A do-it-yourself clamp facilitates the work of the master and saves him money. Do-it-yourself quick clamp How to make clamps

Clamp is an important tool for any craftsman. At the same time, the specifics of his work does not play a special role: a carpenter, a locksmith. This device is indispensable, therefore it is often used. For example, when gluing wood blanks to secure a sheet, slab, board, etc.

On the market you can find big choice clamps. They differ in the material from which they are made, sizes and other characteristics. Despite this, as practice shows, to pick up best option hard to work. Most tools have their drawbacks, which provoke difficulties during use. One of the most important is associated with a low strength indicator. This is explained by the fact that the manufacturer wants to save costs on the manufacture of products, therefore, uses low-quality materials.

If you want a durable and reliable device, then the most the best option is to do it by hand. Such a tool will be an excellent assistant when working with wood and will last for many years. At the same time, it will save money on purchasing a new one, which is expensive. The design invented by you will help to solve individual tasks quickly and easily.

A clamp is a device that is simple in design, but very important when processing wood. It is used to fix in one position a board, a plate and other things that need to be cut. It is very important that it be comfortable for its owner. This will allow you to complete the work quickly and efficiently.

You can get a tool that will meet your requirements only by making it yourself. To do this, the first thing you need to start with is to decide on the type of structure. The tool can be made of both metal and wood. Their scope is extensive. It can be both universal and specialized device.

If we talk about varieties, then we can distinguish tape, pipe, edge and others. As for the clamps, the mechanism is represented by the type of angular, screw, mounting, manual, quick-clamping. The last option is relatively new. It appeared quite recently, but is already actively used by masters, as it is convenient and practical.

Preparation of drawings

Making clamps is a simple process. Despite this, it requires attention and responsibility. In order for the resulting product to be of high quality and reliable, it is necessary to think through everything to the smallest detail.

First of all, you need a drawing. On a piece of paper, you can reproduce the device as it will be in the future. You can prepare it yourself. But here it is necessary to have certain skills in solving such problems.

And, of course, the best option is the help of a professional. He will take into account your wishes, prepare an individual drawing. But for his work you will need to pay a certain amount.

What is necessary?

Depending on the purpose for which the tool will be used, the material from which it can be made is selected. The highest quality and most reliable products can be obtained from wood, metal, corners, pipes and other things. These materials are great for making a clamp. It is also worth considering their high rate of strength and durability.

In addition, you will need studs, nuts, plywood boards, slats. Their size is determined based on what the device will be. They are indicated on the drawings.

Manufacturing process: instruction

The process of manufacturing a clamp consists of several stages. It can be started after the drawings are prepared and necessary materials. At the same time, it is necessary to work carefully and accurately.

The first step is to fix the bars on the surface of the table. These will be used to secure the clamp to the workbench. To do this, you need to make holes on them by drilling. Then, using nuts with studs, press them tightly.

The second stage involves work with the lower beam. It must be stable on the surface. To do this, it is placed horizontally. The next one is placed on top. It should be edge to the countertop.

After that, you need to install plywood boards. A bar is placed on them, and everything is attached to the table. In this case, the bottom edge of the plank should protrude slightly. It will be enough three centimeters relative to the bar. After the elements are correctly laid out, they must be drilled through and fixed with studs. In this case, each board performs its role. One is responsible for how fixed lower bar, the second one acts as a clamp.

At the same time, it is important to equip the structure with a plywood strip that moves. Studs for fastening are used different. They differ in length. So, long ones are responsible for the working stroke, short ones - for fixing the device to the table. As for nuts, their role is also great. They fix the part of the tool that moves and regulate the clamp itself, its strength. Thus, they act as leverage.

Do-it-yourself quick clamp

Do-it-yourself quick-clamp clamp is one of the most common types of construction. She happens different types: angular, lever, manual and other. Its main difference is that the device provides a quick clamping of the material to be processed.

It is not difficult to make such a clamp with your own hands. To do this, it is necessary to take into account some of the nuances of the case. The first is related to a good clamp. A lever is excellent as it, which helps in working with the tool. Such a device will be convenient and practical to use.

