What is a bar clamp?
A clamping device consisting of a long bar with adjustable clamping jaws; used in carpentry.
A bar clamp is a versatile tool that can be used to work with both wood and metal.
Its main job is to hold pieces of wood or metal in place so that they can be permanently joined together.
Features of Bar Clamps
A bar clamp is usually made up of a long metal bar with two clamping jaws that can be moved.
The steel or aluminum bar is strong enough to hold large and heavy pieces of work without breaking.
Because the bar is long, it can hold long or wide pieces of work in its jaws.
This makes it useful for a wide range of tasks.
The Surprising Benefits of Using Bar Clamps in Your Woodworking Projects
Still hard to understand? Let me change the point of view a bit:
Are you sick and tired of your woodworking projects falling apart when you touch them? Do you like the frustration you feel when you realize your project has changed in the middle of building it?
Well, we know exactly what to do: just do not use the bar clamp at all! Who needs a reliable, sturdy, and versatile clamping tool when you can just wing it and hope for the best?
Even if your project does not turn out exactly how you planned and falls apart as soon as you move it, at least you will not have to use a bar clamp, right? ... Right?
Okay, that was just a joke made to look like a TV ad.
Now let's go back to the explanation.
Introduction to Bar Clamps
Bar clamps are useful tools that can be used for both woodworking and metalworking.
They hold pieces of wood or metal in place so they can be permanently joined together.
This article will talk about the different kinds of bar clamps you can buy, what they are used for, and what other kinds of clamps are out there.
Types of Bar Clamps
The most common type of bar clamp has a long, thin bar and two small jaws.
It is called a "sash clamp.
Both jaws can be moved, but one is attached to the bar with a screw while the other can slide along the bar.
Quick-release Bar Clamp
Quick-release bar clamps have a trigger that lets you make changes quickly and easily.
Pipe clamps are different from other kinds because the bars on them are round instead of flat or square.
A T-bar clamp is like a sash clamp, but it has a bar that looks like the letter "T" when seen from the end.
The top part of the bar is wide and flat, which gives it more support and makes it more rigid so it can hold bigger things like wooden doors or frames.
Sizes of Bar Clamps
Bar clamps come in many different lengths, such as 4, 6, 7.5, 12, 24, 36, 40, and 48 inches.
Features of Bar Clamps
A bar clamp is a long piece of metal that is made to hold together big and heavy things.
The fixed jaw is put against one side piece to be held in place, and the bottom of the clamp, which is flexible, is tightened to the other side piece.
The moving jaw slides along the bar and is locked in place by an adjustable screw when it is in the right place.
Other Types of Clamps
C-clamps, bench clamps, and hand screw clamps are some of the other types of clamps you can buy in addition to bar clamps.
All of these clamps do the same thing, which is to hold things securely, but they look and work differently depending on what you need them for.
For example, sheet metal clamps are like locking clamps, but the clamp jaws are big, which makes them perfect for holding sheet metal and other similar materials.
Ratcheting band clamps are best for wrapping around an assembly, like a box with mitered corners or a cylinder with segments or slats.
Materials Used in Bar Clamps
Bar clamps are an important part of woodworking and metalworking projects that use more than one type of material.
Bar clamps usually have steel bars that go across and up and down.
Steel is a strong, long-lasting material that can handle heavy-duty clamping.
Steel is also hard to bend or break, which makes it perfect for clamping large, heavy pieces of work.
Steel is also used to make the large screw that is used to tighten and loosen the clamp.
The part of the clamp that touches the workpiece directly, called the clamp pad, is usually made of wood.
Wood is flexible and easy to work with, which makes it a good choice for clamping small or oddly shaped pieces of work.
The clamp pad can be made of plywood or solid hardwood with a thickness of 5/8".
You can also make wooden bar clamps without using any hardware.
All the parts can be made of wood.
Bar clamps can be made of steel, wood, aluminum, or even plastic, in addition to those two materials.
