Mini hacksaw for metal with their own hands

Mechanical saw on metal with their own hands: photo and description

To make a more powerful machine for cutting metal parts, you need to use a separate motor. In addition to this you need to prepare drawings of the device in the assembly, tools for making homemade cutting equipment, consumables. These include:

  • Metal profiles, angles, plates to make a frame with a working table.
  • Bearings, shaft, two pulleys.
  • Electric drill, angle grinder, welding machine.

In addition, you will need fasteners, tooling on the power tool.

To assemble a quality machine with their own hands will be possible only after studying each of the key elements separately.

Engine

The power of the electric motor depends on how hard the metal will be processed, how often the homemade machine will be used. Optimal power range is 1.5 to 3 kW. The number of revolutions should be no less than 2500 per minute. Do not forget about the required amperage. For a home workshop, the best connection would be a general network of 220 volts. It is desirable to choose a motor with the ability to change the number of revolutions.

Separately we must talk about the diameter of cutting discs. The optimal dimensions are between 300 and 400 mm. The larger the disk in size, the more revolutions it requires for quality processing. However, any consumable indicates the maximum number of revolutions per minute that are allowed during cutting. Most often the maximum is at 4400 rpm.

Drive

To make the drive, you need to use belt drive. To make it, you need to find two pulleys that are equal in diameter. One pulley to fix on the shaft from the electric motor. The second is installed on the drive shaft of the abrasive disc. Further the shaft is fastened on two bearings. A motor is to be installed on the back side of the ready made pendulum. Four bolts are used for this. The fasteners should be placed in the slots, which will allow the motor to be displaced by 5 centimeters. This will make it possible to choose the optimal belt tension. With a sliding motor on a homemade machine it is easier to change consumables, belts.

Console pendulum

Arm is a key part of the equipment, the assembly of which determines the accuracy of cuts. For the base of the pendulum we need two bushes, which need to be made from a metal square with dimensions 4×4 cm. Their height must not exceed 10 cm. It is necessary to make holes in the stands, which are necessary for fixing the shaft sleeve. Then a rocker arm is welded to it. A surface is installed to secure the electric motor. The lever for lowering the disk to the workpiece is calculated according to the person’s desire.

Work table

  • Make a cut, through which the blade will pass while cutting metal workpieces.
  • Size depends on the stroke of the pendulum, the diameter of the tool.
  • You can also build a broaching mechanism.
  • Set the side clamping, so you can clamp the workpieces during cutting.

Optimal thickness of sheet metal under the work table is about 4 mm.

How to make a pendulum metal saw with your own hands?

[The metal pendulum saw] is an essential tool for machining this material. Because metal is so strong, not every saw can handle it.

The pendulum saw is popular because it does its job effectively, and it doesn’t matter if you bought it in a store, or if it’s homemade. If the price of a suitable saw does not suit you, it is possible to make the tool yourself.

To assemble the saw with their own hands is not difficult: in the article you will learn about its main functions and how to make it.

Tooth varieties

Most common in hand saws are these tooth shapes:

  • dagger tooth. Used in classic wide and narrow hacksaws as well as in beam saws. Tooth is in the shape of an isosceles triangle, so such hacksaws can work in both directions. Tooth spacing is most often 1/3 of the blade thickness per side. Teeth are equally spaced apart from each other. This type of set is designed for cross-cutting sawing, as it is aimed at tearing the wood fibers. A longitudinal cut is almost impossible because the tooth does not break, but splits the fibers, and thus gets stuck between them
  • chisel tooth. Shaped as an asymmetrical right triangle. Pole saws and prize saws most often have such teeth. Saws with these teeth work in one direction only. The tip of the tooth is sharpened across the blade, so it works like a chisel. It is used exclusively for cross cutting, because it clings to fibers during longitudinal sawing
  • slanting multi-purpose tooth. Something in between the two types described above. Shape. asymmetrical triangle, tilted in sawing direction, but with smaller sawing angle. Front edge is sharpened at 60° to the blade. Such sharpening makes it possible to use the saw both for longitudinal and cross cutting. Cogging saws are equipped with these teeth

What are handheld metal saws for?