If the tool is used for welding, then it is necessary to choose corner model. She will allow necessary work perform quickly and simply, as it is a universal fixative.

Each carpenter uses clamps during work, securely fixing the workpieces with their help. You can make such a device yourself, and there are several options for execution.

Clamps are simple, universal and specialized. Appeared not too long ago the new kind products - quick-clamping. Such an element can compress up to 450 kg. It will be useful to study the instructions for creating do-it-yourself wood clamps.

corner option

Regardless of the type of clamp, it must firmly clamp the parts for their connection or processing. Corner joinery helps to fasten wood blanks at a certain angle (most often 90 °, but there are others). This is indispensable when assembling furniture and frames.

In order to make such a wooden clamp with your own hands, you will need the following materials:

• two wooden bars 25 mm thick hardwood;
• plywood 12 mm thick or more;
• self-tapping screws, studs;
• jigsaw or hacksaw;
• drill.

A square board with a side of 25 or 30 cm is cut out of plywood. Two bars are fixed on it at an angle of 90 °.

Important! The angle must be measured from high precision, since the correct fixation of parts depends on it.

First, the bars are glued, then they are countersinked, holes are drilled with a drill and self-tapping screws or other fasteners are screwed in. Perpendiculars are drawn from the center of the bars - screw studs will pass here.

At a distance of 20 mm from the corner bars, persistent bars are fixed, maintaining a gap between them. It should be slightly larger than the width of the parts to be clamped with a homemade clamp. It is better to screw in the studs immediately, before fixing the stops. You will also need to cut out the movable pads that will be connected to the pin (when it is unscrewed, the workpiece will be pressed against the corner bar).

As a screw, it is best to take studs with a rectangular or trapezoidal thread. The thread pitch is 2 turns per cm. It is very good if on the stud on one side there is a pillar of a slightly smaller diameter than the thread. It can be used to fit the handle. On the other hand, a slightly larger diameter rear sight is desirable to fit the bearing.

So, in the simplest clamp, one end will be fixed, and the other will advance through a worm gear.

To release the workpiece, you need to move the bracket to the required distance and turn the knob a few turns. Thus, the element is fixed. After that, you can release the mechanism and the workpiece will be released.

The simplest version of this model is equipped with a rail structure. The guides, which are arranged in parallel, have cut grooves at an equal distance. Fixed stops are fixed with metal rods. They can move exactly along the width of the blanks. At the end of the beams, fixed stops should be installed, which have a worm gear. In the usual way, clamping is done with a stud and a furniture nut.

Self-clamping option

For gluing parts, it is better to choose the simplest clamp model, which has an F-shape. The stores sell various models, which consist not only of wood, but also of metal. The cost of such tools is high. Therefore, many craftsmen prefer to make them with their own hands.

For small operations, a cam-type clamping clamp is perfect. For example, if you need to glue small parts or fix workpieces. Such a model works in the same way as the f-shaped element. The tool includes 2 jaws and guide rails. Sponges: mobile and motionless. For reliable clamping, it is necessary to fix the workpiece well and turn the cam 90 degrees.

You can make such a tool yourself with minimum set tools and materials. Before starting, you should draw a drawing of the product. You can use any material for manufacturing, as well as change the standard sizes as you wish.

The tire is made of wood or metal. Small bolts and rivets can be used instead of metal pins. It is recommended to make movable and fixed jaws at the same time, as they mirror each other. Their width and length can be changed to increase the grip of the product.

For gluing boards (shield)

Clamping clamps are needed to fix the plots, which, after the glue has dried, are used for furniture panels. Such products differ from simple ones in their length. In other words, they have a large jaw range. If you buy such material in a store, you will have to pay a decent amount. Therefore, craftsmen prefer to make clamping mechanisms on their own.

Materials and assembly steps

In order to make wood clips, you will need the following items:

• beech or birch bar;
• drill bit;
• pipe 2.5 cm;
• mortise nuts of suitable diameter;
• a nut that has a rounded knob (used for decoration);
• cutter with a diameter of 2.5 cm and a long hairpin.

