DIY mini miter saw for wood. Circular saw from a conventional grinder

Miter saws are made by many power tool companies. It is used in everyday life and by professionals. Therefore, the device has many varieties, differing in functionality, dimensions, power and price. When choosing a tool, each buyer is guided by his own needs and capabilities. Someone needs trimming for infrequent use. For example, for repairing an apartment or making doors and windows made of wood in the country. Others use a saw every day at work. Based on these requirements, a tool is selected for domestic or professional needs.

Purpose and application of miter saws

To manually cut the material at an angle, and even straight, you need to make a lot of effort and use special tools. To facilitate this process, electric miter saws were invented. They make it possible to cut workpieces exactly at the required angle and inclination. That is, you can change the angle both in the horizontal plane and in the vertical one. The tool has found application among assemblers, carpenters and finishers. Miter saws are used to make furniture, doors, skirting boards, windows, flooring and much more. The tool can cut not only wood, but also plastic and metal corners and pipes.

It is convenient, easy and fast to work with a miter saw.

Instrument device

The main elements of the miter saw:

1. Saw blade with protective cover.
2. Handle with start button.
3. Engine.
4. Longitudinal stop.
5. Stanina.
6. Ruler.

Types of miter saws, what are the differences

All miter saws are divided into two types:

Miter saws are:

• household. The materials from which they are made are not strong enough. Therefore, such devices are not suitable for everyday long-term use;
• professional. They have improved specifications and more functionality... They can work in an enhanced mode every day.

Main selection criteria

Before you go to the store and consult with sellers, read the parameters that you should rely on when buying a tool. And then you will be able to rationally make your choice.

• power. Affects performance and speed of work. With its increase, the weight and cost of the tool grows. Household trimmers consume less energy than professional ones;
• disk size. The depth and speed of the cut depends on it. Also find out if there are removable disks for the selected model of the instrument on the free sale;
• cutting parameters. Angle, width and depth. The saw should cut the workpieces at the angle required for your purposes, preferably in both directions. The manufacturer also indicates the maximum depth of cut when working at an angle of 45 and 90 degrees to the surface. The function of limiting the cutting depth is important. It is used when grooving and processing workpieces by thickness;
• the presence of a horizontal broach. Allows you to increase the kerf width by moving the cutting part in the horizontal plane. In one pass, you can cut a fairly wide workpiece.
• the number of revolutions per minute. Affects the cleanliness of the cut and makes it possible to work with hard materials. The number of revolutions from 4000 and more is a very good indicator.
• engine's type:
  • collector. It is necessary to check the armature regularly, but such an engine has more torque;
  • asynchronous. Runs quieter and longer;
• transmission type:
  • toothed. No slippage under heavy loads;
  • belt. It makes less noise and dampens vibration, but the belt breaks more often than the teeth of the gears wear out;
  • straight. There is no gearbox, fewer rubbing parts, but lower torque;
• swing system design. She must:
  
• security systems. The miter saw must contain components that ensure safe use:

Miter saw Metabo KS 216 M Lasercut 1350 W

I chose between Makita. Metaba has a more comfortable working handle and a laser. True, you need to get used to the laser, but it is tuned exactly. I put a clean disc on aluminum, a saw and pieces of wood.
Satisfied, I recommend.

Miter Saw DeWALT DW713 1600 W

Decent saw for a cost of 12300r, took it at a discount. I chose between the boshes, but settled on this model. It's just that in boshes more often the price rises because of the accessories included in them (a clamp supporting long parts of the bar, a laser sight), I like the weight, it is average, I will not say that it is light, it seems to me that this device is light and should not be, inspires confidence ... Made very soundly, I really liked the adjustment at the angles, easy and without any torsion there, like the competitors. Large work surface. I was chasing the backlit model, and I'll tell you it was worth it! The first day I worked late on the street, I practically did not do this to myself additional lighting since the cutting line was always visible! I recommend XPS.
Just a wonderful native disc with large teeth! Immediately I bought myself a Bosch disc, for a clean cut of laminate rolled up in plastic, and so he lost to a clean one! (I had to use it only for cutting aluminum, which he did just fine).