Metal handheld hacksaws are designed for cutting metal materials. This is not the only purpose of the tool, as it has proven good for materials such as plastic, chipboard, styrofoam, polystyrene foam, plexiglass, ceramics, laminate.

Considered saw for sawing metal. it is a very necessary tool in the household, because in the absence of an angle grinder, it can always help in the situation. to saw off the cap of an oxidized bolt or re-saw a steel wire. The big disadvantage of such a tool is a large expenditure of physical strength and time. The presence of fine teeth is reflected in the time it takes to achieve the result. To get the result from the master requires not only the application of titanic force, but also patience. The result of prolonged and persistent work with the tool is the most accurate result, which sometimes exceeds the cut with an angle grinder.

It is important to pay attention to! the hand-held metal saw trimmer blade is as thin as possible, due to the fine teeth in the design of the blades.

Sharpening two-handed saws yourself, or how to simply restore an old long hacksaw

If you have an old two-handed hacksaw Druzhba-2 in your garage, then before using it, it is recommended to restore its integrity. Before using the tool, you should pay attention to the following points:

  • Handles. made of wood handles may have dried out during a long period of non-use, so it is not excluded that they can freely fall out of the holes. You can restore the serviceability of the handles by dipping them in water for a few hours, so that they swell. You can also grind new handles on the tool, which does not require much time and effort
  • Presence of corrosion on the blade. signs of rust should be eliminated, and then treat the device with machine oil
  • Tooth sharpening. after a long time of keeping the tool in the garage, there is a high probability that the hacksaw needs to be sharpened

While restoring handles and removing corrosion are no problem, sharpening the teeth is just the opposite. A large saw requires a lot of time and effort to restore the integrity of the links. There is, however, an advantage in this case, because it is much more convenient to sharpen larger teeth. Although different from an ordinary hand hacksaw, the principle of restoring the sharpness of the teeth is similar. The step-by-step description on sharpening the teeth on a two-handed saw has the following format:

  • First of all, the tool has to be clamped. In the jaws of even the largest vise it will not be possible to do this, so we use two boards of appropriate length. Arrange the boards parallel to the blade, leaving only the teeth in view. If you don’t have a vice, you can use a clamp
  • You must start with the setting of the teeth. All teeth should be set to the same height. The presence of protruding links can be determined by eye, and to level them with the rest, you should work with a flat file
  • In the next step, you must line up the teeth at the same angle of deflection from the plane of the blade. To perform the setting you need a special tool. It is also recommended to make a template (model) in advance to check the adequacy of the separation of the links (or buy it). It’s necessary to set the teeth 0,5 mm from the plane of the blade or 1 mm from each other. Set-up procedure is performed one after the other. Not many craftsmen know how to adjust the teeth very often. According to the rules, it is necessary to do the resharpening no more than once every 5-6 sharpening of the teeth

Finally the tool blade should be treated with machine oil and used for sawing thick logs, trees and even lumber. During work, it is recommended to observe safety precautions in order to avoid injury.

While restoring handles and removing corrosion is not a problem, sharpening teeth is just the opposite. A large saw requires a lot of time and effort to restore the integrity of the links. But it has the advantage that a larger saw blade can be sharpened more easily. Although the tool is different from an ordinary hand hacksaw, the principle of restoring the sharpness of the teeth is similar. The step-by-step description on sharpening the teeth on a two-handed saw has the following format:

  • First, the tool needs to be fixed. It will not be possible to do it in the jaws of even the biggest vice, so we use two boards of appropriate length. Arrange the boards parallel to the blade, leaving only the teeth in view. If you don’t have a vise, you can use a clamp

Beforehand it is also recommended to make a template (model) to check the adequacy of the separation of the links (or buy it). Set teeth 0.5mm from the blade plane or 1mm apart. Set in sharpening turns. Not many craftsmen know how often to perform the setting of the teeth. You should not sharpen more than 1 setting per 5 to 6 sharpenings

Finally, it remains to treat the tool blade with machine oil, and resort to the use for sawing thick logs, trees and even lumber. It is essential to observe safety precautions when carrying out this work so as not to injure yourself.

