The thinness of the blade allows it to be turned in the work piece at an almost 90 degree angle, which allows the blade to track along fine detail and sharp lines.

==Safety First==
[[File:Safety First HD2.png|left|150px]]
There are several hazards you need to be aware of when using a scroll saw.
* Keep your fingers and hands away from the blade and all moving parts.
* If a blade breaks or gets pulled from the holder turn off the machine and tell the supervisor.
* Always wear proper safety equipment to prevent injury.
* Some woods can create toxic dust so be aware of what you are cutting.
* Hold onto material firmly as the blade will try to lift the material off the table.
* Use a brush to clear away chips and sawdust.
* Allow the blade to do the cutting at its own speed. Don't force material into the blade.
* Make sure the material hold down is correctly adjusted. The hold down should never impede the material movement and should barely sit above the material.
==Description==
==Description==
The scroll saw is simple machine with an oscillating blade. The thin shallow blade has a very narrow kerf and allows the user to cut fine details and sharp corners. There are a variety of blades available for various types of materials and cuts. Some of the scroll saw uses include wood puzzle making, intarsia projects, and dovetail cutting. The blade can also be removed and inserted into a drilled hole to give access to the center of an island area in material to cutout the center of an "O" for example.

A paper template with a design can be glued onto the top of a work piece and traced.

The scroll saw has an oscillating blade with a variable speed control. The thin narrow blade allows you to make tight turns and produce very detailed cuts.
The cutting angle of the scroll saw can be changed by doing the following:
1. Release the locking lever by rotating it counter-clockwise.
2. Turn the tilting handle left or right as desired.
3. Use the spring loaded indexing pin for common angles.
4. Tighten the locking lever.

====Demonstration====
1. Obtain a piece of wood roughly 4" x 4". If the work piece is too small it will be difficult to hold onto.

3. Make sure to tension the blade by flipping the blade tension lever. If the blade is not tensioned properly the blade cut will tend to drift and will make it difficult to follow the cut lines.
4. Adjust the height of the hold down and blade guard for the thickness of material you are using.
5. Make sure to tension the blade by flipping the blade tension lever. If the blade is not tensioned properly the blade cut will tend to drift and will make it difficult to follow the cut lines.
5. Make sure the air blow-off nozzle is pointing at location in front of the blade. This will remove dust from the cut lines and make it easier to follow your lines.
6. Make sure the material is clear of the blade and turn on the power switch.

==Troubleshooting==
If the blade pulls out of the holder, stop the machine and contact the supervisor. Over tightening the blade holder will damage the threads.