Miter saw Makita LS1018L power 1430 W

It smells very much of cheap Chinese, but I bought it at Makita-online with discounts for 26 tr (sanctions, damn it). Visually - low quality of manufacturing of the aluminum body of the broaching mechanism (cast, processed with a LARGE file and painted, the paint does not hold well, peels off on a new tool). The turntable is flat, milled, but where it is painted, the story is the same. Not exposed to 0 and angles, as well as the laser (I had to myself, lost 15 minutes). Corner setting scales are PRINTED AND ADAPTED as on the Riobe. some of the sticker is removed from the new, out of the box. Not compact - it takes up more than a meter (1080mm) in transportable condition.

Miter saw ZUBR ZPT-255-1800 PLR with a power of 1800 W

This is my first experience with such a tool.
I set the corners in 5 minutes with the help of a regular square (on the forums they scare that I have to file the guides in inexpensive models equalize). And then work began.
I am quite satisfied with the purchase. If not for the laser, there would be 5 ...

Tool setup and adjustment

Absolutely any saw needs preliminary adjustment, regardless of the company and model. This is like the first Maintenance... The main thing that is required from the saw is the accuracy of the tilt and turn angle. Any saw can be modified, improved and increased its class. Remove all additions and extensions, such as clamps, from the tool. You will need a scalpel or small knife with a rigid blade. Casting is accompanied by the formation of flash, which must be cut off if it interferes with maintenance.

Side stop

1. Raise the saw unit. Remove the side stand.
2. In some saws, it does not have right angle with a bed. The stop touches the base at two points. The bases of these points must be vertical to the surface. If there is no right angle due to uneven paint coat or burr, sand base surfaces... Cut off any flakes first, if any.
3. Sand with a disc machine or sandpaper. Place it on a table and rub the stop in longitudinal movements.
4. Make a small chamfer where it meets the base. So that the chips that inevitably arise during sawing are hidden here. This is to ensure that the chips do not interfere with the formation of the desired cut angle.
5. Place the stop in place. The fixing holes of the stop are oblong for adjustment. When installed, it can be moved back and forth and rotated.

Rotation fixation unit

Miter saws have two types of dials. One ruler has a removable element. On the other, it is not dismantled, and the limb itself has slots for frequently used angles.

The fixing rod has a tapered sharpening and does not fully fit into the slots of the dial.

How to fix an arbitrary angle

There are situations when you need to set an angle that differs by 1–2 degrees from the fixed value. When setting such an angle, a breakdown occurs and a value is fixed, which we do not need. To prevent this from happening, you need to turn the locking knob while pressing the key.

Setting an angle of 90 degrees in the horizontal plane

Most often, users apply a square to the disc and base. This is the wrong way for three reasons:

• during the installation of the equipment, debris could get in and the equipment was installed unevenly;
• the disc itself turned out to be deformed;
• when we apply the angle to the rig, a light load is enough to wobble the disc a little.

Prepare a piece of plywood, a thin strip, a 10mm strip and double-sided tape.

Setting other angles

Possible malfunctions and repairs

Let's consider common faults.

Divergence of surfaces in the side stop

The surfaces of the side stop converge at some angle or are located in different planes. This greatly affects the sawing accuracy. When filing to the right or to the left, different results are obtained.

Cutting accuracy is impaired

It is necessary to identify the curved element: disc or flange. This operation must not be performed by starting the engine from the mains. Firstly, you run the risk of serious injury, and secondly, when the engine is running, this method does not work.

1. Switch off the saw. Raise the protective cover.
2. Take a marker and place it on the side of the disc. Keep the marker straight. Rotate the disc until full turn.
3. Lock the spindle and loosen the disc. Rotate 180 degrees. Tighten it.
4. Take a marker of a different color and repeat drawing the circle next to the previous one.
5. See where the half rings are located. If they are on the same part of the disc, then it is crooked. Replace the disc with a new one. If the half rings are on opposite sides, then the problem is with the flange.
6. Remove the disc and flange. The flange is a support washer that is attached to the shaft along with the disc. The reference and landing planes must be parallel. The reference area is formed by turning.
7. With the disc and flange removed, the saw is completely safe. Run it from the network.
8. Take a simple pencil and touch the surface to feel if there is any beating. Metal object Do not do this as this will compromise the accuracy of the surface finish. If there is a runout, then you need to change the shaft.
9. If there is no beating, then put the flange and screw it on with the screw. Take your pencil again, start the saw, and touch the flange. If runout is present, the flange must be machined.
10. To do this, take a block and a nail file. Secure the block with a clamp inside the casing. He will be the support. Start the engine and stick the saw blade into the block slightly further from the flange. Move the file gradually towards the flange. This must be done carefully so that the nail file removes a small amount of metal. Drive the file not with a plane, but with a curved part and start from the center to the periphery. This task is long and tedious, but it works 100%.