Aluminum is a strong, lightweight material that is often used to make bar clamps with quick-release mechanisms.
Plastic may be used for making the handles of bar clamps, as it is lightweight and comfortable to grip.
Choosing the Right Bar Clamp for Your Project
To make sure your project turns out well, you must choose the right bar clamp.
Consider the Task
How big and what kind of bar clamp you need for a project depends on what needs to be done.
Here are some examples:
- Bar or pipe clamps are the best option for edge gluing panels, as they provide enough length to span the width of the glue-up and also provide support for the panels.
- Light-duty bar clamps are perfect when you need a long reach and moderate pressure.
- Spring clamps are small and easy to store and can be used for holding work in place or doing light-pressure clamping.
- Strap clamps are useful for gluing up boxes with mitered corners or segmented or curved parts.
Types of Bar Clamps
There are many different kinds of bar clamps, such as:
- Sash clamp.
- Quick-release bar clamp.
- Pipe clamp.
- T-bar clamp.
Choosing the Right Number of Clamps
Most woodworking jobs should be able to be done with four bar clamps, four pipe clamps, and one strap clamp.
But the size and complexity of the project will determine how many clamps are needed.
Features to Consider
When picking a bar clamp, there are a few things to think about:
- Material: Bar clamps can be made of steel, aluminum, or plastic.
- Size: Bar clamps come in different lengths, typically ranging from 4 to 48 inches.
- Strength: The strength of the clamp is important to consider, especially for heavy-duty clamping.
- Stability: The stability of the clamp is important for ensuring even pressure across the workpiece.
Understanding the Strength of Bar Clamps
When choosing a clamp for your project, you should think about how well it holds things together.
In this article, we will talk about how strong different bar clamps are and how much pressure is best for different types of wood.
The strength of a bar clamp depends on what kind of clamp it is and what brand it is.
Here are some examples:
The DeWalt 6" Heavy Duty Bar Clamp can hold up to 1000 lbs.
- Yost Vises' bar clamps are designed to clamp with 120 lbs of force, while their 13000 Bar Clamps can produce precise clamping pressure ranging from 175-250 psi for hardwoods.
- Jorgensen steel bar clamps are medium-duty and can hold up to 600 lbs.
Recommended Clamping Pressure
For most joints, the maximum recommended clamping pressure is 250 psi.
It is important not to go over this amount.
When you tighten a clamp too much, most of the glue can be forced out.
This makes the bond weak.
Dale Zimmerman of Franklin International suggests the following clamping pressures for different types of wood:
- 100-150 psi for clamping softwoods.
- 175-250 psi for clamping hardwoods.

|Bar clamps are used in carpentry and woodworking to hold boards and planks together while the glue dries or when making big panels or frames. They are perfect for holding long pieces of wood together because they apply pressure evenly along the length of the workpiece. Bar clamps can also be used to put together furniture, cabinets, and other projects made of wood.
|In metalworking projects, bar clamps are also useful. They can be used to hold pieces of metal together so they can be welded or soldered, or to keep metal parts in place while they are drilled, milled, or ground. When working with metal, you need a clamp that can handle the high temperatures that are created during the fabrication process. Some bar clamps are made for metalworking and have pads that do not melt when they get hot to protect the workpiece.
|During auto repair, bar clamps can be used to hold parts in place. They can hold exhaust pipes, shock absorbers, and other parts in place so that repairs can be made. They can also be used to hold body panels of damaged cars together while they are being fixed.
|Bar clamps are useful in construction projects as well. They can be used to keep framing members in place while walls, roofs, and other structural parts are being built. They can also be used to hold drywall in place while it's being installed.
|Bar clamps can also help with plumbing jobs. They can hold pipes together while you solder or weld. They can also be used to hold pipes in place while making repairs or installing new plumbing components.
|Art and sculpture:
|Art and sculpture projects also use bar clamps. They can be used to hold pieces of metal or wood together while sculpting or assembling a work of art.
