Cutting Biscuit Slots in a Miter

Biscuit joinery is one of the most versatile, accessible, and affordable woodworking techniques available today. Whether you’re building cabinets, assembling furniture, or tackling custom woodworking projects, a biscuit joiner gives you strong, reliable alignment without requiring complex machinery or a huge shop footprint. But some biscuit‑slot situations are trickier than others — and cutting biscuit slots into a 45‑degree miter joint is one of the most challenging setups you’ll face. The workpiece isn’t stable, the fence has nothing solid to register against, and getting an accurate, safe cut can feel nearly impossible.

In this video, George demonstrates a clever, shop‑friendly technique that solves the problem. He starts by showing just how unstable a mitered board can be when you try to cut a biscuit slot directly. Then he reveals a smart setup that transforms two angled pieces into a rock‑solid 90‑degree surface — the kind of surface biscuit joiners excel at. The method is simple, repeatable, and perfect for anyone who wants clean, accurate miter joints without stress or guesswork.

Key Highlights from the Video:

- How to stabilize a 45‑degree miter for safe, accurate biscuit‑slot cutting
- Step‑by‑step setup for flawless alignment and repeatable results
- Perfectly matched biscuit slots on both mitered pieces using a single setup
- Ideal for cabinet construction, furniture building, and precision woodworking

If you've ever struggled with mitered biscuit joints, this technique will change the way you work. It’s fast, safe, and incredibly effective — exactly the kind of woodworking trick that elevates your craftsmanship. Give it a try on your next cabinet or furniture project.
