Patterns & Layout

Full size patterns for scroll saw projects are available in magazines and books as well as from commercial suppliers who provide letter templates for signs or complete project plans. If your plans are not full size, they can be enlarged by methods such as the grid system (Figure 15-3) or by using a pantograph (Figure 15-4).

Another very effective way to produce full size patterns is by using a copier machine which can enlarge and reduce. By making an enlargement of an enlargement, small drawings can be quickly and accurately increased to many times their original size and the cost is minimal, even if several copies are required.

 

The full size pattern can then be transferred to the stock in several ways. For light colored wood you can use carbon paper or trace around a heavy paper cutout of the piece. On darker woods or for very accurate work it is usually easier to attach the pattern directly to the stock before cutting (Figure 15-5). This can be done with a thin coating of rubber cement or with a spray adhesive.

After the stock has been cut, you can easily remove the pattern by belt sanding. If the pattern is reversible, you can even leave it attached to the back side of the project. In either case, the pattern will be destroyed, so you will want to make copies for duplicates or in case of cutting mistakes.
