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.

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.

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
www.woodworkingtipsforwomen.com
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.
