==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.

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.
