Coping Saw Tips
by Rick Oconnell
Coping Saw Tips is used for delicate ornamental and filigree work, cuts curves smaller than pencil diameter (Spiral types are even slimmer.)
Types are available, much smaller than can be cut with a compass able for cutting wood, plastics, and thin metal. To or keyhole saw. Its replaceable blades, usually 6 to change blades, turn the handle to loosen the 634 inches long, depending on the saw, may be as threaded .mounting grip, while springing the saw frame ends together between your body and the workbench.
With frame ends sprung inward, the old blade can be removed and a new one inserted. Slant of teeth depends on how the work is to be done. If it will be inounted vertically in a vise, the teeth should slam away from the handle, as you will be cutting. on the push stroke. For exacting, delicate scroll work, the teeth should slant toward the handle, as you will be cutting on the pull stroke. The blade can be turned during the work, without removing it from the frame, to keep the frame clear of the edge of the material as the cut changes direction.
Depth between blade and back of frame is usually from 41/2 to 61/2 inches. • Saws with frame depths of 8 to 12 inches are some-times called scroll saws, fret saws, or deep-throat coping saws. Their blades are mounted with teeth slanting toward the handle to cut on the pull stroke, reducing the chance of blade spring-out.
Typical compass saws have 12- to 14-inch blades with 8 or 10 teeth per inch. Keyhole saws have narrower blades, usually 10 or 12 inches long, with 10 teeth per inch. Either can cut curves, though keyhole saws cut smaller diameters than compass saws. Both arc also suited to making either curved or straight cuts start-ing from a bored hole. Since they are not frame types, they are not limited, as a coping saw is, to working near the edge of a panel. Hence, they can be used to cut openings in floors or walls for pipes or electrical outlets with the cut starting from a bored hole.
When starting from a hole, use vertical strokes to begin. As the cut progresses, bring the saw to about a 45-degree angle: When you are starting a cut from, the edge, the saw can be at that approximate angle from the beginning.More basic carpentry tips coming in the near future stay tuned.
