How to choose the best joinery clamps?

A clamp is a tool whose purpose is to fix elements or materials during work. For example, this tool is used for gluing, joining, drilling, welding, sawing. There are several types of such a device, but the most popular are carpentry, locksmith, and welding devices. According to experienced furniture makers and carpenters, it is difficult to replace a carpentry clamp with another tool during work.

Carpentry clamps are used to grip and fix various parts. Usually similar tools made of wood or metal. After installing the clamp on the surface, the master will be able to use both hands for further work.

At the heart of a simple manual device is the main frame, as well as movable elements of a screw-like or lever type. The latter are engaged in fixing the movable part of the surface, as well as regulating the compression force. Some linkages are based on an axle and a lever.... Such tools are essential for fast fixing work on workpieces. In this case, the master makes a minimum of effort to ensure that the handle moves, and a large clamping force is created in a split second.

Among all the variety of clamps, clamps are very popular with craftsmen, since they are easy to make yourself. In addition, woodworkers use the following types of this tool.

Such devices are represented by devices in the shape of the letter F. This type of tool has a jaw of considerable depth, which fixes parts at a greater distance from the edge. The sliding-type head jaw may have an adjustment screw or a lever. At the same time, the clamps can be thin and narrow, as well as more massive, used for heavy work.

Such a device is inexpensive. The inconvenience of using such a tool is expressed in the fact that it needs to be held with both hands, while twisting.

Clamps of this type are based on a nylon or belt belt. With the help of the latter, the clamping force is transmitted to the mating elements. Thanks to the strap clamps, the uniformity of the clamping and the strength of the fixation of the workpieces are ensured. Band tools are used to produce frames, chairs, countertops and more... With this universal clamp, you can connect parts, drill parts of the surface at the desired angle.

In the strap clamp, the strap is long enough to wrap around a small case. Tape without corners can damage the edges of the workpiece. In this case craftsmen are advised to buy special corners that expand the functionality of the clamp.

These tools are used in many carpentry processes, so almost every craftsman has them. The device may be of different sizes, but the most demanded devices are 10 and 15 centimeters... It is worth purchasing only high-quality G-shaped clamps, otherwise the product may sag and create difficulties during operation.

In terms of the constituent material, this device can be forged steel or less durable, made of cast iron.

There are a few more less popular, but still well-known types of clamps.

The advantage of this model of the clamp is considered not only a spectacular appearance, but also strength, the presence of a comfortable T-shaped handle. Of the minuses, users allocate a lot of weight and the inability to adjust the size of the throat.

These clamps are perfect for clamping large workpieces. They are distinguished by a long rail and a movable part.

• The popular model of F-shaped clamps is recognized Bessey GH40, which is characterized by powerful clamping force, high clamping speed, high-quality workmanship, and also does not slip during operation.
• Gross 20717 Is a tool that has a strong steel structure and a reliable locking mechanism, however, when working with the jaws, rubber linings can slip.

Clamps are classified as large-sized structures that fix surfaces by screwing on a moving element.

The choice of a clamp is a responsible matter, since the quality of the work performed depends on the characteristics of the tool.

When buying an instrument, there are a few things to pay attention to.

• Clamp option... The classic models most often have screw mechanisms that can redirect the moving element of the device. Quick-clamping devices are characterized by great convenience, with the help of which you can open and fix the part using only one hand.
• Clamping force... The fastening mechanism of the parts is influenced by the clamping mechanism. Depending on the model, this indicator can range from 20 to 1000 kilograms. In this case, the choice of the clamp will be influenced by the nature of the operations and the materials of the workpieces.
• Functionality... Currently, the consumer can buy a model of the clamp, which, in addition to compressing the part, will be able to act as a spacer.
• Weight and materials of manufacture... Cast iron and steel models will prove to be the most durable. However, such devices are heavy. Some clamps are made of aluminum or synthetic material. Therefore, they are not only durable but also lightweight.
• Anti-corrosion performance... The clamp can be used for several decades if it has reliable corrosion protection. For this purpose, many manufacturers cover their products with galvanic or varnish-and-paint substances.
• Optional accessories... For comfortable work, the clamp is often equipped with additional devices. For example, a T-handle, which is responsible for adjusting the clamping force. To prevent damage to the part, the manufacturer has provided rubber pads for the sponges.

The vice is considered an indispensable carpentry tool. Since buying a new clamp is expensive, you can try to make the device yourself. Homemade pipe or metal tools should be made using drawings.

To make a clamp at home, you will need to prepare a grinder, welding and a drill. In addition, the master will need the following materials:

• profile tube with dimensions 50x25;
• corner 30x30;
• bolts m16 and m8;
• extended nut m16;
• bearing 202;
• iron strip 10 millimeters thick;
• timber made of wood with dimensions 40x40.

First, you need to cut off a meter of pipe and weld an M16 nut to its end. In this case, the master should place a 10 mm strip under the tube. After that, you need to tighten the bolt and fill the bearing. A corner is welded to the bottom of the product.

The next step is to make a thrust area that should move freely through the tube. In the latter, it is worth drilling a hole for mounting the m8 bolt. An adjustment hole is drilled after 5 centimeters. In the bar, you need to make a hole for the bearing.
