- The right option is b). Foot-operated switches are more convenient because they act quickly.
- Theoretically. enough power in all three variants. In practice we use a) electric and b) pneumatic models. Battery is not necessary for a stationary grinder. For pneumatic drive a compressor with the appropriate capacity would have to be purchased.
- 900 W or more. Use correction if you intend to machine workpieces made of relatively soft materials or at high speeds.
- Both options are correct. Powerful angle grinder is suitable for a variety of machines domestic and semi-professional level.
- Two attachment options are permissible. Specialists prefer the top.
The electric angle grinder performs many different work operations. To reduce labor costs while increasing accuracy, it is used as the basis for the machine.
“angle grinder”. a common name for an angle grinder (angle grinder). By changing the disc, this versatile machine is converted for trimming, performing other work operations.
Why make a machine from an angle grinder
Cutting machine. it’s a useful and necessary thing and, not only in industry, but also in the economy. With this useful tool, you can make precise cuts of parts and workpieces. It is achieved at the expense of reliable fixation of a cutting disk, in a spindle of which not only abrasive circles for metal cutting can be installed. Stationary machine can be used for cutting tiles, bricks, marble, granite and other similar materials, using in the construction of the tool special circles with a diamond coating. If necessary, such a machine can be used to cut logs, boards and other wood workpieces.
On how to make the self-cutting machine from the angle grinder and improvised materials, want to know many who have not once faced the need to make an accurate cut of the workpiece. Holding the angle grinder in his hands, you can also make an accurate cut, but it is more difficult to do so, because the tool has to be held exclusively with two hands. With the help of a homemade cutting machine can not only perform, but also to simplify such work:
- Cut sheet material such as galvanized material used for chimney insulation and other applications
- Cutting ceramic tiles and tile. note that the cut can only be made straight
- Sawing materials at different angles
- To saw a metal profile, pipe, wooden bars, boards, etc.п.
To make a machine from an angle grinder requires an appropriate approach. After all, the tool itself is very dangerous, so the slightest miscalculation can lead to the fact that the master will suffer serious injury. About the consequences of working with an angle grinder in case of non-compliance with TB is known, so at first, before you build a self-made machine, it is worth noting the following:
- Only with the correct construction of the cutting stationary machine, you can be sure of its reliability and safety
- If planned to make, then it is necessary to calculate each step, so that in the process of operation there is no misfortune
- Using a machine is in some ways safer than operating a tool by holding it in your hands. However, you must be aware of the fact that the angle grinder is a mobile tool, and making self-made grinder is a violation of safety rules
- For the manufacture, it is necessary to use materials of appropriate reliability, corresponding to the power and size of the main power tool
Once you understand the need for making a machine, you can get down to business.
This is interesting!If you can not decide what is better. to buy a new machine or make it yourself, then the second option is more preferable, since in the independent manufacture will not need any costs, as the angle grinder is already in the economy, and the component materials can be found in the garage.
Types of mounts. in brief
Here are the fixing options offered by experts:
- With threaded mounts and a handle for control.
- Full fixation of the mechanism inside the metal shell.
- Fixing the angle grinder with clamps on the bed. Suitable for models with a small disc (no more than 15 cm).
- angle grinder and angle grinder with a circle diameter of more than 20 cm must be secured with a rotation axis, spring, frame and guide mounts. This ensures maximum reliability.
The model with the large disc
Rectangular profile base
The profile is a very hard billet, so the frame made of it will not be deformed in the process. On top of the frame-support is superimposed plane: either metal sheet or plywood (chipboard is also suitable). The wood must be sanded.
With carriage on shock absorbers
From round section pipes and a pair of shock absorbers you can make your own hands not a simple stand for the angle grinder, but a cutting machine that has in its mechanism a movable carriage.
Please note! To fix the slideways to the slide without damaging the shock absorbers, the tubes are very fragile.
Moving horizontally, it allows you to cut the material into longitudinal plates. The dampers can be replaced by a more complex rail design with bearings.
The carriage is an important structural element
Elements made of wood or plywood
However, if there is not enough metal stock, wood or any chipboard material can be used as a substitute. Even the lever, holder and other main elements can be made of wood, such as inexpensive birch or larch.