How to make a home-made nozzle for the drill

Clamp a metal bar in a vise. Using a file at an angle of 20 degrees, saw symmetrical grooves with parallel faces.

The bearing is placed on the shaft and turned as far as it will go into the slots.

After this work it is necessary to make bushes to fix the bearing. To do this, the aluminum tube is cut in half at an angle equal to the angle of the bearing in relation to the axis. Then you need to drill holes in the bushes on a boring machine and cut the thread for the set screws DIN 913, 3.5 mm.

Shaft sleeves are put on the shaft and secured with screws.

Two washers are placed on each side of the shaft to reduce the wear on the bushings.

In order for the nozzle on the drill with their own hands to turn out strong and lightweight, the details of the construction fixture are made of aluminum, which is easy to handle. According to the dimensions given in the table, the parts must be made. At the same time the holes of both platforms, struts and guides should coincide. A through thread is cut into the legs to hold the entire structure.

Attention! Only two bolts are bolted, to the side of the shaft. The two opposite ones are installed at the end, together with the stop.

Two crosspieces are put under the holes in the uprights to act as guides for the rod.

For the manufacture of the rod, you must choose steel material, because the saw will be attached to it, and it bears the load. Two cylindrical head screws are screwed into the drilled holes in the rod.

The spacing between the two should be such that the bearing will rotate easily without play. Bolts to the rod should preferably be fixed with welded points, so that they do not unscrew.

Important! For free movement, the stem must be at 0.1 mm thinner than the guides. A plate that is pressed tightly against the rails with screws can jam the rod and prevent it from moving freely.

The second platform is screwed on from the opposite side.

The accessory on the electric screwdriver with your hands is almost ready. It remains to attach the saw holder and the stop.

The saw holder is a relatively small and complex part of the drill head. It consists of 4 parts. The upper and lower covers are attached to the side faces, between which the rod is inserted on one side and the saw blade on the other. The rod is fastened with a bolt. The blade. with two screws from the top, and additionally clamped on the side with a bolt that must pass through the hole in the shank of the saw, to secure it. This method of mounting prevents the saw from slipping under load.

Parts of the support are cut out on the milling machine. At home it is not difficult to saw them out with a file, clamping them in a vice.

Advice! Before drilling the holes, the parts of the holder must be glued together. This ensures the exact alignment of the holes when reassembling.

The Materials table shows the blank dimensions for a 12 wide metal blade.5 mm, and 1.25 mm thick. Double-sided blades are wider. For this reason it is advisable to have holders for different cutting tools.

The picture shows a schematic view of the holder.

The holder is put on the rod and tightened with the bolt. The deeper and tighter the holder sits on the rod, the more reliable the device works.

A blade is inserted between the jaws of the holder and fastened with 3 screws.

At the end of the process, the stop, made from an angle with a slot for the blade, is attached and clamped with screws. The drill bit with its own hands is ready.

How to make a saw?

If you need a saw, but the price declared by the seller is “biting”, it is high time to think about making a tool by your own hands.

For a saw designed to work on metal, you will need a more powerful electric motor, such as in Makita models, which will also be useful if you are going to saw thick trees.

If a more powerful tool is needed, it is better to make a pendulum frame. Pendulum variations are not only more powerful, but also very effective.

For the frame of the machine to be stable, steel rather than wooden corners should be used for its construction.

The frame is the base on which all the cutting and rotating mechanisms are mounted, so make sure that it is strong.

