How to make a bracket for an angle grinder

How to make a bracket for an angle grinder

Stand for angle grinder (angle grinder) with their own hands or self-made cutting machine

As I said before, in the garage there are two problems. to cut off evenly and to drill evenly. The problem with drilling solved, the drill stand was worth all the time and money. Long dusty in the corner waiting for his hour angular grinder. That angle grinder. made back in 1977. In Bulgaria, the “ELPROM LOVECH”, terribly heavy, but, according to rumors, very reliable angle grinder. I tried to work with it. I thought I was if not a tough guy, then I’m sure I’m experienced. Always worked a big Makita 9069, the thing is pretty powerful and heavy. But the angle grinder in comparison with makita. a wild beast. With similar to makita power 1.9 kW it is significantly heavier, in addition, mine specifically for 180 mm disks and output speed of 8500 rpm. In general, I then decided that in the hands of her no longer take it (peskotno) and the way it is only in the rack. And I wanted to make a rack a long time ago. And of course the stand should be as usual. “light, strong and reliable”. I’ll tell you right away, the only justification for the work done. “well, it’s for myself, for many years, a good tool is not easy”.

Started out like everyone else. welded a rectangle for the base.

For hinge was taken the rear hub, I think from Chery Tiggo. I cut off its central ledge, removed ABS sensor.

To mount hub to the channel, in which I cut out a hole for mounting. Cut it out with an angle grinder, it is pretty hard by the way. I finalized it with a file.

I started to make the main bracket for the angle grinder from the angle grinder itself. First, I matched corners to regular places of fixing handles, then I welded third corner between them.

Then I bent the bracket. clamp on the body of angle grinder of 2 mm steel.

To this clamp welded a bolt and connected with an angle piece. To all the resulting structure welded a 50X50 tube with holes for mounting to the hub.

Use the bolt to adjust the position of the angle grinder relative to the table. Next, I welded a 60 angle to the base. it will be used for fixing the channel. I estimate the position and drill the channel and angle under it. Mounting bolts will be different. M10 and M12, this is due to the second adjustment, the channel should rotate slightly at the expense of larger holes for the bolts.

Then I welded two more pipes. guides for clamping mechanism, and also reinforced construction by two parts of 50th angle piece.

Next, on top of all that I welded plates with thickness of 4 mm. No matter how I tried I failed to make the surface perfectly flat, there are 1-1,5 mm differences, but in practice it doesn’t influence the cutting accuracy.

Making Angle stand For Grinder DIY

Now we can assemble the setup. I additionally reinforce the channel and the main bracket with angles. The total weight of the installation is not critical yet, but already quite interesting.

After that was the longest and most laborious. rigging for work. This is the workpiece stop and clamp, this is the return spring and this is the table expander. Let’s start with the stop for the workpiece. We take a piece of 50th angle, weld a small rectangle to it.

Now I had to cut an arch in it, so I could cut the workpieces at any angle. Use the template to drill the holes in the arc first. Then I mill the arc completely.

Now the clamping device. The screw was taken from an old and bent eighth jack. I figured it would be better than a normal Chinese threaded rod. I ground the end of the screw to 6 mm and cut the thread.

For the moving part the most difficult thing was to make the axle. I made from a piece of the same Chinese stud, I’ll tell you right away. I didn’t use a lathe, I ground to the right diameter with an angle grinder, even with some tools.

Now we have to fix the nut. The clamping device was supposed to be detachable, that’s why it is bolted, and the threads are cut directly in the table. The jack nut was welded with 4mm pieces of steel.

Since the clamping device was ready, I decided to cut the pipe for the legs of the table to see how it all works. As a result I made a cut on the stop of the workpiece. the gear case of the angle grinder rested on it. Also later trimmed the clamp to the width.

By the way, you can see the wing nuts in the photo. I worked with them one cut. Never use wing nuts in those places, the manual force is not enough to hold the stop well. It’s an invaluable experience. the nuts are loose, the disc is blown to shreds. Now it’s regular nuts, I always tighten very tight.