It is better to let plywood on the bed and the base of the product, while making the frame from a strong material that will keep it from deforming. The thickness of the material plays a key role in the strength of the structure: the thicker the material, the more durable it is.
Tool clamping options
Many experts say that there is no better way to secure the workpiece than the well-known vice. The use of this fixture ensures that the risks of injury are reduced to zero, even if the abrasive disc breaks into small pieces
Special attention should be paid to the rotary type of vice, at the base of which there are special longitudinal grooves. If a craftsman manages to make the correct oblique cut, then you can achieve a significant increase in the functionality of the device
First you need to prepare strong fasteners according to the drawings of the rack for the angle grinder. With your own hands you can build a unique fixture for the angle grinder, which must necessarily consist of such elements:
- Spring for counterweight.
- 2 tubes in the form of bearings.
- 2 meters of profile pipe.
- Sheet metal for a firm base.
- 2 screws.
You can build a rack from the most ordinary materials that can be found in almost every garage and private house. Of course, you just can’t do without a welder. Despite this, such a stand will not only be of high quality, but it will cost much cheaper than a purchased product. For more convenient use of the device its frame can be equipped with an ergonomic handle. In this case, a simple tube, which is fastened with a welding machine, will do.
A simple stand for an angle grinder
A very simple stand for the angle grinder can be made from just a few pieces of rectangular profile in a couple of dozens of minutes. And in the end you have a great cutting machine with which you can cut metal workpieces quickly and evenly.
Needed for the cutting machine
Mount them on a rectangular plate. The distance between them equals a little more than the thickness of the profile width.
To make the stand have more weight and be stable, we set it all on a rectangle of particle board. Of course, instead of all this, you could immediately take a thick steel plate.
Screw the steel base to the wooden base in several places, having previously made holes in the steel plate.
To attach the handle you must drill a through hole in all three sections. See
Drill two holes and mount the spring. If the lifting force proves to be insufficient. Enter another spring.
Now how to hang the angle grinder, it is necessary to make a hole in the handle of the profile. Try the angle grinder on beforehand.
At any time, the tool can be removed and used as usual.Such a stand will definitely come in handy. It will make it easier for you when, say, you need to make a lot of vertical cuts.Useful thing, minimum cost and time. the effect is obvious.Also on the modification it will not be superfluous to make a limiter of movement downwards. Thank you for your attention!
Advantages of a pendulum saw
- Angle grinder;
- Electric jigsaw;
- Drill or bench top drill press;
- Epoxy glue;
- Welding machine;
- Wrenches, pliers;
- A tape measure, a pencil.
Bed and moving shaft
The author has chosen an excellent material, textolite, as the base. It does not catch fire, will not warp under the influence of temperature and is absolutely moisture-resistant. Two sheets of textolite are spliced together with epoxy resin and bolted at the corners, which in addition act as legs for the machine.
For the movable shaft of the lever the axle from the bicycle slide is suitable. This part has lugs that are used for positioning the bearings. To secure the bearings on the bed you need two clamps. They can be made from any suitable width of metal strip.
Using clamps, bolt the movable shaft with the bearings to the bed. It is necessary to prepare (grind out) the middle of the shaft axis for welded connection with the lever plate. It will be reinforced later on with reinforcing ribs from a small piece of metal.
Making the lever for facing
We make the lever mechanism from a profile pipe. This molding is convenient because it has a strict edge and regular shape in the cross-section, which means that it will be easy to maintain an even path of inclination of the angle grinder.
The curved part is equal to the size of the gear head of the angle grinder. We cut it with the angle grinder and weld the corner joints. It is also necessary to make holes for fixing the tool. Since it weighs a lot, the holes for mounting bolts must be from all three planes that the angle grinder adheres to the lever.
The final element will be the plate, placed at right angles to the axis of inclination of the lever. The handle of our face grinder will be fixed in it.
We weld the adapter plate to the end of the arm and fix it on the shaft. At the opposite end of the lever mount the handle.
