Set, clamp, and go!
With these corner clamps, it’s as easy as that.
Just set the thickness of the sheets you want to connect, place the sheets in the right position, clamp, and you can connect them together.
You don’t have to hold the sheets anymore, and the connection is always perfect.
When the connection is made, you can remove the clamps in a few seconds.
Building these Corner clamps step by step
Now that we have gone through the list of what we all need for this project, I will explain step by step how I made these corner clamps.
Collect your materials and find the best wood.
Let’s build this clamp!
Step 1 | Preparation
Saw all parts as indicated on the plans that you can download in this blog.
To cut the pieces safely and quickly I used my crosscut sled. Be sure to watch the video of how I made my crosscut sled to get some inspiration.
Step 2 | Making a slot
To keep the wedges in place I made a slot in the base of the corner clamps.
To make the slot, adjust the height of the saw blade to the depth you want to make the slot.
With the crosscut sled, you can easily slide the base plate over the saw blade to make a flat slot.
Afterward, you can finish the slot with the chisel and sandpaper if necessary.
Step 3 | Placing the center bolt
To be able to move the adjustable part up and down and to fix it, you can use a bolt that is fixed on the bottom plate.
Later in this blog, I will show you how to make the button to fix the movable part when adjusting the clamp.
Drill a hole at the specified distance as on the plans. Use a drill with a diameter equal to the diameter of the bolt.
After drilling, make the hole at the bottom of the plate larger so that the head of the bolt fits perfectly.
Do this by marking the head of the bolt with a pencil and carefully chisel out the hole.
Step 4 | Adjustable part
Now you can make the adjustable part of this clamp.
First, drill the holes at the indicated points as shown on the plan.
After drilling the holes, cut the slot with the jigsaw by cutting from one drill hole to the other.
After cutting, trim the slot with a file so that it has the same width everywhere.
Step 5 | Wedges
Now make the wedges.
I made these wedges by combining my miter saw with my crosscut sled. That way I didn’t have to reset the angle of the miter saw all the time.
Check the plans for the correct size of the wedges.
You can now use the wedges as pairs on the clamp. The wedge that is flush with the outer edge of the corner clamps needs to be secured with wood glue and brad nails.
If you do not have a nailgun, you can use regular nails for this.
Look carefully in which direction you should place the wedges. If these are not placed correctly, you may experience difficulties when working with the corner clamps.
Step 6 | Securing the wedges
To prevent the wedges from falling out of the corner clamps, especially when you use the corner clamps upside down, you will need to attach a cover plate above the wedges.
For this, you can use 6mm thick plywood. Secure this plywood with wood glue and brad nails.

Step 7 | Making a knob
To fix the adjustable plate when setting it up, you can use a regular nut or a knob that you can buy ready-made.
Because I built a star button jig on my drill press a while ago, I made this knob myself.
To be able to screw the knob onto the bolt, I placed a T-nut in the knob by gently pressing it into the knob with the vice.
Step 8 | Assembling the Corner clamps
The clamp is now ready.
All you have to do is slide the wedges into place and turn the knob on the bolt.
To make all edges nicely flush, I placed the clamp on the crosscut sled and slid it along the saw blade. That way I got a nicely finished clamp.
How to use these Corner clamps
Working with these corner clamps is super easy.
Set the adjustable piece according to the thickness of the wood. Because I usually use 18mm wood I marked a line at this size.
Place the wooden boards you want to connect in the clamp.
Clamp the boards by tightening the wedges.
It’s difficult to picture a workplace without clamps.
You will need clamps for practically every job you do. Because clamps are expensive, it is advised to purchase only the clamps that you require.