Then the return spring. Like a spring I thought it would be a spring, but it ended up being something cooler. I know I made it difficult, but it was worth it. I imagine how strong the spring is to hold the angle grinder and the effort at the end of the cut should not be small. In addition, after the cut you have to move the angle grinder smoothly upwards. I wanted to cut and release it and it would go back to the original position FASTERLY by itself. What it takes? The gas stop, of course, is from a nine-year-old, on the shelf. And another thing. the return system should be hidden, that is to work from below. That means you need additional rods and levers. Actually it is quite easy to do, I would even say fast. First, I made a cut in the table for the lever. The lever itself made from a corner, by a lot of trials gave it the desired shape. It is fastened directly to the hub, to OEM stud.

We need some more details. the gas stop proper, long rod to it, collar bent from the stud M6. The stopper is how it was. It worked the first time. At first it seemed to lift a little, but when the angle grinder got all sorts of handles and the hood, it turned out just right.

Parts of the return mechanism. Mechanism in a squeeze/unclench position.

That’s almost all. I also made a spark arrester. just a tin screwed on the path of the sparks. I also put a separate drive handle. I screwed the tube to the main bracket, and to the tube. the regular side handle of the angle grinder. Of course I made the extension of the table, on the tube-in-tube principle. Here was the problem, there was a 45X45 pipe inside the 50X50 pipe. It exists in principle, but in fact it is nowhere to be found. I had to weld 4 mm strips on a 40X40 pipe. On the expansion will always be two of the device. an additional stop workpiece. is needed so that the cut portion was not picked up by the drive and did not fly away, and an additional stop for “cloning” parts. if you need two or more parts of the same length do not need to measure the length of each cut.

Extension of the table and fixtures on it.

Yes, I forgot about the blade guard. The original cover was long lost, it was under the 230th disc. I’ve increased it where possible to the maximum and made to it a hinged part, like on the factory assembly saws.

The main stages of the work

In the next step, the author attached two furniture rails to the plywood workpiece. Then it had to be attached to the platform, which is on the base.

After that, to the workpiece with the rails using a hinge, the craftsman fastens another piece of plywood, to which the angle grinder will be attached.

Next, on the side of the two plywood blanks, which are connected with a hinge, you need to screw the spring. In a small workpiece, two holes must be drilled for the fastening screws. Then the angle grinder itself is attached.

In the end, you only need to make two stops for the workpieces: one perpendicular and one angular.

The base for the angle grinder and the holder, a device for the stand with their own hands

If you take into account the vibration and backfire, the stationary installation, of course, in the work is more stable. But buying a machine for industrial production can not be used for its intended purpose at home. So the simplest machine model will cost about 22,500.

Angle grinder attachment

But such equipment, there are also some disadvantages, which can lead to the idea that it is easier to create a cutting machine using a bed and just an angle grinder. Factory-made models of such machines are limited in their use. For example, the model discussed above, can cut only 100 mm pipes. In the domestic environment, however, it is very common to work in conjunction with samples of a higher quality section. In addition, everyone has their own needs, so a certain model simply can not fully meet them.

Factory devices can be significantly modified, but most often this is done in conjunction with a financial investment. In some cases, it is irrational and wrong to make changes to the appliance at all.

This will apply to equipment that is created from alloys that are difficult to process. Machine from the angle grinder created by yourself nowadays very often home masters try to create.

In order to perform such a task, it is possible to use several methods at once. If you look at them in detail, you can come up with your own design.

Blueprints cutting machine from the angle grinder

Before you start the work of creating a machine from the angle grinder, you should prepare additional components and parts, which can be pipes or angle grinder, which will act as a handle and frame. It is best to strengthen the angle grinder on it, using a special metal plate for this purpose. To create such a workpiece, you need to use a thick piece of iron, and it will take you about 30 minutes to make such a device.

The metal sample will be used as a support, it is best to weld an angle to such an object. The end of the lever should be installed on the axis, because the return stroke will be made with the help of a spring.

