What are these two devices in the picture called:

• Scrap Wood Pieces

• Push Sticks

• Safety Sticks

• Stopping Blocks

Place the following in the correct order, when using the Band Saw!

• Keep the wood against the fence and slowly push it into the blade to make the cut.

• Adjust the fence, so it's the proper distance from the blade. This should be set to how wide you want your piece to be cut.

• Turn the band saw on!

• Use a push stick to push the wood piece the rest of the way through safely.

• Stand in front of the Band Saw and have a partner standing on the other side, ready to catch the piece(s) you cut.

What is the purpose of a "Push Stick"?

• To keep your hands/fingers far away from a moving blade, but still allow you to push wood into the machine and cut.

• To slow the blade down.

• To sharpen the blade, so it cuts through the wood easily!

• To align the blade for precision cuts.

Before using the Scroll Saw, you need to check the blade by (a)   and you must adjust the hold down so it's​ (b)   the top of the wood piece.
