will Learn

(1) We will learn why finger joints offer superior mechanical strength compared to other corner joints, (2) dive into joint spacing, (3) and practice safe vertical cuts to ensure perfectly flush corners every time. After the class, you will be able to produce gap-free finger joinery that adds a professional, custom look to any project.

What to Bring

Clothing suitable for the wood shop — close-toed shoes, no loose or dangling clothing or accessories