If you create a cutting machine with an angle grinder yourself, you can as a result get the equipment with a small weight, which can later be placed absolutely anywhere.

In addition, the assembly of the device will not be a significant expenditure of funds, because all the necessary parts can be found in everyday life.

The second way to create a machine

Creating a machine with the use of angle grinder by this method will be a little more complicated, but the tool will provide a more efficient accuracy of cutting materials. To carry out the work will have to create:

The frame of the table should be welded from angles and channels. As a tabletop, you can use a special sheet metal, but in some cases use materials such as:

The decision about what material to use when creating it will directly depend on the purpose for which you want to apply such a device, as well as with what circuits in the future you will work. In the process of creating a machine from the angle grinder by this method, you must also create a frame structure, one part of which will be completely immobile and will serve as additional support.

One part should be placed on the table top and fixed firmly with special bolts and welding. The second construction will be connected to the first one by hinges. On it will be installed itself angular grinder, the position of which is easy to change yourself. To return the equipment to its initial state, you need to use a special spring.

If you will create a cutting machine from the angle grinder, you also use a ruler to create it. With the help of a ruler you can easily expose the overall dimensions of all samples. For this purpose, most often a separate tube or iron with marks and a movable marker is used.

What should be taken into account

A special cutout is made in the angle grinder on a special line of the disk adjoining the table top. If you have any knowledge of electrical engineering, it is worth turning on through a special magnetic starter, in which case the start button will be combined with a specialized pedal. Even when the operator’s hands will be busy, the machine will in any case be able to stop with the foot.

During the creation of a cutting machine from an angle grinder by yourself, the drawings should be considered very carefully. Very often they help not to make unnecessary mistakes in the design of the device.

It is very important to observe all safety rules. At the moment when the assembly of the machine is finished, it should be run again, which helps to finally make sure that there is no runout of the disk itself.

It must not touch the machine guard.

Alternative to building a pendulum type machine

If the machine will involve load-bearing platforms, the sheet steel must be fully cut to its dimensions. To the lever, which looks like a piece of profile pipe, it is worth attaching a cross cut by welding. At this time it is worth following the perpendicularity of the attachment.

Features of using the angle grinder as a saw

It is worth remembering for your safety that not all types of discs can be used directly for the angle grinder. First of all, this applies to discs for wood sawing, which have significantly lower RPMs than are used in almost all grinders.

Exceptions are special wood discs, designed for the standard RPM of angle grinders.

It is good if your tool has a RPM control. And if not, then before you use your angle grinder as a cross-cutting saw for wood, make a simple regulator of its speed on the basis of chip KR1182PM1, or close to her on the indicators, according to this scheme.

You should not use a simple rheostat for this. Together with decreasing RPM, it will also proportionally reduce power and torque of the tool. And for the most angular grinder to use in such modes of operation is harmful.

We strongly recommend to provide your stand with a button for emergency shutdown of the tool, because access to the shutdown button after installing the angle grinder in the stand can be difficult. And even a securely mounted angle grinder in the device. a tool is quite dangerous.

You can put such a button in the cut of her power supply wire, but it is better to break it supply electric mains, because the angle grinder, removed from the stand, becomes the usual mobile tool with all its advantages.

The essential steps

The first thing is to make the shield. for this we cut two rectangular pieces of plywood and sheet metal with the dimensions of approximately 40×60 cm (in this case the dimensions are individual, you can make a wall shield for angle grinder with discs larger or smaller). The sheet metal is attached to the plywood with two-component glue.

From the remnants of sheet metal cut two identical plates, which are made seats for the angle grinder. for this we bend them on a sheet bending machine or in the vise of the beech “P”. In the boxes we make hemispherical notches and drill holes for fastening to the stand.

In the next step we fix the U-shaped plates at the bottom of the wall plate, and then make and install the hooks for the circles and the key from a steel bar. Paint all the parts, assemble the shield, and hang it on the wall. Now the angle grinder and its disks will always be at hand.

