Workshop Safety

4Safety Tips

Protective Eyewear Always wear protective eyewear as there is a very fine dust

that is thrown by the scroll saw blade and this could cause serious injury if it penetrates the eye.

Mask over mouth and nose The scroll saw makes very fine saw dust that should not be

inhaled. Especially if working with exotic woods. No jewelry or loose clothing

Nothing should be worn that could be caught by the saw blade.

Hearing protection Ear plugs or ear protection of some kind should be worn

any time you are working with loud power tools.

cutting on the downward stroke The teeth on the blade always point

Scroll Saw Blades

Scroll Saw Blades Made to cut various materials such as:

Wood Metal Corian Horn Plastics

Teeth are measured in TPI – Teeth Per Inch


11

Examples of Some Scroll Saw Blades


12

Scroll Saw Blades Skip Tooth Blade

Every second tooth is missing which provides more space between the teeth (gullet) which keeps the blade cooler

Reverse Skip Tooth Blade – For use with Plywood The same as the skip tooth blade except

the last few bottom teeth point upward. This prevents tear out or splintering on the bottom of the cut.


13

Scroll Saw Blades Precision Ground Blades

These are skip tooth blades with small teeth that have been ground to shape. They are sharper, cut straight and leave a very smooth surface. These blades are very aggressive and not recommended for the beginner.

Spiral Blades This is a group of blades that have been twisted

together so that there are teeth all the way around. You can cut in any direction with this blade. The blades are to be used for specialized applications only as they are very hard to control and do not leave a smooth finish.

Applying a Pattern to Wood

Applying a Pattern to Wood


Trace with carbon paper Use spray on adhesive to stick pattern to

wood If removed as soon as the piece is

completely cut out, the pattern usually peels right off. Any residue can be removed by sanding.

For stack cutting or compound cutting on two sides, apply the patterns to the wood and adhere with clear packing tape. The blade cuts through the tape effortlessly.

Compound Cutting

Scroll saw is used to cut 3 dimensional shapes by cutting top to bottom and side to side of the piece prior to removing any waste wood.
