Probably everyone who makes repairs on their own has come across the fact that you need to cut a board or pipe, cut the plinth. In practice, this turns out to be quite simple.
The most convenient tool for this is a circular saw. In this article, we'll show you how to learn to cut at a forty-five degree angle with a circular saw - tips for beginners.
The circular saw is more efficient than some other electric tools.
Saws of several types are produced, differing in the field of application and characteristics. The main application of a circular saw is still sawing boards.
Let's get acquainted with some types of circular saws:
There is a 120V AC voltage model, as well as a battery that works with different DC voltages;
Available with a set of blades that can be used to cut composite material, concrete, metal, etc.;
These tools are heavier and larger in size. They are mainly used on an industrial scale;
So, for example, most models can be adjusted from 90 to 45 degrees, which makes it possible to cut beveled ends, hipped rafters and cut at an angle of forty-five degrees.
Nearly all saws have a screw with a lever to loosen the bolt that holds the blade at the correct angle for cutting. Some models have a scale that shows the angle of inclination of the blade from 0 to 45 degrees.
Note: The cutting depth of circular saws is from 30 to 130 mm.
You need to know what thickness of boards you have to work with. The choice of saw blade is also very important.
For a neat cut, a disc with a larger number of teeth is suitable.If the blade has sparse teeth, the cut will be faster, but the cut will be rougher.
Cuts with such a saw, as a rule, are smooth and there are practically no chips
This angle is found in the manufacture of various products. Let's start cutting off. First, the foot of the saw is shifted ninety degrees.
Depending on the model, there is a bolt with a red handle on the side of the sole that must be loosened.
Then the sole is displaced by an angle of forty-five degrees and fix the bolt back. We take a piece of chipboard as a blank. We fix it with clamps on the table top so that the part that we will cut off goes beyond the table.
Then the ruler is set.
It is usually included with a circular saw. The saw has 2 marks zero and 45. We will cut off 30 millimeters by aligning the three on the ruler with the mark forty-five on the sole. Then you need to tighten the bolt that fixes the ruler.
Next, the sole must be positioned so that the ruler rested against the edge of the workpiece.
The saw starts and after it is fully unwound, tightly pressing the ruler to the edge of the workpiece, they move forward.
If the edges are torn with chips when cutting, do the following:
- Take a small sheet of 6mm hardboard.
- We glue this sheet to the base with adhesive tape.
- With the included saw, immerse the disk in hardboard to obtain a cut with zero clearance.
How to cut smoothly? A certain device is made with a small allowance, after pressing the circular to the stop, we saw off the edge of the base to the desired length.
Along the sawn edge, the line for cutting with a circular saw is determined.
A mark is placed on the board at the sawn-off point. By pressing the lower stop of the device to the board, the edge is leveled. Because the saw first goes through the attachment, the cutting of the boards is more accurate.
In order to make a guide, take a piece of plywood from twenty five to thirty centimeters wide.
It must be secured along the intended cutting line.
When cutting long materials, it takes a lot of time to measure and set the straight guide to the marking line. To simplify this process, it is possible to make a template with your own hands, for example, from fiberboard. The edge of the template is aligned with the mark on the workpiece, and a straight guide is attached to the back side, which must be fixed with a clamp.
A similar template can be used even for jigsaw or router operations.
