Here our student is using a circle jig. She has to cut 6 circles at 18″ each. We’ve clamped a piece of wood to the saw’s table. Then, a nail in the center of the circle to be will guide the wood as Samantha turns the square. The most important thing to remember is that the nail must be in line with the blade. If it isn’t, the wood will try to guide the wood in the wrong direction.
Here we have the entire machine. The two wheels hold, support and guide the blade. The blade runs clockwise. The bottom wheel is the “drive” wheel: it has the motor attached. The top wheel simply spins. Notice that the doors are open. Never run the saw with the doors open. Always have the doors closed.