Precautions

Welding, sawing, drilling. all this involves working with electric tools. That is why basic safety precautions must be observed: do not work in wet areas, and protect your eyes and hands from sparks and crumbs. If the saw table is taken outdoors, then it is necessary to build a shelter over it. it will protect the machine from snow or rain, and the metal and wooden elements will not rot or rust.

To work with the machine was safe from the very beginning, this should be taken care of at the stage of its manufacture.

  • First, every angle grinder or angle grinder has a cable. It must be attached to the fixed part of the makeshift holder. Plastic broaches can be used to secure it.
  • Secondly, the connecting rod, as well as other parts of the construction, must be proportional to the size of the angle grinder. The table, supporting the product, must be stable and strong to avoid falling and, consequently, injuries to the master. The homemade angle grinder stand is attached to the table using a vise.

Important! Before you start, make a thorough inspection of the wheel to be sure it is intact.

To increase the efficiency of the cutting unit, it is preferred to fasten it: thus a convenient cutting angle is fixed, the master facilitates his work, and also insures himself against accidents. Wondering how to make a stand for the angle grinder itself, some fear that it will come out costly in terms of materials and efforts, but these fears are unfounded. For the construction it is enough to use improvised materials, which every amateur has in his garage (wood, plywood, profiled pipes and water pipes, metal profiles). Basic skills in welding and repairing work will be enough to assemble a working unit.

Homemade stand for an angle grinder

This is probably the most useful machine for the garage. Of course, if the garage is used not only for storing the car. There is a lot of complicated work in it, but it is worth it.

Mark the edges at an angle of 45 ° and cut off.

We form a square, tack weld on each side and then all the seams are welded.

Grind first a simple wheel, and then a petal.

We make the legs out of a 30×30 pipe. Hold them in position when welding will help magnetic angle.

Two pieces of pipe need to be tapped and drilled with a diameter of 10mm.

On one side of the square find the center, at an equal distance from it we will fasten the legs of the stand.

WOW COOL IDEA FOR ANGLE GRINDER

Nail the pieces with a magnetic angle to the base and weld. The distance between them is about 6cm.

Cut out the end cap for the top of the structure and weld it on as well.

Finish each new piece carefully.

Now we make a lever. We take an elongated nut, attach it alternately to both sides of a piece of a profile and encircle it.

Use the angle grinder to cut the hole according to the markings.

Let’s screw the nut on the bolt and, with the help of an angle, we’ll weld it in place.

From the front side of the nut, mount the end cap. Weld the gaps.

Now we have to make the ears. Mark the steel with 4mm thickness and drill the holes.

Brace those ears to the angle grinder over the washers on both sides.

Now weld the lugs to the lever. We tack weld together with an angle grinder, then remove the tool and weld the seams completely.

Attach another pipe for the clamp installation. It will also perform the role of adjusting the slope of the circle.

We make the clamp from a 2mm thick strip of steel. First we bend it by hand, then, using a hammer and vice, we make the necessary shape.

Drill 8 mm holes in the clamps. Strip, put in the bolts, tighten the nuts, tighten the nuts, pull out the bolts and weld.

We drill a hole in the lever, and insert the axle with an 8mm thread. We’ll weld it.

Remove the clamp and the axle and finish the connection. You will adjust the angle of inclination with this axis.

Basic steps

The next step requires pieces of profile pipe with previously drilled holes, bearings, bolts with nuts and washers, and a piece of stud.

The author assembles the rail system from all these parts. The profile pipe is inserted into the obtained device. Then we make adjustments, you need to tighten the nuts to get rid of backlash.

Further it will be required two more pieces of profile pipe and two pieces of building angle. We weld the parts together. Drill fixing holes in the angle bars.

Drill one hole in each of the profile tubes, and then put the elongated nuts in each hole.

Make a base out of plywood. Screw the angle and profile parts to the base, and fix a fixture made from sections of profile pipe 2020 mm.

We mount the fixture on the angle grinder and fix the profile tube to it, which is then inserted into the rail system.

In the last step, we screw to the base the stop bar for the workpieces, made from an angle. The strip itself can be set at 90 and 45 degrees.