Engine and gearbox repair

The following factors indicate the presence of breakdowns in the engine or gearbox:

• the disk does not spin, but the engine is running;
• the smell of burning;
• sparking in the area of ​​the engine;
• the saw is not picking up power;
• the instrument is unstable.

If at least one of these signs is present, proceed with the analysis.

How to make a DIY electric miter saw

The miter saw can be made different ways... Consider options with a grinder and a manual circular.

From the grinder

1. Remove the disc and additional handle from the grinder. Cut a sheet of wood or metal for the bed. Metal is more suitable for the grinder. Weld a 30 * 30 mm pipe on both sides. Make an extension for the bed the same width. Weld a 25 * 25 mm pipe to it and insert into the first pipe.
2. Take your legs for washing machine... Screw two nuts to them. One small, the other elongated. So that the height of the legs is adjustable. Weld the legs on the corners of the bed.
3. Make metal fasteners on the grinder gearbox housing.
4. Collect swivel knot from bicycle scrap metal.
5. Weld it with one end to the bed and the other to the grinder.
6. Place the spring on the pivot assembly that tightens the pads. And a stopper so that the grinder does not fall back.

   Saw workbench: drawing marking, trimming installation

   1. Make a stable table out of a metal frame with a 40-50 mm thick table top.
   2. At the edge or in the middle, measure the area that the saw will occupy. Set up a platform in free space, as high as the base of the saw.
   3. In the area under the saw, make fasteners
   4. Place the trimmer on the table and screw it on. Draw a line on the platform to continue with the side fence of the saw.
   5. Install and screw the square profile along this line.
   6. Install a ruler on the profile.

   Buy a miter saw according to your needs. Do not neglect its setting. This process is very precise and subtle. Approach him responsibly. Then you get a workable and durable tool.

A miter saw is most often a circular saw, the structural features of which allow you to cut many materials, including metals, with the best effect at one angle or another.

Today we will tell you what is Miter saw, what are its characteristics, how you can assemble it yourself and what to consider when choosing finished models... It is worth thinking about assembling the trimming with your own hands, because this will save you a lot of money.

Key features of miter saws

On sale, as a rule, there are two types of saws:

• narrow-profile, with a specific purpose;
• models equipped with a number of auxiliary functions.

Different types of saws differ from each other in terms of cost, which depends on the functions of the model and its manufacturer. Most famous brands drank is:

• Bosch;
• Metabo;
• "Makita";
• Interskol and others.

This type of saw, as a miter saw, includes the following elements:

• saw blade for cuts;
• engine;
• footboard with engine start button;
• handle for holding and guiding the instrument.

Regardless of the type, the trimmer is equipped with a disc based durable material, which makes this tool universal for certain household needs.

Miter saw motor may be:

• collector;
• asynchronous.

The motor of the first type does not need constant monitoring and lubrication of parts, and the second type, asynchronous, is distinguished by its durability and quiet operation. Most often it is located to the right of the cutting element of the structure. However, there are models of tools where the engine is placed at the back, this significantly improves visibility during manual work.

The engine starts to work by means of a gearbox, and its transmission can be gear or belt. If it is a belt, then the tool makes less noise and there is no vibration of the cutting element. A gear prevents the saw from slipping when cutting under heavy loads.

Features of the use of miter saws

Trimming, even assembled by hand, is capable of sawing such types of materials as:

• plastic;
• wood;
• aluminum;
• alloys based on non-ferrous metals.

The great thing about these kinds of tools is that they are compact and don't weigh too much. Maximum weight of the trimming machine is 30 kg, this indicator depends on the model and its functional features.

Miter cuts are widely used in the field of woodworking, where they can be used to perform a large number of tasks.

Saws of this type allow you to make "mustache" connections, and such machines are very popular in baguette shops and in the manufacture of furniture.