Return stand, stop bar
The return mechanism of the arm on the pendulum saw is performed by various spring mechanisms. In our case it will be very simple variant that consists of a rod and a spring stretched on the lever. We cut a thread about 5-6 cm deep into the end of the metal rod. Screw the nut as far as it will go, put a washer on it and tighten the stand on the bed almost close to the bearings so as not to weaken the spring. We clamp one end of the spring with two nuts on the rod, and clamp the second end to the welded nut on the lever.
To place the workpieces more securely on the base, it is necessary to make a thrust strip. We make it from a small metal angle of 30×30 mm. Fix it on one bolt at the very edge of the cut left by the angle grinder to mark its working border on the bed. This attachment will allow you to change the facing angle relative to the workpiece stop in this bar.
For fixation of the second end of the stop it is necessary to make a hole for bolt connection. Mark the trajectory of the slat along the arc by the hole. Drill a hole for the jigsaw and make a groove with the jigsaw of the width equal to the free stroke of the clamping screw.
Making the main parts
So, let’s describe the process of assembling the bed step by step:
The main difficulty is the device rotary lever, which must reliably fix the angle grinder and ensure that it turns at 90 °. For this purpose you can use metal angles or profile pipes with bolts screwed to them in two planes, which will provide clamping tools.
To make the swivel device you can take three connecting rods from an old car and a pivot pin. This device will be free of backlash and clearance, and the pivot axis will run parallel to the plane of the table, ensuring accurate cutting. Although you can also assemble a swivel arm from standard joints.
Swivel arm assembled from connecting rods and axis pin
Old springs of the right size will ensure smooth movement of the swivel arm and return the angle grinder to its original position.
To ensure that the swivel arm stood precisely at right angles, we put a locksmith’s corner to the already assembled structure, and with the help of an assembly tool slightly bend the connecting rod mechanism.
Using a locksmith’s angle, align the swivel arm exactly at right angles
To ensure the free movement of the tool in the table we make a cut of the required size with a cutting wheel of the greatest thickness. If necessary, it is refined (expanded and extended) with a small angle grinder.
Precise cutting of parts at 45 and 90 degrees can be achieved by screwing the steel angle to the work surface. To do this, we put the disk in a slot and mark the location of the holes for fastening. By changing the position of such a device in relation to the saw blade, parts can be rotated at different angles. To get the mirror angle of 45 ° need to prepare a hole, which will be relative to the drive at 135 °.
Holes for mounting the angle at 45, 90 and 135 °
It is possible to attach a movable ruler with a stopper to our bed. In this case the products can be cut as precisely as possible.
For convenience of work to the vertical bar, which clamps the angle grinder, on the side opposite the disk will also need to attach the handle. You can use a long bolt with a plastic tube slipped tightly over it as an angle grinder.
To check alignment, we insert an angle grinder into the table and manually turn the disc several times. If there is no beating, switch it to low rpm and try to cut the wooden workpiece. If the tool starts to vibrate, find and remove the cause.
It is better to make a remote on/off switch, because the hands of the worker are always busy. In this case we use the magnetic starter attached to the foot pedal.
Making a removable cover
To increase the safety of the device and protection against sparks to the angle grinder is better to make a cover of galvanized tin or metal housing of the old equipment. It can also be welded from thin metal.
- To avoid mistakes, we first make a template from cardboard.
- Using it, cut mirror reamers.
- To keep the rivets from interfering with the grinding wheel, rivet the fastening corners from the inside.
- Fold up and rivet the two halves of the hood, mount them on the clamping rod, and prepare the tapped holes for attachment.
Angle grinder is considered one of the most indispensable tools in many industries, as its areas of application are quite extensive. The versatility of this machine allows you to sand, snip, cut and even polish various surfaces and objects. Every man can independently make a quality stand for the angle grinder, thanks to which you will be able to cut any workpieces with perfectly smooth edges without any hassle.
Always remember that the stand must be firmly fixed to the bed. To protect yourself from injury and accidents, you need to follow the basic recommendations:
- The power cord is best secured with plastic clips, so that it does not get tangled under your feet and accidentally fall under the cutting tool during its active use.
- The cable from the angle grinder must be attached firmly to the mobile part of the stand.