Before starting to assemble the saw with your own hands, look at the diagrams with its device: you can be guided, for example, by the machine firm Makita, t.к. It is a high-quality and functional device for metalworking.

Every home-built cut-off saw must be mounted on some kind of stable surface, usually a table.

You need to make sure it’s properly clamped, ie: “The frame is the base on which you can attach the saw.к., If it will wobble, it can not only ruin your workpiece, but also be dangerous for the craftsman.

The table for the tool must be special, and it is also better to make it with your own hands. For the bed you can use an old table from the kitchen, or metal or wooden trestle.

If you have chosen to use trestles, they must be connected using a board with a cross section of 50 mm. On top of the resulting base and you need to install the table top.

The table top can be made of metal plates with a width of 4 mm. To work you need two of them. Or you can use thick planks, which should be connected with a lintel of plywood.

When joining the materials, do not forget to leave a gap of at least 10 mm between them.

The most important thing is to keep the edges of the plate parallel to each other, otherwise the miter saw will not work properly.

When securing the tool to the tabletop, the saw should be in the center of the gap, and the plates should be positioned on its two sides. You need to make holes in the table, in which the saw will be fixed.

After installing it, you need to fix the motor so that the end saw can work. If you have made a small saw, the easiest thing to do is to attach it to the motor axle.

IMPORTANT NOTE: Choosing the right consumables for plasma cutting

However, for cutting thick metal the tool is not suitable, so if you understand that the low power in your work will not be enough, then immediately make a more powerful tool.

You can use a spindle from a bicycle as the transmission mechanism for a homemade saw. This includes the bearings and the shaft, which you will also need in your work.

mini, hacksaw, metal, their, hands

You can cut the spindle from the bike with a hacksaw. You need to install a sprocket on the bicycle shaft. The best part for this is the part belonging to the D6 or D8 motor.

In order for it to fit tightly on the shaft, you need to make a bushing for the transition.

The circular saw must be attached to the spindle, but before you do this, you need to determine the diameter of the device.

The diameter of the bushing should also match the diameter of the other parts, so that they all fit together tightly.

The spindle housing should also be fitted with a plate that is at least 5 mm thick. The sprocket is attached to the shaft, which has a homemade saw.

The sprocket should in its size of 2.5 times the spindle.

The chain is the last thing you put on the body after all the other parts have been set up and secured.

The price of parts, which the cut-off saw requires, will be much lower than the price of a ready-made saw, for example, by Makita.

  • table;
  • several plates;
  • A few bars and jumper bars;
  • an old spindle from a bicycle;
  • a bushing for the transition;
  • sprocket;
  • chain;
  • shaft.

Some of these tools you probably already have in your garage, others you can get very cheaply.

If you are not confident in your abilities, it is better to buy a ready-made tool.

The more so that the price of some Makita models is quite acceptable, and at the same time they have a wide range of functionality.

Before you buy a metal-cutting saw, study the offerings on the market and read up on different tool models.

It is better to choose an already proven machine, for example, a saw Makita, which has long proved itself on the market. Price of both circular and pendulum saws is affordable for a person with average income.

Selection Criteria

It is easy to get confused by the huge range of hacksaws. But the best models always stand out:

  • The universal length of the blade for working with different workpieces is 30 cm;
  • Ergonomic handle, which is rubberized, has grooves and sits easily in the hand (this can be felt on first contact);
  • Optimal weight. not too much, not too little (and the front part of the design should be lighter than the back, so that when the tool moves forward on the blade there is no additional load, which contributes to the breakage of the tape);
  • A unique blade, which has two different cutting lines on both sides (usually such bands are sold separately);
  • Manufactured by. Popular brands are Kraftool, Armero, BlackDecker, Vira, Stanley, Irwin.

The last point is very important because today the market is full of fakes that suffer premature wear and tear. they bend, crack, rust. So do not count on price leniency in the pursuit of reliability.