Some cutting-off models of tools are equipped with replaceable discs, which are designed to cut a particular material. Basically, all types of miter saws are designed so that they can be positioned at a certain angle and size when turning the work table. And some models allow you to make a turn only in one direction, this cheapest options... Naturally, the cost of trimming modifications, which can rotate in different directions, will be much higher.

If the tool can be rotated 360 degrees, even very complex workpieces can be machined with it. Its saw head is tilted in relation to the table and can be easily adjusted to rotate. But remember that in order to determine the angle of rotation, you need to decide on the materials and workpieces for work.

The most optimal rotation of the tool through an angle is about 50 degrees.

How to make a miter saw with your own hands

If it is financially difficult for you to acquire an instrument, then you can assemble it yourself. How to do that, we will tell you below.

To make the bed, you will need:

• thick sheet of metal;
• steel corners (you can take an old bed).

Welding machine in steel sheet cut a hole, and its edges are processed with a file.

An electric motor for assembling a tool with your own hands is not needed too powerful, 900 watts will be enough. It is installed on the base by means of an additional spring, which acts as a stabilizer.

To tilt the tool, efforts must be made, in particular to move the handle. But the result is a smooth motion for the saw unit.

Instrument parameters will be like this:

• 100 mm - radius of the cutting disc;
• 1500 rpm is the spindle speed.

All these parameters will allow you to easily process wood up to 70 mm thick using a self-assembled tool.

Be sure to include adjustable uprights and supports. Take a channel as the base of the pendulum riser, which will rest on a metal base.

As a result, our tool will be more durable and weighty, but cross-cut work with it will be done easily.

You can take a three-phase electric motor with a power of 2200 W, and for support, a swinging plate on hinged joints. Due to the folding device, the belt of the pulley of the electric motor is tensioned. The pendulum can be made based on the material that has been prepared for the frame.

For comfortable work with wood, the saw diameter should be 420 mm, and the number spindle revolutions per minute - from 2800... As you can see, you can not only buy high-quality trimming, but also assemble it yourself.

Benefits of homemade miter saws

Homemade trimming tools have a number of such advantages:

Disadvantages of homemade tools

Of course, along with the advantages of the models homemade assembly, there is a number of disadvantages hand-assembled saws compared to factory counterparts:

• not all design details have good quality, therefore, there is no guarantee that the tool will last for a particular time. Manufacturers always provide the buyer with information about warranty period product service, which, most often, is about three years;
• poor performance compared to factory counterparts. Of course, it is extremely difficult to assemble a tool on the basis of improvised materials with your own hands. High Quality and high power. Components must be selected as accurately as possible;
• not every master is well versed in information on electric motors and other mechanical devices. If the choice is made incorrectly, then the tool will have to be repaired often, and this can result in financial investments exceeding the cost of a factory saw;
• even if the factory model has the same technical characteristics with the self-made one, it will be more functional. For example, if only rectangular cuts can be made using homemade products, then using a factory saw you can process boards at an angle of 45 degrees;
• safety of use. Rarely homemade model the trimmer is equipped with protective covers, sometimes the parts have a number of minor defects that can cause injury when working with the tool. Factory tools are safer to use.

End plate selection rules

Of course, if you have experience and you are not ready to invest a lot of money in buying a tool, you can do it yourself. And if you decide to purchase a model from the manufacturer, then when buying, be sure to consider the following so as not to be disappointed later.

For lovers of tinkering, the miter saw is one of the most popular and must-have tools. Replacing the primitive miter box, it quickly gained popularity in small workshops and in large-scale production.
The advantage of this tool is the precise and safe cut under a straight or given angles... The engine is most often located above the bed, and is mounted on a movable carriage with a handle. The depth of cut is set by the stops at the base, and by hand. Power tools of this kind have already been appreciated by many professional craftsmen and novice amateurs. We offer you to do this too!

The advantage of homemade trimming

Today, a miter saw is no surprise. A lot of modifications, from branded to cheap Chinese ones, with longitudinal and angular cuts are present on the market. However, their cost sometimes goes off scale, and the accuracy does not always correspond to the declared one. Is it possible to do without buying a specialized tool, you ask.
The installation we offer proves that the rip saw can also be made at home. Its assembly costs are minimal. In addition, the drill on the basis of which our crosscutting is made can also be used for its intended purpose.