The basis of the material is a pipe, from which a piece of the required length is cut. Depending on the size of the sponges, it is necessary to saw the bar. The pieces should be from 15 to 20 cm. For the free movement of the timber through the pipe, make a hole with a diameter of 2.5 cm at a distance of 2.5 cm from the edge. Parallel to the hole, cut from the same end. To fix the sponge on the pipe, connect the hole to the end.

For the drive nut, an additional hole must be drilled to the side of the cut. It is necessary to hammer a nut into it and tighten it from the back with a bolt. To fix the sponge, clamp the pipe in the hole. To move the pipe, unscrew the bolt, then move the element and repeat all the steps again.

There are 2 jaws in the lower clamping part, it is slightly larger than the upper one and has an additional nut. In terms of structure, both parts are the same. An additional driving nut is located at the opposite end of the pipe, into which a stud with a wing nut is inserted.

In the second collapsible movable part, there are no clamping parts such as cuts and nuts. The size of such an element is also rather big. In this part, it is necessary to make a recess for the stud device.

Operating principle

The principle of operation of the clamp is very simple. It is necessary to dilute the extremely sponges so that they are at a distance of 3 cm more from each other than the width of the shield to be installed. Next, you need to fix them on the pipe. To do this, clamp the nuts that are located along the edges. The blanks must be put on the tubes and sealed with glue. Then they need to be pulled together with the help of the “lamb” rotation.

With the ability to use a grinder and a welding machine, you can make the same clamp for gluing wood from metal.

To maintain the plane of the plot with tubes, it is recommended to arrange the clamps in checkerboard pattern. The main advantage of such a tool is the ease of manufacture and operation.

Special clamp designs

Having mastered the skills of making clamps of a simple form, you can improve them and make devices for connecting complex parts.

There are homemade clamps made from a wooden hanger, which is sawn into pieces. They combine wood and steel, make more comfortable handles that allow you to quickly tighten the screw. This is especially important if you need to frequently change position or use several clamps at the same time. In the case of complex blanks, you can first cut them out of paper, and then transfer them to plywood.

Although welded metal products are more reliable, wooden structures also used not only for carpentry, but also for turning, carpentry. You do not need to have special skills to create a clamp. You can make such a product from wood in unlimited quantities with your own hands. It will only take a certain amount of time for the manufacturing process.

Carrying out locksmith or carpentry work in places not equipped for this is inevitably associated with the problem of fixing workpieces. It is very difficult to prevent them from moving around the table or workbench during processing, unless they are equipped with special clamps, vices or other fixing devices. One of these devices, simple, affordable and versatile, are clamps. We will tell you what they are and how they are used, as well as give detailed instructions for making reliable clamps with your own hands.

What is the tool for, its device and types of tool

Clamp refers to additional carpentry and metalwork tools. The main purpose of the clamps is to fix the workpiece on the support surface or several workpieces for gluing them together, therefore, the design of the tool must include at least two elements: the support surface and a movable jaw equipped with a locking mechanism. The movement of the movable jaw is carried out, as a rule, with the help of a screw or a lever, which makes it possible to increase compression and prevent reverse movement during operation. Depending on specialization and design features distinguish the following types of clamps:

1. Screw G-shaped - the most common, they are distinguished by their simplicity of design and relatively low cost. Represented by a metal bracket, on one side of which there is a supporting surface, and on the other, a threaded eye with an adjusting screw screwed into it. The inner part of the screw is equipped with a working sponge, the outer part is equipped with a handle. The tool is effective when working with heavy, large workpieces of a simple shape.

   Clamps of this type are suitable for working with large workpieces.

2. F-shaped - more versatile, their supporting surface is fixedly fixed on a long rod, along which the working block with a sponge slides. Movement and fixation of the block is provided by an auxiliary screw or a step-by-step pressing mechanism.

