Homemade metal cutting saw

Wouter writes – “Home made metal cutting saw. No welding required. My wife’s grandfather made lots of his own tools, this is another nice one. This metal cutting saw uses an abrasive disk spinning at about 5000rpm. Because of the big pulley on the motor it’s all pretty quiet. This machine offers no protection to the operator. Do not copy the design without adding a belt guard, blade guard and other safety measures. “ – Link.
