Flat Surface Jig
July 5, 2024
Using a flat surface for glue-ups is essential for achieving strong, stable, and visually appealing woodworking projects. It helps in maintaining proper alignment, preventing warping, and ensuring a smooth and professional finish. The problem is finding a surface that’s not only flat but that makes clamping easy. With this jig, I think I found that kind of solution for narrower glue ups.

Step by step instructions
2. Creating the tongue
The truth is, we’ll need to have something that will fit inside of the vise. But that leaves a small void on the surface that can’t be clamped. I made the tongue with gaps in it so that I could use clamps within the center of the jig. This is up to you, but you’ll need a jig saw or a hand saw to do it.
Another option is to use a narrower tongue…but obviously not too narrow as you’ll need to support both the jig and the material you’re clamping…and the heavy clamps.
4. Leveling the surface
Now we’ll level the surface with a jointer. If you don’t have a jointer but have a hand plane (and don’t mind doing a lot of sharpening of that blade), feel free to use that instead. You’ll want to use a block plane if you go this route.