Required materials and tools

Expendable materials:

• For the bed: a sheet of plywood with a thickness of 14-20 mm, sheathed with galvanized on one plane;
• Cutting disc with victorious soldering for longitudinal cutting, diameter - 125 mm;
• Three pieces of plywood: 30x15 cm - for the handle, 24x15 cm - for the carriage, 18x14 - for the base stand;
• One-piece window hinge -1 pc;
• Drill (without reverse);
• Two pairs of U-shaped split rails for furniture boxes;
• Hardware: bolts, nuts, screws;
• Cardboard for the template;
• Joiner's glue, wood varnish.

Instruments:

• Drill or screwdriver;
• Electric jigsaw with a saw for wood;
• Pliers, drills, attachments for tightening self-tapping screws;
• Painter's knife, tape measure, pencil, varnish and glue brush.

Getting Started

1. We fix the base stand

We mark the position of the base stand on the bed, shifting it to the left from the middle, and cut galvanized under it with a chisel.

We take a piece of plywood 18x14, and screw it vertically onto 3 self-tapping screws, having previously glued the connection to the bed.

For more stability, you can put down several stops in the form of corners from the same plywood. We put them on glue on both sides of our rack.

2. We make the handle

According to the template prepared in advance, we mark the handle of our trimming. We use a piece of plywood 30x15cm.

It is convenient to cut curved lines with a jigsaw. The closed loop must first be drilled with a 8-9mm drill to fit the width of the jigsaw.

After cutting, we process the edge of the plywood with a rasp or sandpaper, and make the handle streamlined and free of burrs.

3. We connect the handle with the carriage

For this we need furniture guides.

We fix one of their parts on the sides of the handle, the second on the carriage.

Both pairs of guides must match so that the bed and the arm are practically in the same plane, and provide free movement of the arm without any jamming.

4. Fixing the drill

From the back of the carriage, we attach the drill holder to the self-tapping screws. It can be made from a small piece of plywood by making a sufficient hole for the chuck.

We press the drill with a cuff made of a galvanized plate, pulling it onto the screws to the handle.

5. Install the carriage

For a more convenient arrangement of workpieces on the bed and their facing, it is necessary that our carriage has a vertical stroke. This condition will provide us with a window hinge.

We fasten it with self-tapping screws to the edge of the carriage and to the base so that the movable part can rise and fall to the right angle position. In this case, the carriage will act as a stopper and will not allow the cutting disc to drop below a predetermined level.

6. The final stage of work - we put a cutting disc, a protective cover and a limit bar

Using an M8 bolt, 50-60mm long, we make a shaft for our trimming. For a disc, it is best to choose a wider washer, because the bore hole at cutting discs this diameter can be 15-20mm.
We tighten the disk on our shaft with a locknut, and clamp it in the drill chuck with a wrench.

We place the protective cover over the cutting disc, and also attach it to the self-tapping screws. It should be made from a plate over 1mm thick.

We make a trial run of our miter saw and check its longitudinal stroke. The cutting disc should be literally a few millimeters deep into the bed.

Basically a miter saw is the most common circular saw mounted above a table. Due to some features of the tool, it becomes possible to cut with great effect different materials at a specific angle.

This homemade miter saw can cut:

• wood;
• plastic;
• aluminum;
• various non-ferrous alloys.

The most important characteristic features miter saws are:

• compactness;
• light weight.

The weight of the machine can fluctuate and reach a maximum of 30 kg. It all depends on the specific model, its functional capabilities. Miter saws are widely used in the woodworking industry. With their help, you can solve a variety of tasks.

The use of a miter saw allows you to make a "mustache" connection. Such machines are called "trimming and trimming". This tool is widely used by the masters of baguette workshops, it is also used in the production of furniture.

Miter saws allow you to cut parts made from a wide variety of materials. Cut-off models use replaceable discs that allow you to cut the right kind of material. Almost all types of miter saws are made in such a way that it was possible to set the tool at a specific angle and a specific size by rotating the table.

On some saw models, it is possible to rotate the tool only in a certain direction. Usually the cost of such a saw is quite low. When the saw can be rotated in different directions, the machine has many added benefits. However, the cost of such a device is very high.

The saw can be rotated 360 ° to machine workpieces of any complex shape. The saw head is tilted relative to the work table. It is quite easy to adjust the saw blade rotation.

Every master who has conceived to carry out homemade trimming should take this into account the most important moment... To determine the required angle of rotation, he must determine what materials and workpieces will be processed by the miter saw.