The open and working parts of branded metal hacksaws are always covered with a paper label, which serves as a kind of seal that guarantees high quality.

Also, the “cover” definitely protects the canvas and is removed in anticipation of work.

Choice of tool or what to look for

To choose the best handheld metal hacksaw, pay attention to the following parameters:

  • Length of tools and blades. Blades have different lengths, but if you choose a device, you should take the one that is convenient to work with. If the tool is selected for a specific purpose, then remember that the length of the hacksaw should be twice as long as the part you are sawing
  • Handle. To choose the best instrument, you need to take several models and hold them in your hand. The difference can be felt immediately, as some handles are uncomfortable. The tool with hollow handles is better not to take, because they are not reliable. The handle should be comfortable, and should lie well in your hand
  • Blade. The main blade characteristics are tooth shape and pitch. Depending on what part will be sawn, the appropriate blades with the size of the teeth are selected. Since few people pay attention to it in the home, it is better to take several different products
  • Cost. Price depends on quality and functionality
  • Manufacturer. If you like to choose tools strictly, then pay attention to models of famous manufacturers. A popular brand name in the hand tools industry is IRWIN

Such a reliable tool as a hand saw for metal, it is necessary in the household, so it is worth to take its choice responsibly and competently. After using the blade, do not throw it away, because it can be useful for making additional tools: knives, cutters, circulars and even chisels (provided that the teeth are not worn or blunted). Everything depends on the imagination of the master, so it is never too late to start implementing your ideas, and do not forget to share your inventions with others. The video tells about the proper operation of hand hacksaws on metal, which will also be useful and interesting to learn.

  • Metal file;
  • vise;
  • Drill or electric screwdriver;
  • screwdrivers and hex wrenches.

Materials for making a homemade machine:

Next, see the step-by-step instructions on how to make an electric saw:

We will need a wood hacksaw, or rather a blade from it, unscrew the handle.

To make our electric saw can make translational motion, it is necessary to make an eccentric. To do this, a washer, a bearing, a washer and a nut M14 is put on the spindle of the angle grinder. To offset the center of the structure, insert a piece of M8 bolt in the gap between the spindle and the bearing. It should be cut to the height of the bearing. The resulting structure is firmly clamped by the nut, so that the eccentric will rotate without friction on the thread of the spindle.

A similar design will be used to mount the saw, as on the standard angle grinder’s protective cover. We take a length of pipe equal to the distance between the beginning of the gearbox and the center of the eccentric bearing. Then it is partially cut into 2 rings. The cut must be larger than half. The line for the notch trimmer passes against the edge of the seating for attaching the hood.

To the edges of the cuts, a nut M6 is welded on. They will be used to tighten the ring like a clamp when tightening the bolt.

Then, in the saw blade, we drill a hole 1 mm larger than the outside diameter of the bearing. The top and bottom of the hole are bored out a little.

Cut out from the steel sheet, 2 equal rectangular plates of any size. A 40mm hole is drilled in the center of them.

One plate is welded to the clamp tube.

A 6 mm hole is drilled in the corners of both rectangles. They must be opposite each other.

On the blade of the hacksaw the holes are marked, as on the plates. They are drilled and then re-bored with a file to allow the blade to move. Grinding must be carried out horizontally both sides of the hole center.

To use the nozzle, it is necessary to grease the contact surfaces of the blade and the clamping plates with solidol.

Tighten together with bolts and nuts. Do not tighten too much. Locknuts are put on top to prevent the blade from unscrewing and clamping.

The eccentric is assembled on the angle grinder, and the head is put in place of the protective hood.

Makeshift hacksaw out of the angle grinder, ready to work! With this tool, you can quickly cut firewood or saw a desired piece of wood.

The accessory is detachable, so it can be removed for use as intended.

We recommend to watch video, where the angle grinder saw is shown in operation.