   Objects are fixed due to the auxiliary screw and step mechanism

3. Pipe - allow you to fix large-sized workpieces by varying the length of the pipe. They consist of two separate elements - a base plate with a screw clamp and a sponge sliding along the pipe.

   Clamp suitable for working with overall workpieces

4. Corner - designed to simplify the joining of workpieces at a right angle, for which they have two supporting and working surfaces. They are divided into two subspecies. The first involves the presence of two clamping screws located perpendicular to each other; the second is equipped with one screw with a double-sided angle block at the end. Very rarely there are specialized clamps that allow you to place workpieces at an acute or obtuse angle.

   Clamps of this type simplify the docking of workpieces at right angles.

5. Tape - equipped with a flexible element and several sponges floating on it. By fixing the jaws in certain places of the tape and adjusting its tension, it is possible to process workpieces of complex shape.

   The tape clamp is equipped with a tape element that allows you to fix the workpiece around the perimeter

6. Pincer - consist of two hinged parts and a spacer spring. In practice, they are rarely used due to the relatively low reliability of the joint, however, they provide the maximum speed of installation and removal of the workpiece.

   Such a clamp is rarely used due to the low reliability of the joint.

At home, clamps of the first are most often made. three types, since they are not too demanding on materials and production technologies, and also allow you to solve most household tasks that require the use of an auxiliary tool.

You will find more information about the types of clamps in our next material:

How to make a carpentry clamp with your own hands: step by step instructions with drawings

To make clamps at home, it is enough to have basic plumbing and carpentry skills. Used as materials wooden beam, rolled metal, pipes and fasteners, in particular, bolts, studs, nuts, pins. For joining metal parts of clamps, it is desirable to have an electric welding machine. When performing any work, the main thing is to follow the instructions and observe safety precautions.

Making a screw type tool

This type of clamp will help to fix wood workpieces well.

A clamp made according to this technique is perfect for fixing small wooden blanks- plywood, fiberboard sheets, OSB and chipboard, as well as boards and thin timber. We suggest that you choose the scale yourself, but otherwise it is better not to deviate from the following sequence of actions:

1. Transfer the templates of all wooden parts to thick paper or cardboard in accordance with the selected scale.
2. Using the template, transfer the image to a suitable board width. Better not to use pine boards, but harder wood.
3. Using a jigsaw, cut out all the details. Correct the shape with a file, and sand the surface sandpaper.
4. In the "jaws" mark and drill holes for the axle bolt. Lengthen the hole of the upper “jaw” with a round file so that its length is 1.5–2.5 of the bolt diameter.
5. In the handle, drill a hole for the nut, with a diameter corresponding to the number of the wrench. With a needle file, give it a hexagonal shape. Install the nut inward with epoxy or cyanoacrylate.
6. Assemble the clamp - fix the axial bolt in the lower “jaw” with glue, install the rear loop on the screws, put on the upper jaw and, placing the washer, install the handle. Stick soft pads on work surfaces.

An even simpler option is to make screw clamp from a hacksaw.

A simple version of a hacksaw clamp

In this case, it is enough to weld a support platform at one end of its arc, and a nut at the other, into which the adjusting screw with a sponge and a handle will be installed.

Homemade quick clamp made of wood

Making such a clamp will take more time

The use of F-shaped clamps significantly speeds up the workflow. But the manufacture of the clamp itself is somewhat more complicated than the creation of its screw counterpart. You will need to do the following:

1. Transfer the images to the lumber as described above. Accurately observe the specified dimensions of the parts and the location of the pin holes.
2. Cut out the details with a jigsaw, use it to make a narrow slot in the movable sponge and deep slots for the axle plate. Using chisels, select the groove for the cam lever.
3. Drill holes for the pins. Treat all external and internal surfaces of the parts with a file, and then with sandpaper.
4. From metal strip cut the axle plate with a grinder, grind it. Drill holes for the pins.
5. Assemble the tool by placing the jaws on the plate using the pins. Insert the cam into the movable jaw. Stick on work pads.
6. Check the function of the quick release clamp. If necessary, change the shape of the working part of the cam lever.