- During operation, it is advisable to use special goggles to prevent microscopic particles of metal in the eyes.
- Before you start the machine, you must carefully inspect the cutting wheel of the angle grinder for chips and damage.
Today there are many protective elements that can be made even at home. As for the optimal size of the stand, it is better to give your preference to those models that fit the diameter of the disc used. All parts of the frame must match the brand of the angle grinder used.
Experts say that it is good to work behind the pendulum stand, which simplifies the very process of sawing metal workpieces. In addition, the pendulum system is arranged in such a way that with its help tasks of any complexity can be quickly and qualitatively. To make such a device at home is simple enough. For this you need to take: a quality metal profile, a spring, a welding machine, a pendulum and corners.
Particular attention should be paid to the iron table, on which most often masters install the construction created by them. It must be tested for stability, reliability and wobbling. In addition, in the process of making even the smallest parts of the stand, you should not forget about safety measures.
Advantages and disadvantages
Making a stand for an angle grinder with your own hands provides a number of advantages. These can include:
- The ability to create a product with the necessary dimensions;
- The person himself chooses the functionality of the created machine;
- Such a product has sufficient strength;
- the possibility of misalignment of the cutting wheel and its deformation is excluded;
- the design is easy to use, fully meets the desired performance characteristics;
- all the work is done with minimal financial outlay;
- the angle grinder can be removed at any time and returned to mobility.
Such a product allows you to perform the necessary functions with the utmost precision. Fully meets the safety requirements.
Its disadvantages should include the lack of control over the work performed and its quality. Consequently, all actions must be carried out carefully and strictly follow the calculations and drawings.
Instructions for making a homemade stand for the angle grinder:
Cut to size and weld the profiles into a frame with the approximate size of 350-500 mm. This will be the base of our stand.
Assemble the bracket for fixing the angle grinder. Marking and drilling 10 mm holes. in a profile and then saw it to size. Let’s mount these profile pieces on the angle grinder and weld the profiles.
The next step is to cut two profile pieces from which the stand itself will be assembled for the angle grinder. The length of the profile is approximately 30 cm. Drill a hole in the center of the profile to install the hinge in it.
Assemble the hinge of bolt M10 length 150 mm and install it in the pre-drilled profiles, while ensuring the free rotation of elongated nuts.
Weld the elongated nuts to each other and check their free rotation on the bolt.
Cut two more pieces of the profile, the length of which is chosen individually for the size of the angle grinder. They will be a lever.
On the cut profile pieces we mark outline of elongated nuts and accurately saw outline on profile ends for more reliable welding profile.
We weld these profiles to the lengthened nuts. Fasten profiles with clamp to keep parallelism and accuracy of installation.
We weld the rack with the lever on the hinge to our base.
Connect the arm of the rack with the bracket attached to the angle grinder with the help of specially prepared angle bracket with longitudinally sawed holes that will allow you to deflect the angle grinder’s disk in the plane to set the exact angle of the cut.
Then we take out a standard bolt from the handle of the angle grinder and insert the elongated bolt that will pass through our bracket and it will reliably fasten the bracket with the angle grinder.
In the frame-base we weld two pieces parallel to the plane of the wheel of the angle grinder, they will serve as a support for the cut parts.
Level the angle grinder on the disk and the base through the angle grinder and screw all bolt connections securely.
Weld two more pieces of the profile in the frame-base, they will be guides for the bolt of the angle grinder.
Add two more pieces of profile in the frame-base that will serve as a support for the swivel angle fixing bolt.
In a swivel angle we saw a longitudinal hole that will allow you to move the angle on rails and in the right place to fix it with a bolt.
Weld bolts with rounded heads to the frame base with which you will be able to adjust the horizontal level of the base frame.
We drill apertures in a bracket attached to the angle grinder and in the upper part of the stand. Secure the steel hooks in them.
We measure the necessary length of the spring, and having previously cut it, fix it on the hooks, so that it will return the angle grinder to the upper position.
Make a test cut. We check the cut piece of the workpiece for the correct angle.
Selfmade stand of the angle grinder is ready. Now you will not have problems with sawing workpieces at any angle.
