How to Clamp a Picture Frame

Before we proceed to the list of best picture clamps, let me give you a clear explanation of how these clams work.

The main goal of a clamp is holding an object firmly, and yes, its goal is that simple. You can either use a clamp to hold two or more pieces together or clamp an object steady to your workbench. The clamp doesn’t let the object stroll on the surface so that you can begin further working on that object.

Some clamps have only one jaw, and some have two jaws. One-jawed clamps are used to hold an object in a base. If there are two jaws, both of the jaws work together to hold an object.

You can control the jaws but how you can control them depends on the type of the clamps and the mechanism used to build the clamps. Clamps can have strings, triggers, or levers that can be used to adjust the jaws. You will also find screws in some clams that are being used as part of the adjusting mechanism. Screwing in will make the clamp jaws fasten around the workpiece and apply pressure. Screwing out will make the jaws release the workpiece.

Joints Where You Can Use Angle Clamps

You can use angle clamps not only for holding picture frame joints but also for some other joints. Let’s have a look at what joints are suitable for angle clamps.

Miter Joints

Also called a 90-degree joint, the miter joint is the typical joint of a picture frame. A miter joint is formed by joining two wood pieces where the joining ends of the two pieces are cut at a 45-degree angle. Joined pieces produce a corner where the inside angle is 90-degree.

Usually, glue is used for attaching two pieces. If you are not aware, a slight shifting or shaking may leave the joints uneven and reduce the glue’s effectiveness. An angle clamp will not let these disturbances happen. You can also change the jaws according to the thickness of the pieces you are going to join.

As angle clamps suit perfectly with miter joints and are widely used for the clamping picture frame, they are also recognized as the picture frame clamps.

Butt Joints

Among other joints, the butt joint is the simplest and weakest joint available out there. You are not required to cut the edges of the pieces; instead, join the squared-off edges into the edge to face position. That way, the joined pieces will be attached perpendicular.

The weakness of a butt joint comes from the absence of reinforcement. A butt joint gives its total reliance upon glue to join two pieces together.

Angle clamps work great in holding butt joints as you can place the jaws to fit two wood pieces at the right angle. As in butt joints, glue makes the joining area slippery, and one piece can slip on the surface of another piece. An angle clamp doesn’t let this happen.

T Joints

T joints are when a piece is joined perpendicularly, constructing a ‘T’ or somewhat ‘T’ like shape. In T Joints, pieces are joined together using glues or by following mortise and tenon joint techniques.

In mortise and tenon joints, you have to make a square or rectangular hole in a piece where the tenon of another piece can sit tight. After joining, you have to use adhesive to make the joint stronger.

Whether the T joint is made using the mortise and tenon joint or just by gluing pieces together. An angle clamp can hold and make accurate T-shaped T joints.

Frequently Asked Question Answered

1. How Do You Clamp a Large Frame?

To clamp a large frame, you will need a corner clamp with a strap long enough to wrap around that frame. You can also use individual clamping pieces to hold the mitered corners. In that case, you will need 4 corner clamps.

2. What is a Picture Frame Clamp Used for?

The main objective of a frame clamp is holding the joint of two woodblocks while the glue dries, making a solid and perfect angled joint. Frame clamps are not only used for clamping picture frames. They are also used for clamping objects where assembling pieces is necessary.

3. Is it Possible to Make a Picture Frame Without Corner Clamps?

For this, I will say nothing is impossible. But it will be a difficult task to make the frame joints strong 90-degree angled. You can make a frame clamp jig to hold the joints firmly. Both will give you enough support in making a nice and clean picture frame, whether you use a corner clamp or clamp jig.
