Circular manufacturing process
A 12.5x21 cm blank is cut out of MDF for the sole of the circular. Marks are placed along its long side 7 and 17.5 cm from the edge. Between them, the workpiece is ground 5 mm deep.
A 5x5 cm square is cut out of MDF. It needs to be drilled in the center for the motor shaft with a coupling, and on the side for the motor mount.
The workpiece is glued to the sole, and the engine is screwed to it.
A coupling is placed on its shaft.
Next, a casing for the saw blade is made. To do this, cut off a regular PVC pipe plug.
A hole with a diameter of 50 mm is sawn through it, then it is glued onto the sole.
To make a handle for a circular saw, you need to glue 4 pieces of MDF and cut it out of them.
It is screwed to the sole with self-tapping screws.
There is a push button embedded in the handle.
Next, the wires are soldered through it to the engine.
They are connected to a power supply or battery. A disk is installed on the coupling.
Now, when you press the button, the circular saw will cut.
Using the same technology, you can make a mini table saw - https://enn.washerhouse.com/6098-izgotovlenie-nastolnoj-mini-pily-12-v.html
