The engine of a blender is powerful enough to run a 500W table saw. It can generate speed that is fast enough for the disc to cut wood.
Even if it’s homemade, the output in this video is not your ordinary kind of mini table saw. It comes complete with heat dissipation system, appendage seals to eliminate vibration, fan, bearings, table guide and a saw dust bin. In fact, almost every part of the blender was put to good use. The ready driver and the fan were both installed on the table saw, including the push buttons and the wirings.