Rough fixation of the lower jaw on the axle plate can be done by wedging its guide pins, inserting an additional pin, screw clamp, or in another way.

Metal pipe

For the manufacture of such a clamp, a metal pipe is required.

For such a tool, three metal rings are required, inner diameter which corresponds outside diameter the pipe you have, instead of which, by the way, you can use a metal rod. In the presence of a welding machine, the process of manufacturing a clamp is reduced to the following algorithm:

1. Weld support pads to two rings, which can be made from a steel corner; install a nut on the third ring, and weld the ring itself to the end of the pipe.
2. Weld an impromptu handle made of a metal rod to the head of a long bolt, screw the bolt into a ring with a nut.
3. From the free end of the pipe, put the ring of the upper movable sponge on it. In the ring of the lower jaw, make holes for the fixing pins.
4. Install the lower ring on the pipe.

The pipe clamp is optimally suited for holding furniture elements during its assembly, it will be convenient in construction and installation work and other similar operations.

corner

For the manufacture of this type of clamp, you can use wood, metal or duralumin. Between themselves, they differ not only in material, but also in clamping force and the size of the fixed workpiece. Our next article presents detailed instructions tool making:

Both at home and in professional activity associated with the processing of wood and metal, clamps will become indispensable assistant. By following the instructions and having a simple set of materials, you can make this tool with your own hands.

Hi all brains! In today's project we will make do it yourself wooden clamp.

All elements used are standard size and can be enlarged to make a clamp bigger size. So you get a set of several clamps!

You may not have any special equipment, like I do - this should not scare you! Almost any problem can be solved in one way or another, any craft can be improved. I made 3 prototypes before I got the perfect clamp for me. Don't be afraid to experiment and make mistakes!

Step 2: Materials Used

In this project, a set of four clamps is made, but the amount of materials is indicated for one clamp. Just multiply by the number of clamps you need and get the amount of materials you need.

- Hardwood 1.9 cm thick and at least 2.5 cm wide (I used pecan wood)
- 1/2 inch steel bar (12mm)
- 1/4 inch stud 20 threads per inch
- 1/2 inch nuts (12mm) x2 pcs.
- 3/32" spring pins (2.38mm) 3/4" long (19mm) x2 pcs.

You will also need a 1/4" 20 TPI tap for barrel nuts, and a 13/64" (5mm) tap drill.

Step 3: Splitting the Wood

The best way I have found to make something is to try to make all the required parts in one operation. Therefore, to begin with, cut the material needed for sponges and pens. The handles are made from a 3/4" x 3/4" (19x19mm) square blank and the jaws will be 1" x 3/4" (25x19mm).

Step 4: Cut out the handles

Set your machine to a 33 degree angle to cut the handle blank to the desired shape. You can use a 1/2" nut as a spacer to get the required thickness.

For this task, I used my band saw. Just go over one side, then flip from one side to the other and make a second cut. This will provide a hexagonal shape for the one side you are cutting. Then cut the second side in the same way.

When finished, turn your machine back 90 degrees and cut the handle stock 2 1/2 inches (64mm) long.

Step 5: Clamp Jaw Blanks

Now cut off a corner on the lips. Cut as you like. I cut my corner piece a bit long, and then used it to cut a 15 degree corner piece on one side for the other blanks.

For those of you who like to use a carpenter's corner for cutting, consider that the slope of the line (steepness) is 2 inches (50mm) by 2 3/4 inches (70mm). Angle is mounted 1/2" (12mm) apart or centered in a 1" (25.4mm) blank. I recommend cutting the corner first, then cutting the jaws to 4 inches (102mm). So less likely to make a mistake.

When finished, mark A and B on the jaw halves.

Step 6: Drilling Jaw A

Starting with sponge A. Drill two 1/2" (12mm) holes through one side and two 1/4" (6mm) holes through the top.

