Radial Arm Saw Guide – Uses, Advantages

One may think that radial arms became outdated because of the development of new tools into the place. And people think that they are old technology when we compare them with the miter saw or other circular basic saws. But, it is not like that. Here, we will show all the aspects of the radial arm saws. You can find here how to use them, what are the advantages and what you can do with them. Because they are very useful tools lots of woodworking workshops are using this technology in general.

What is Radial Arm Saw?

Radial arm saw.

The radial arm saw is an old technology that is developed by DeWalt to make different kinds of cutting operations with the same machine. There is a circular saw that is connected to a horizontal structure. Along this horizontal structure, the blade can make a reciprocating motion. And this vertical structure or arm is connected to the vertical arm which gives the advantage to rotate along an axis. And also the circular saw can rotate along the horizontal arm. This is the general construction of the radial arm saws in general.

As yous see above, you can guess its versatility. Because different kinds of cutting jobs can take place with radial arm saws in general.

To understand the general working principles of the radial arms more generically and technically, it is very important to take a look at the general parts that these machines constitute. So, you will understand that the working principle is very basic.

Radial Arm

Radial arm saws take their name from these machines in general. This is the structural part that holds the circular saw on itself. You are the direction of the circular saw that is attached to this according to the workpiece And the radial arm is attached to the vertical structural member that allows the rotation of the circular saw along its axis.

Electric Motor

The electric motor is directly attached to a circular saw. Once you open the electric motor, the radial arm will start to rotate. While you redirect the circular arm, the electric motor is direct with it.

Carriages

The radial arm has rails which are called carriages in general. The circular saw can move along this carriage in general. So, it is very easy to move the circular saw along the carriage to adjust the place of cutting on the workpiece.

Once you adjusted the placement of the cutting tool over the carriage, you can easily lock the cutter with the carriage lock knob. This will provide structural stability in the cutting operation.

Blade Guards

Some machines do not have these guards. But they are very important in terms of occupational health and safety. The blade guards are very important guards that save the workers and operators from any possible accidents.

Fence

On the cutting table, the use of fences is very common to direct the workpieces to feed the cutting operation. For some of them, you can adjust the orientation of the fence in general. So, it will be very easy to orientate the fence in the possible direction.

Feather Board

This is another structural part that supports the feeding motion of the workpiece to the cutting tool. So, you will easily direct the tool with the help of the feather boards. And by using these structural members, you generally save yourself from any kind of injury.

Workpiece

The workpiece is the part that you are trying to cut with these tools. It is very important to fix the workpiece along the feed direction. The only job of the operator is to supply the workpiece along the feed direction. If the operator does multiple things such as both directing the cutting tool and giving the workpiece, it can cause very bad accidents.

Clamps

For fixing the workpieces, the use of clamps is very important. Clamps are the devices that fix the workpiece along the cutting direction. So, it will be very easy for you to adjust the clamps.

Elevating Handwheel

Handwheels are very important to elevate the circular saw over the vertical position. After the elevating of the saw takes place, you can easily fix all the systems in a specific elevation.

These are the most general and important parts to operate the radial arm saws in general.

Advantages of Radial Arm Saws

Like the other cutting tools, there are different kinds of advantages of radial arm saws in general.

  • As you see below, you can make different and versatile cutting operations on different kinds of materials. Having only one radial arm saw, you can easily apply a very good cutting operation. So, it will be very easy for you to apply the different kinds of cutting operations.
  • In general, cutting depths of they are better. If we compare with the miter saws, the diameters of the circular blades are much wider. Soı you can obtain much more deep-cutting operations with them in general.
  • One may think that the radial arms saws are not compact and take up lots of space in the workshop. But if we consider their versatility of them, we can easily find out that they are better at space saving. Because you do not need to use different kinds of machines to obtain different kinds of cutting operations.

Disadvantages of the Radial Arm Saws

It is also very important to consider the disadvantages of radial arms saws in general. So, it will be very easy for us to determine if we need to buy a radial arm saw for our workshops.

  • Safety is one of the major problems with them. Because the blade can freely move along the different axes and different orientations. And while operations are making complex and compound cuts, they are more prone to be dangerous if we compare them with the other basic machines.
  • Precision is another problem with them. The precision of these systems is lower than the other basic machines. The versatility provides a lower precision if we compare it with the other saw operations.
  • You can obtain different kinds of cuts with the radial arm saws. But the accuracy is not good as the other kinds of machines.

What Can You Do with Radial Arm Saw?

Woodworking is the most common application that the radial arm saws are generally used. In most of the big woodworking workshops, you can find radial arm saws are used.

In woodworking, some cutting operations are very important. By making these cutting operations, you can easily obtain different kinds of shapes and cuts in general.

Rip Cuts

Rip cuts are the most common cutting type in woodworking in general. They are the cutting operations that cut the wooden parts in the longitudinal axis. So, the cutting operation takes place on a very long axis. The machine that you are using must have the ability to feed the workpiece on the table.

The rotating saw of the radial arm saws provides an excellent feed place for the workpieces to make the rip cuts over them. They are very good machines that you can make rip cuts on wooden parts.

Cross Cuts

Cross cuts are also a very common cutting type in woodworking. Here, we are cutting the wooden part from the short axis. They are generally very basic cutting operations to divide the long and big wooden parts into pieces.

You can easily make cross-cuts with the radial arm saws without any problem. It will be very easy for you to cut the different kinds of wooden parts in general.

Miter Cuts

Miter cuts are also like cross cuts. But you are making the cutting operation at a specific angle. So, there are two ways to do it. You need to rotate the workpiece, or you need to rotate the cutting machine. In radial arm saws, rotating the machine is much easier. You just need to rotate the circular saw with your hand to the angle value that you want to obtain for the miter cuts in general.

Bevel Cuts

Bevel cuts are also very important and hard-cutting operations in woodworking applications. The difference between the bevel cuts from the miter cuts, you are giving an angle to the cutting direction. In mite cuts, you are giving this angle to the cutting orientation.

This cutting operation is generally very hard to apply with conventional tools. But with the radial arm saws, you can easily adjust the orientation of the blade to obtain the bevel cuts easily. The versatility and the ability of the radial arms saws take place with this cutting operation.

Compound Cuts

Think about that you need to make a compound cutting operation that includes the bevel cuts and miter cuts at the same time. For example, you can not do this kind of cut with normal circular saws. But you can easily apply this cutting operation with the radial arm saws.

Dadoes
