Angle Grinder Stand Angle Grinder for Stationary Cutting
Materials and tools
The first question that a home craftsman faces when designing a stand for an angle grinder is what to make it from. The answer to this question is elementary: we will do what we have. If you have water pipes on hand, they will come in handy for making hinges and guides. If there is a metal corner, we will assemble a frame from it.
The main and most complex part of the pendulum saw is the hinge assembly. It carries the greatest loads, while the pendulum arm should not be able to freely deflect to the left or right. Consider the design of this node with the greatest care. Roller bearings are ideal. Pick a pair of suitable sizes. and already “around them” build the rest of the structure.
It is best to mount the pendulum arm on ball or roller bearings. This will provide the best precision and rigidity. But if there are no suitable finished products, it is quite possible to spy on the options for homemade designs of this unit.
If there are no ready-made bearings, match pairs of metal tubes and steel pins of suitable diameters. This will make it possible to make not too high-quality, but home-made bearings. For a “plywood” machine as a suspension of the pendulum arm, good canopy hinges used for fastening doors and gates will do.
In any case, the pendulum arm itself is best made from a metal corner or metal profile. But the holder, in which the angle grinder will be fixed, will probably be made of a wooden bar.
For a secure and tight fixation of the angle grinder in the holder, it is better to glue the stock with a soft and durable material. For example, leatherette. And it is most convenient to press the angle grinder to the holder with flexible metal ties with a screw assembly. These are widely used in plumbing and car service.
The bed is best made from a thick sheet of metal. Compromises are possible, up to thick plywood fixed to a timber frame. It is good to provide on the desktop the possibility of fixing the abutment corners at some standard angles to the cutting axis. Thus, we get a “miter saw”.
Do not forget that you will no longer be able to control the turning on of the angle grinder on the machine in the usual way. We can replace the operator’s hand on the control keys with the same screw ties for pipelines. But the keypad control post (which we will fix on the bed), a socket for connecting a fixed angle grinder to the circuit and a wire with a plug of sufficient length to connect the entire machine to the network should be saved.
If we have metal blanks at our disposal, it is best to connect them by welding. If you do not have such an opportunity, it is better to contact the familiar masters of this business. Bolted connections loosen over time and negate all the advantages of a metal frame.
Of course, the angle grinder itself will come in handy in the manufacture of the machine. Cutting with its help blanks for the rack, you can feel like Munchausen pulling himself out of the swamp by the pigtail.
Very stiff in itself, this profile allows for a rigid and sturdy frame. importantly, the pendulum arm made from this material will barely bend during operation.
But the bed frame is only half the battle. On top of the frame, you need to put a “tabletop”. a plate on which the processed material will be placed under an angle grinder.
If the frame is made of metal, sheet metal is the best material for the workbench. However, a thick sheet of plywood or chipboard is also fine. Just do not forget that a fairly wide slot must be provided in the tabletop directly under the disc of the angle grinder in the table top, which provides a through passage of the disc through the material to be cut.
The upright is a very busy pendulum saw unit. The use of a metal profile will create a strong and rigid structure.
When using metal as the basic element of the machine, preference should be given to welded joints. Of course, metal profile products can also be bolted together.
But such connections do not provide the required rigidity.
Making a stand for an angle grinder with your own hands
Angle grinders (angle grinder) are an indispensable hand tool. With their help, you can saw, grind, cut almost any material from wood to stone. But often there are tasks that require the use of a machine park.
For example, when cutting pipes, a profile or a metal profile, it is quite common to cut a long string into segments of a certain length. In this case, it is important that the ends of the segments are strictly perpendicular to the axial mowing line.
When cutting tiles or bricks, it is even more difficult to keep the cut square by holding the angle grinder by hand. When cutting thin and sticky material, the slightest deviation of the tool from the mowing line of the cut can lead to jamming and breakage of the tool.
In such situations, it is quite natural to desire not to buy a separate machine. this, as a rule, is economically impractical.
You can expand the scope of your favorite hand tool by rigidly securing it in some way.
Honestly, the do-it-yourself racks available in many designs should rather serve as food for thought. It is worth taking a closer look at the design, typical dimensions of standard elements and general design principles. Then apply them in our particular case.
The fact is that the dimensions of the structure and individual nodes will entirely depend on what you have at your fingertips. For a large angle grinder (eg 230 angle grinder), you may need to make a holder larger than shown in the drawing. This will entail the need to replace bearings and so on.
How to Make Angle Grinder Stand. Angle Grinder Attachment.
The general principles are clear enough. The simplest and most commonly used machine is the transformation of a hand-held angle grinder into a stationary pendulum saw. This design consists of a bed, a stand and a pendulum arm, which is hinged on the stand.
Consider manufacturing options depending on the materials available.
Carriage made of pipes and shock absorbers
If there are water pipes, a pair of car shock absorbers and a metal corner or profile in stocks, you can make a wonderful facing (aka “cutting“) machine with a transverse horizontal carriage feed.
The pendulum unit is still required to bring the tool into the cutting plane. But the carriage, movable along the pendulum arm, allows you to significantly expand the range of material sizes. Now you can cut quickly and accurately not only pipes, profiles and beams.
The horizontal carriage travel allows you to neatly cut sheet materials as wide as we can design the carriage overhang.
Complex rail assemblies with spring-loaded bearings are usually designed to ensure smooth yet accurate carriage travel. But you can use car shock absorbers. They have a very robust and precise construction. If you remove gas and liquid, you get excellent guides.
