Whenever I glue up a frame and panel door, I want it to be dead-on square. That’s why I created the jig you see in the photo. It works great for gluing up assemblies, like doors, frames or drawers, quickly and accurately. A couple of clamps across the frame will hold it together until the glue dries. Since the fixed fences are perfectly square to each other, the assembly is virtually assured to be square as well.
As you can see in the drawing, the jig has two fixed fences. But the key is the adjustable fence that forces an assembly into the fixed fences and automatically squares it. To make the jig, I cut two pieces of plywood and glued them together for a base. The next step is to cut grooves and add T-tracks. Then attach two fixed fences along two edges of the jig, making sure they’re perfectly square to each other.
Finally, the adjustable fence is added. It’s held in place with flange bolts and star knobs. A couple coats of paste wax completes the jig and keeps glue from sticking to the base and fences. To use the jig, I fit my assembly against the two fixed fences and slide the adjustable fence up to meet it. Then you can tighten the star knobs.
