Homemade C-clamps


C-clamps are used for many different types of projects, from assembling furniture such as tables and chairs to holding planks in place to form the hull of a boat. But no matter how many you have, you always seem to run out just when you are almost done. But if you have the spare parts on hand, you can quickly jury-rig some homemade C-clamps to fill the gap. While they might not work for heavy loads, for most projects they should perform well.


  • Gather the material you will need, including wood (it can be some scraps you have lying around), screw bolts, nuts and a small screw-band clamp. Determine the size that you need for your C-clamp. You want to know both the width (gap between the arms of the "C") that you need as well as the depth (the distance from the ends of the "C" to the back).

Cutting the Pieces

  • Use a jigsaw to cut out C-shaped pieces of wood. The thicker these pieces are, the more strength your C-clamp will have. If you already have some wooden handles you are not using, you can use these. Use a drill to cut a hole at the end of one clamp arm. This is for a screw-threaded bolt; the hole needs to be just barely large enough to screw in the bolt.

Assembling the Clamp

  • Insert the bolt. Screw a wide nut over the end of the bolt. Securely tighten a screw-band clamp around the end of the other arm of the clamp. Make sure that the screw is positioned on the outside so that flat band can reinforce the clamp. Use your clamp by placing it over the object to be clamped and tightening the bolt. Don't over-tighten, or you might crack the wood.