The rear shock absorbers of VAZ cars have a stroke of almost 200 millimeters. This will allow, for example, when attaching an angle grinder-230 to a carriage, to organize a cutting line up to 400 mm long. But even if you have a compact angle grinder with a disc only 150 mm in diameter, you can still cut sheets up to 200 mm wide. This more than covers most everyday tasks.
When designing the “guide-carriage” assembly based on automobile shock absorbers, it should be taken into account that the shock absorber bodies themselves are quite thin and easily wrinkle. Such “guides” should be fastened to the upper arm of the pendulum with semicircular clamping brackets. This is where water pipes come in handy.
An interesting solution to the problem of stiffness can be the use of plywood in a wooden structure. The multidirectional veneer layers in this material impart a certain dimensional stability to plywood products. The fact that the product consists of many thin layers, connected with a strong adhesive, provides strength.
Plywood is great for making beds and work tables. When designing, it should be borne in mind that plywood is very strong and stable in the plane of the product. But the plane itself can be deformed. Therefore, plywood products should be mounted on rigid frames.
A good example of a design is a multi-layer plywood assembly with intermediate bonding and bolting.
The result is very strong, rigid and stable structures.
Elements made of wood
If it is not possible to make the basic elements of a pendulum saw from metal, do not despair. Many structural elements can be made from wood. First of all, this is the bed, pendulum arm and angle grinder holder.
The frame can be made from any suitable lumber. Frames made of solid and heavy timber of significant cross-section are very good. They are both durable and quite heavy. This ensures the stability of the entire machine.
The frame, assembled from an oak bar with a section of 100×100 mm, is certainly impressive. But it is too expensive. Thick bars of larch or even birch are quite suitable for the base of the desktop.
But for the manufacture of the pendulum arm, you can just use the noble types of wood traditionally used in furniture production. Oak would be quite appropriate here.
When constructing a machine from wood, do not forget about the overall rigidity of the structure. Significant dimensions of the bed make it possible to ensure the strength and rigidity of this part when manufactured from not the highest quality materials.
The pendulum arm has a long, elongated design. If made of wood, its geometry can be unstable with changes in temperature and humidity.
For this structural element, it is better to use the so-called furniture board, consisting of several wooden elements glued together.
Stand for Angle Grinder with Broach Beking BG-612506
Angle grinders (angle grinders), usually called “grinders”, are probably the most widespread both among home craftsmen and, naturally, at service stations and other large and small industries. But, since this is not a stationary tool, but a manual one, to solve problems with precise fastening of workpieces and error-free production of more accurate cut by grinders, modern “kulibins” have always tried to make various devices. And more recently, many manufacturers of power tools have begun to produce factory stands for an angle grinder, constantly improving them to be able to work with grinders of different sizes.
Now, the most functional, universal stand for an angle grinder from the Beking company, which has proven itself only from the best side. model BG-612506, has appeared on the market. With this pull-through stand, you can easily transform almost any of your angle grinders into a small cross-cut saw for metal, wood, etc., with the ability to make precise and accurate cuts.
Homemade Angle Grinder Stand / Angle Grinder Support.
A feature of this model is the fact that the sturdy structure of the block (in which the angle grinder is installed) can be moved along an axis perpendicular to the cutting axis of the saw blade. Naturally, this structure can be fixed in the steel base of the rack in the required position to accommodate a wide variety of models with different maximum cutting wheel diameters. over, almost all angle grinders can be fixed in it, starting from models with a circle diameter of 115/125 mm, and ending even with some models with a circle diameter of 180 mm. In the case of the latter, the distance in such grinders between the holes for the fastening bolts should be no more than 85 mm. this is a technological feature of this particular rack. To do this, the rack is equipped with bolts of different diameters, and these bolts themselves are attached to a certain model of an angle grinder through special adjustable rails installed in the mounting block of the rack.
To align the cut-off wheel ideally at 90 ° to the base of the stand, the unit is equipped with adjustable set bolts with rubberized heads. They allow you to carry out this procedure, which is responsible for the subsequent safety of the master, as correctly as possible.
Also, the handle, which the operator uses during operation, has two landing holes for the most convenient positioning with different models of grinders.
The main advantage of this modernized stand is that it has horizontal guides along which the block with an angle grinder moves (the movement resembles the broaching system of most models of stationary miter saws). Thanks to these guides, it becomes possible to cut workpieces of much larger size than would be possible with conventional grinder stands. These include the Forte AGS 125, in which the cutting and sawing process (with the help of an angle grinder fixed in it) occurs due to guided lowering only directly in one place. Because of this, of course, it is impossible to cut workpieces of a larger size than the cutting part of the disc of a particular model allows.
The clamping vise for fixing the workpieces, located on the contact pad at the Forte AGS 125, is also very similar, but not quite the same. In the Beking BG-612506 model, they have a more advanced quick-clamping design: by pressing the locking button on the vise body, the movable jaw can be moved to any desired length in one second. After that, pressing the workpiece as tightly as possible, you need to release this button and complete the fastening, slightly tightening the screw guide of the vice for reliability.
Both jaws of the vice (movable and fixed) can be adjusted to set and fix the required cutting angle up to 45 °, and the thickness of the clamped part can reach 10.5 cm.However, the free play of the angle grinder along the guides is 145 mm.