Rotation of the saw through an angle in the range of 45-55 ° is considered normalized.

Making and assembling a do-it-yourself miter saw

To make the bed, you need a thick a metal sheet and steel corners. An old bed is perfect for this purpose.

With help welding machine a hole is made in the steel sheet, the edges are finished with a file.

A low-power electric motor is suitable for work. 900 watts is enough. It is mounted on a base using an additional spring. It plays the role of a stabilizer.

Such a design requires some effort to tilt the system. To move the handle, you have to apply significant forces. The result is a smooth movement of the saw unit.

Device parameters:

• cutting disc radius - 100 mm;
• spindle speed - 1500 rpm.

These characteristics make it easy to handle wood with a maximum thickness of 70 mm.

If there is no bed at hand, the bed can be welded from metal corners.

Adjustable feet and legs should be provided. The basis of the pendulum rack is a channel supported on a metal base.

As a result, the installation gets additional strength, its mass is added. On such a machine, it is very easy to perform homemade trimming.

For work, you can use a three-phase electric motor with a power of 2,200 W. As a support, a swinging plate is mounted, which is held by the hinge joints. The pulley belt of the electric motor is tensioned by a folding device. The pendulum is made from the material that was used for the frame.

Saws with a diameter of 420 mm are suitable for work. The number of spindle revolutions must be at least 2800 rpm. With these parameters, you can process wooden blocks 70 mm wide.

Miter saw advantages

First of all, this applies to small financial investments. The cost of all components is quite affordable for every craftsman. Thanks to the high savings, an original and multifunctional trimming machine... However, such high savings can only come about if each component can be purchased very quickly.

For example, the absence of an electric motor of a certain power can affect the efficiency of the entire structure.

The advantages of such a homemade miter saw can be attributed to the fact that it fully meets the needs of the manufacturer. He can select the desired parameter of the machine, make a table suitable size, set the saw rotation speed.

Of course, the advantage of such a machine is the master's knowledge of all the details and assemblies of the trimming device. He can very quickly fix the breakdown, spend necessary repairs... Such a homemade trimming can be considered a real competitor to factory counterparts.

The presence of a cross-cut saw in the arsenal of a summer resident greatly simplifies life. This type of saw can be found in any building supermarket, but the price of a branded crosscut saw will cause huge damage to the family budget.

In order not to overpay, you can assemble a miter saw with a broach from improvised material and old tools available to almost every self-respecting man. In this article, we will walk you through the process of assembling a homemade miter saw and find out exactly what tools you may need to do this.

Characteristics of a homemade miter saw:
✓ 350 mm cut length;
✓ 4.5 thousand rpm;
✓ relatively low weight.

The advantages of a homemade miter saw

Since the design is based on an ordinary grinder, it can be removed and used in work with other material. Homemade machine, unlike its factory counterpart, is completely universal, largely due to its low weight and the possibility of complete disassembly. Another advantage of such a saw is the relatively inexpensive assembly cost: no more than 500 rubles (not including the cost of a used grinder) are spent on everything.

Disadvantages of a homemade miter saw

Difficulties in selecting the accuracy of cuts
For the best possible result, you will have to make several rough passes, then fix the thrust and make a fine saw.

Noise
Due to the fact that the saw is based on a noisy grinder, the unit will give out a lot of noise. This deficiency can be corrected with the help of a more modern apparatus.

The nuances of assembling the construction of a homemade miter saw

The upper pivoting part of the unit is mounted on a king pin with the largest bearing on the market. To 150 mm bearing with outside lugs are attached through which the unit is attached to the working surface using standard M6 screws. The clip is protected from debris by a specially made partition.

As a broach, it is recommended to use shock absorbers from the front struts of a passenger car, which are used in many cars, for example, in the VAZ 2108-15, and shock absorbers from a truck will make the structure too massive and unmanageable. You can buy them at almost every scrap metal collection point. Before installation, disassemble the shock absorbers, drain the oil, make "air" holes and cover them with residual cloth.

For more comfortable work with the saw, the soft start system should be adapted to the grinder, because without it the starting jerk will be too strong. Moreover, the installation of the block contributes to the reduction and regulation of the number of revolutions. To increase safety, additional protection is attached to the grinder and the bed.