Note: all welds and sharp corners of all parts of the stand should be cleaned and rounded. Prepare the stand for painting and paint in any color you like.
The device for the angle grinder of the pendulum type can be easily created by your own hands. The main elements of construction:
- Support or bed. the part from which the vertical bar departs and where the workpiece is placed for cutting. The support part also performs the main function. holding the entire machine in a stable position.
- A vertical fixed stand, or tripod for the angle grinder. this structural element is part of the pendulum mechanism and supports the mobile console.
- The sliding bar or console is the part to which the angle grinder is directly attached.
The support part is mainly made of sheet metal. As it can be the factory base, for example from a drill press or any other, where there is a flat platform. On the bed for the angle grinder, there must be a guide, where the pipe rests during cutting. The guide plate prevents the workpiece from moving during the operation. In addition, for more convenience, you can equip the support with a clamping mechanism that will firmly fix the pipe to the guide during the work of the angle grinder.
The stand, or tripod, is a vertically going up element. It can be made of square or round tubes. In the upper part there is a bearing unit for the movable connection of the stand with the pendulum arm of the angle grinder. The height of the stand depends on the size of the angle grinder and the pendulum device. Type of tube (its geometric parameters and wall thickness) chosen according to the power and weight of the power tool.
The pendulum bar of the angle grinder performs two functions. It holds the angle grinder firmly in place, thereby preventing axial movement of the angle grinder. Secondly, it is used to feed the tool into the working area, i.e. the angle grinder can lower into the working position, make a cut and return to the starting position again. There is also a special handle on the console for operating it.
Counterweight design with shock absorber
An important part of the angle grinder bed is the counterweight. This design element performs a completely specific function: it returns the angle grinder to its original position when the operation of cutting metal is completed
If you don’t have a counterweight, it will be very difficult to work with the angle grinder. Before installing the workpiece, it must be lifted and held on your hands. The angle grinder also has to be turned on by weight, which is not safe. Counterweights come in two designs:
- Traditional type. It is done by installing a weight on the tail of the cantilever bar. The weight of the load is selected so that in the initial position the angle grinder was at the top, but when lowering it to the workpiece did not have to apply great force.
- A spring mechanism as a counterweight. In this case, in the upper position, the angle grinder is held in place by the elastic force of the spring. The most suitable for this purpose is the door leaf closing spring.
A shock absorber or stop is also necessary in the design of the stand for the angle grinder. The main purpose of such an element is to prevent the tool from moving down below a certain level. At the moment when the pipe is completely cut, the lowering of the angle grinder must stop.
What advantages and disadvantages are the advantages and disadvantages of homemade machines from lathes
There are some advantages and disadvantages in the considered self-made machines, which also need to know about everyone who set out to make a cutting machine from the angle grinder. The advantages include:
- Having a stationary machine in the garage, you can quickly, and most importantly qualitatively cut different materials
- Achieve a quality and even cut, which makes the device perfect
- Cheapness. if there is an angle grinder, the cost of making the machine will be minimal
Now let’s find out what are the disadvantages of the considered homemade device:
- Low reliability. even with the most competent approach, it is not excluded the possibility that a person can get different injuries just because of work on such homemade equipment. To protect yourself, you need to work in protective gear
- The complexity of transporting the device. it all depends on its size and weight. Only if the machine is called stationary, then it is designed for use only in one place
If you have already managed to produce the type of equipment under consideration, then it will not be difficult to understand the correctness of its operation. Already at the first test of the tool you can feel how effective its work is. Below is a selection of photos that show options for self-made cutting machines from grinders. There are also plenty of other interesting ideas for extending the functionality of such a tool as the angle grinder, but that’s another story.
Sawing-off attachment for porcelain tiles
When tilting the attachment, you can easily check expensive material. It is expedient to use special machines for exact correction of fixture movement. From an old angle grinder it is possible to make the necessary mechanism.
This technique requires the installation of several rails on the platform, with subsequent movement along the conceived trajectory. Also, a homemade device will allow you to change the cutting angle and depth of treatment. To create a machine for porcelain tile will require proven drawings and experience.
