The miter tool is lightweight, compact. Effective as a stationary machine. Fixed fixation of the workpiece allows you to perform high-quality cuts. Some trimming samples include devices for optimizing angular cuts, a speed regulator that allows you to select a mode depending on the type of material, the required quality of processing. The trimming unit can be made independently.
Most often, the saw is assembled from a grinder.
For a good job:
- The original disk tool must be at least 4,500 rpm.
- Cut length - not less than 350 mm.
If necessary, the grinder mounted on the table for the miter saw can be dismantled, used for its intended purpose.
Assembly process
First, make a table on which the cutting unit will be installed. The frame is constructed from a metal corner by the welding method. The top is covered with a thick sheet of metal with a longitudinal hole. The edges of the bed are filed.
The saw from the grinder is mounted on an axis. This allows you to cut the workpiece at an angle. The rotary mechanism is fixed by installing it on a bearing with a diameter of 150 mm. The structure is fixed by a mechanism connected to the axis. The axis is lubricated from time to time to exclude the occurrence of squeaking, excessive friction.
For cutting the workpieces at a certain angle at the time of assembly, the saw is equipped with ears welded on the outside of the machine at a small distance from each other. If this is not done, there will be backlash, the accuracy of the cut will suffer.
When working, it is necessary to ensure that sawdust does not get into the bearing: this can lead to rapid wear of the mechanism, and rotation of the disk will be difficult. For extra protection, use grease.
The most effective for processing wood trimming with a broach, shock absorber. It is better to choose samples mounted on trucks: they are more resistant to aggressive mechanical stress, hardy. The part is freed from oil, equipped with technological holes that will serve as ventilation ducts. As a protection against sawdust and wood dust, the holes are tightened with a mesh with a small section of cells.
Another useful option for the face circular saw is the soft start module. Thanks to him, when starting up, the machine does not make sharp jerks. The principle of operation of the part is to reduce the speed at the start. As a result, the cutting disc trimming is gaining momentum gradually. It is difficult to assemble the stabilization module independently. It is recommended to remove the part from another device or buy it.
At the final stage, a guard is made to protect the miter saw from falling into the working area of the torch of external objects.
If there is a conventional circular saw, you can make a movable carriage. It is easy to install, assembled from plywood sheet, guide rails and fasteners: bolts, screws.
Important points
The machine makes a lot of noise during operation.
In order for the tool to accurately perform the intended cut when processing the ends of the workpiece, you must try to position the grinder as accurately as possible relative to the wooden parts. The placement of the cutting element can be adjusted using the bars, while the thrust must be fixed with a bolt.
Trimming machine can be installed in the garage, workshop, basement, other places. The main thing is that the working structure is firmly connected to the base.
Carefully select the saw blade. It must comply with the specifics of the work, the characteristics of the material.
