Decorative

Decorative
surface cuts are best described as grooves or patterns formed
on the surfaces of workpieces. Some examples might be "carved"
house number signs, fancy kitchen trivets and accent cuts
on cabinet doors (Figure
22-11).
Usually,
decorative cuts are made with unpiloted roundnose, core box,
veining or straight bits. As a result, you will need some
way to guide your workpiece through the cuts. If your designs
are straight and parallel with the edges of the workpiece,
use the two-piece routing system fence. If they're angled
across the surface like those on the trivet shown in Figure
22-11, you will have to use a scrap piece of stock as a guiding
fixture to "carry" your workpiece through the cuts. Simply
attach your workpiece to this piece of stock with double-stick
tape or nails. Then, guide this fixture (with your workpiece
attached) against the fence to make your cuts (Figure
22-12). Warning: If you use nails to attach your stock
to the guiding fixture, be sure they are not in the path of
the bit.

To make straight, diagonal cuts across the surfaces
of projects, attach your workpiece to a fixture at an
angle and guide it against the fence.

Un-piloted bits ilke this ogee bit can be used to shape
both sides of the groove when making raised panel-looking
doors.

You can
also use unpiloted edging bits such as an ogee or corner rounding
bit to form fancy grooves in workpiece surfaces with shaped
cuts on both the left and right of the bit (Figure
22-13). This technique can be used quite effectively to
produce raised panel-looking cabinet doors from a solid piece
of stock.
If you're
cutting grooves on the surfaces of round workpieces, you can
use V-shaped fence faces (Figure
22-14) to guide the stock or use the pivoting pin technique
described earlier under "Full Edge Removal".

When making
free-hand decorative cuts on irregular-shaped workpieces,
it's important that you take multiple light passes to avoid
grabbing and provide improved control.
The most
accurate method of forming irregular-shaped decora-tive cuts
is with a guiding fixture. Specific information about making
and using fixtures can be found later in this article.