The first 1/2" (12mm) diameter hole is located 3/4" (19mm) from the back and is centered in the sponge blank. The second hole is located 1 3/4" (44mm) from the back of jaw A. Two 1/4" (6mm) diameter holes are located in the center of the top of the jaw 3/8" (9.5mm) from each side and intersect with 1/2 inch (12mm) hole centers.

Step 7: Sponge B

Sponge B is slightly different from sponge A. It does not have drilled holes 1/2" (12mm) diameter, and the 1/4" (6mm) hole in the back is only 1/2" (12mm) deep.

Place jaw B in the same way as previously placed jaw A, drill 1/4" (6mm) diameter holes 3/4" (19mm) and 1 3/4" (44mm) from the back. Be careful not to drill all the way through the back hole like I did. That's why I marked the sponges with the letters A and B.

Step 8: Threaded Studs

Take a good hacksaw sheet metal and cut the 1/4 inch (6mm) threaded stud to the desired length. You will need a 4 1/2" (114mm) blank and a 5" (127mm) blank for each clamp you make. Set them aside for now, we'll get back to them in the pen making step.

Step 9: Cylindrical Nuts

Cylindrical nuts are drilled steel round blanks with 90 degree threads inside them.

I made mine by cutting a 1/2" (12mm) piece of stock into 3/4" (19mm) pieces, then drilled holes and tapped with a 1/4" tap, 20 turns.

Step 10: Chamfering the Clamp Handles

All handles will be chamfered at one end. This makes them appearance more attractive, removes sharp edges, and makes them easier to hold in your hand.

If you have strong hands, then use a sharp cutter to create chamfers. Simply clamp the handles as shown in the photo and cut off the edges by 1/8 inch (3mm).

Step 11: Continue Finishing the Handles

In order for the knobs to fit a 1/2" nut, they must be cut to a diameter slightly larger than the hole in the nut so that the threads of the nut will securely engage the wood surface and create a secure connection. This is where it would come in handy lathe on wood, but in the absence of such, it will have to be done manually.

Press the stop block against the saw guard and use the 1/2" nut to set the depth of the cut and ensure desired distance from the fence. Next, take a wooden blank and make the necessary cuts.

You should end up with a drawing that looks a little like the Jewish Star of David. After that, cut off the excess protrusions.

Step 12: Handles and Removing Corners

The 1/2 inch nuts won't fit on the handles until you have the corners turned on them. At this stage, practice on some unnecessary workpiece, and only after that use a real pen.

Clamp the handles and grind until you get the perfect round shape.
Next, screw the nut onto the tip of the handle. Do it carefully.

Step 13: Finishing the Handles

Screw on two 1/4 inch nuts (6mm) and tighten them on the threaded stud so that it is securely fixed in the jig. Next, round off the ends with a metal file so that the handle moves smoothly. Make sure there is at least one inch of material protruding from the jig, then screw in wooden handle as far as possible. Use wrench for tightening to the base and aligning with the handle. Do not overtighten, lower the nut down until it is all the way down and then align with the handle.

Finally, you need to insert the pin into the handle. Drill a 3/32" (2.38mm) diameter hole in the center of the nut, threaded studs and hammer in the pin.

Step 14: Finishing the Job

Well, that's almost all. You have made all the necessary preparations. Now they need to be connected all together to get the finished product. We only need to sand the surfaces to remove sharp edges, edges and apply a finish coat. This is the nicest easy step to follow.

put on rubber gloves and rub a little drying oil into the surface, then complete this process by rubbing wooden surface wax, and enjoy the result!

I hope you enjoyed this project. You can also upgrade the manufactured clamp for clamping objects different size.

Clamp is an auxiliary tool , which is used to fix the boards when they are connected in a given position. Also, the clamp is suitable for holding boards during their sawing, for wiring a hacksaw blade, connecting various elements. Parts that require machining can be nested in the tool. Then, using a movable element, they are clamped with sponges and get to work. To securely hold parts in position, it is recommended to use two or more clamps.

Home-made staples are often made of metals or wood, and in terms of their characteristics they are not much inferior to purchased, factory-assembled ones. Since the design of the clamping device is simple, it will not be difficult to understand the principle of its operation in order to make it yourself.

