I bought this miter saw from Japan recycle shop. It is 100V power tool from Japan. I want to use this miter saw in my farm for irrigation installation. It is easy to use this tool with battery instead of electric source. I decided to convert this tool from cord to cordless by replacing the motor structure from AC to DC power by 18V battery. You can see the process detail in the video.
