THE SCROLL SAW
The Scroll Saw is a machine which is used to freehand cut thin wood or plywood into curved shapes. The cutting action is reciprocation. This means that the blade moves up and down rapidly, much as a human hand would move when using a coping saw, but much faster. The blade is a short, narrow one, which can make tight turns and when fitted with the narrowest of blades, intricate shapes can be cut. This saw has an advantage over other saws because the blade can be removed from the saw, passed through a hole drilled in some wood and then used to remove a piece of wood without having to cut an entry path.
The Scroll Saw can be used to cut wood, plastic, cork, foam material and fiberglass but it is not suitable for cutting metals such as steel and aluminium.
The table can be tilted to enable an angled cut, and usually a light is fitted to enable a clearer view of the work. Sometimes the saw has a small bellows fitted, which blows a stream of air over the work area to enable the operator to clearly see the line of cut.

MAIN PARTS OF THE SCROLL SAW
SAFETY PROCEDURES
AT ALL TIMES – IF IN DOUBT, SEE YOUR INSTRUCTOR
- Wear safety glasses or goggles, or a face shield (with safety glasses or goggles).
- Keep fingers clear of the blade path.
- Use both hands and keep fingers at least 4 in. from the blade at all times.
- Do not set the speed too fast. When in doubt, slow the speed of the machine.
- Never pull or force a jammed piece through the equipment. Shut the power off and then carefully dislodge the piece
- If the blade breaks, turn the power off immediately and step back. Inform the teacher that a new blade needs to be put on the saw. Ask the teacher for help if necessary.
- Make all adjustments with the power off.
- When using the saw do not force the piece by pushing too hard. Trying to cut too fast only results in a poor cut that is often far from your pencil line.
- Plan your cuts carefully. Saw curves gradually. Sudden twists will cause the blade to bind or break. Use relief cuts if necessary.
- Always make short cuts first.
- Remove scrap pieces from the table only after the blade has stopped.
