Having trouble deciding on the best wood clamp for your woodworking project? Every workshop has a collection of C-clamps and most people have a basic understanding of how they work. What many people fail to realize is that there are a wide variety of different types of woodworking clamps all with unique purposes and uses.

When you are just starting your wood shop or planning some DIY projects, you might be confused about all the options that are available. To help you make a better selection, here are some of the most common clamps and what they’re used for.

C-Clamp (G-Clamp)
C-Clamps tend to be inexpensive and are often used in woodworking projects. They are geared toward most general woodworking or even metalworking projects. They can be limited in uses due to the size restraints, but the deeper “C” shape does allow for some room to move things around.

C-clamps tend to lose torque over time but the fact that they are inexpensive makes up for that. Most people will own several sizes of C-clamps for a variety of projects.

Miter Clamp
When you need to hold two pieces together at a right angle, a miter clamp might be a good resource. The two clamping fixtures are set at a 90-degree angle. All you need to do is slide in the board, tighten the handles and the clamp will hold them together. Miter clamps are typically used for miter joints, picture frames and moldings.

How to use clamps

No matter what type of clamp you choose, there are some simple rules that will make the process easier for you.

  • Use scrap wood – Use a spare piece of wood to place between the jaws of the clamp and your work area. This will prevent damage to the piece you are working on.
  • Firm even pressure – The pressure from the clamp should be applied at right angles to the glue line. Failure to do this could result in slippage.
  • Clamp on tight – Once you’ve positioned the clamp, close the jaws until the clamp appears to be tight. If there is glue involved in the project, you will notice some squeeze around the joint. This is a good sign that the clamp is on tight enough.
  • Don’t overdo it! – While tightening the clamp is important, you don’t ever want to overtighten. The general purpose for the clamp is to apply uniform pressure between surfaces. Don’t use a clamp to force the surfaces to fit together. Moderate pressure should be all you need to complete the task.
  • Avoid surface damage – One handy way to keep C-clamps from marring surfaces is to apply milk caps as pads.
  • Extending clamps – When you need extra-long clamps, bolt bar clamps together. Drive out the retaining pins at the ends of two bar clamps. Then, drill two ¼-inch holes into the bars at the ends. Remove the movable jaw from one bar and reverse the movable jaw on the other clamp. Screw the bars together with ¼-inch machine screws plus nuts.


It is easy to see that no matter what project you are planning, one of the many different types of woodworking clamps should assist you. Take your time and choose the clamp you feel best fits your needs. Just remember, sometimes woodworking problems are based on trial and error. It may take a few different varieties before you find the one geared specifically toward your job.
