Have you ever struggled with assembling a cabinet, drawer, or box, only to have the corners slip out of alignment because the glue is slippery? Or perhaps you’ve spent hours trying to hide unsightly holes from stop cuts in your woodworking projects? If so, this article is for you. Today, we’re diving into a brilliant woodworking secret from Stumpy Nubs (James Hamilton), a Canadian carpenter with decades of experience. This secret will revolutionize how you approach woodworking projects, making them easier, faster, and more professional-looking. Get ready to discover the “Mysterious Hidden Groove Joint.”

The Problem with Traditional Joints

Before we get into the solution, let’s talk about the problem. When building cabinets, drawers, or boxes, one of the most common joints used is the locking rabbet joint (sometimes called a tongue and dado joint or drawer joint). This joint is great because it self-aligns during assembly, making it easier to clamp everything together without pieces sliding out of place. It also adds mechanical strength, preventing the front of a drawer from being pulled off over time.

However, there’s a catch. When you cut grooves for the bottom or back panel, you’re usually left with visible holes on the outside of the box. These holes need to be plugged or hidden, which can be time-consuming and frustrating. Wouldn’t it be amazing if you could create these grooves without the holes? Well, you can, and it’s simpler than you think.

The Secret: The Mysterious Hidden Groove Joint

In his video, Stumpy Nubs introduces a game-changing technique he calls the “Mysterious Hidden Groove Joint.” This method allows you to create grooves for panels without any visible holes, eliminating the need for stop cuts or complicated setups. The result? Cleaner, more professional-looking projects that are easier to assemble.

Here’s how it works:

Step 1: Setting Up Your Router Table

To create this joint, you’ll need a router table and a 1/4-inch straight bit. Stumpy Nubs demonstrates this technique with a router table, but you could also use a dado set on a table saw if you have one.

Start by attaching a scrap of wood to your router fence to create an auxiliary face. This prevents your fence from being damaged by the bit. Place the scrap about 1/8 inch above the table to allow sawdust to escape. Set the bit height to 1/2 inch above the table (adjust based on your material thickness).

Step 2: Cutting the Dadoes

For this example, let’s say you’re building a drawer. You’ll have two side pieces and two front/back pieces. Set your fence so the cutter is flush with the outer face of one of the front or back pieces. Use these settings to cut dadoes across both ends of each side piece. Because the sides are narrow, use a push block and a scrap of wood to keep the pieces perpendicular to the fence.

Step 3: Creating the Locking Rabbet Joint

Lower the bit to 1/4 inch above the table. Take a couple of passes to nibble away the material between the dado and the ends of the side pieces. This creates half of the locking rabbet joint. To create the other half, move the fence forward until the back of the bit barely skims its surface. Use this setting to cut rabbets on both ends of the front/back or top/bottom pieces. The tongue you create should fit snugly into the dado on the side pieces.

Step 4: Cutting the Hidden Grooves

Now for the magic! Raise the bit no higher than the thickness of the tongue you just created (about 1/4 inch for 3/4-inch stock). Move the fence back about 1/4 inch from the bit. Use these settings to cut grooves along the edges of all your workpieces. Make sure you orient the pieces correctly—this is crucial for the hidden groove to work.

And just like that, you’ve created a drawer (or cabinet or box) with grooves that are completely hidden. No unsightly holes, no complicated stop cuts—just clean, professional results.

Why This Method is a Game-Changer

This technique is incredibly versatile. Whether you’re making a small drawer, a full-size kitchen cabinet, or any other box, the Mysterious Hidden Groove Joint makes assembly a breeze. It’s also incredibly strong, rivaling the durability of more complex joints like dovetails but without the steep learning curve.

But wait, there’s more! Stumpy Nubs also shares a quick tip on another woodworking game-changer: 3M Cubitron II Sandpaper. This revolutionary sandpaper uses ceramic pyramids instead of traditional grit, slicing through wood fibers rather than plowing through them. The result? It works faster, stays cooler, and lasts up to six times longer than regular sandpaper. Once you try it, you’ll never go back to the cheap stuff.