Making a screw metal clamp

Before starting work, you will need to prepare the necessary materials. For the basis of the structure, a steel sheet one centimeter thick is suitable, any even trimming of the same thickness. The length of the workpiece is arbitrary, but they try to choose it taking into account the working distance of the clamp.

Main manufacturing materials:

• steel sheet;
• long bolts;
• nuts.

A drawing is being made. On the material of the workpiece, the future body of the tool is marked, which in appearance resembles the letter "C". Instead of steel sheet you can use a piece of profiled pipe, bent in the form of the letter "C". There are no special requirements for the thickness of the workpiece, but the design must be reliable. The choice of length is made taking into account the dimensions working area, workpieces.

After marking, the part is cut out of metal. At home, small blanks can be cut with a grinder. But when making clamps of large dimensions, it is recommended to use cutting torch, acetylene torch. The next stage is processing, grinding the workpiece. All sharp edges, sagging, formed when working with gas welding equipment, are knocked off with a file, and the surface is polished with sandpaper. This must be done so that when clamping the workpiece, you do not cut yourself on sharp edges.

Having prepared long bolts M 8, M 10, proceed to fasten the moving element. Why, on one side of the workpiece, nuts are welded under the selected bolts. In the absence of bolts, you can pick up hexagons, steel rods of the desired length with pre-cut threads.

At the inner working end of the screw, a flat, even part is welded, on which the function of the sponges is assigned. On the reverse side of the screw, a lever made of stud scraps is attached by welding. Its presence will speed up the process of clamping workpieces , further reducing the amount of effort applied. This completes the assembly of the clamp with your own hands.

Angle clamp device

When making a corner tool for furniture assembly, it is important to accurately maintain a right angle of 90 °. Main available materials are corners with steel strips. For work you will need:

• 40 mm steel corner 3-4 mm thick;
• steel plates 40-50 mm;
• threaded studs;
• bars for collars;
• nuts;
• welding machine;
• electric drill, taps.

Angle clamp is the most difficult to manufacture, but when carrying out certain types of work, you cannot do without it. On the initial stage corners are welded to the steel plates at a right angle, and nuts are welded to each of the corners, which will serve to create a worm structure. Another option is to drill a hole in the corner and cut into it with a tap internal thread. The width of the working gap is selected taking into account the size of potential workpieces, but too much stroke of the clamping knob reduces the strength of their fixation.

For processing workpieces of different sizes, it is recommended to prepare several clamps!

The stud is screwed into the welded nut. At its end, an emphasis is assembled from metal washers of various diameters, which should scroll freely when the pin is rotated. On the reverse side of the collar, a hole is drilled for a metal rod. Used as a lever, it will transmit more force, so it will be more reliable to hold workpieces.

Wooden clamp - we will make from the remnants of the boards

The most popular is a wooden quick-clamp clamp, but a tool of a similar design can also be made of metal. Despite the simplicity of the design, it is very convenient when performing various tasks.

The presence of two identical clamps expands the scope of their application!

For assembly, you will need to prepare the following materials:

• pieces of boards;
• studs with pre-cut threads;
• nuts and lambs corresponding to the thread of the studs;
• slats.

First, two threaded studs of the same diameter are prepared. They must be 200 mm long. The nuts are matched to the stud threads. Two slats are prepared, preferably from hardwood. The best choice there will be oak, beech, birch, ash. Reiki are adjusted to the same size. To do this, the excess length is sawn off, and the cut is subjected to grinding. After that, two holes are drilled in each of the rails with a small tolerance. Moreover, the location of the holes on each of the blanks should ideally match, and their diameter should correspond to the diameter of the studs.

Strips of plywood can be glued onto the surface of the rails. They are customized according to the size of wooden blanks, holes are drilled. The studs are inserted into the holes obtained and securely fixed with nuts on one of the rails on both sides. Washers are placed under the nuts to prevent material from being squeezed. This bar will always be fixed, but the other will be able to move freely along the guides in the form of studs.
