Workshop Exercises with a Compass Saw
A common joinery task is cutting an opening in a plywood panel, such as a letter box slot or a hole for a switch box. Students mark the outline and bore a starting hole inside it with a flat bit from the Center and Flat Drill Bits Set. They saw out along the line, then clean up the edge with a Half Round File and a Sanding Block.
Teachers can set the compass saw beside the Coping Saws to compare two ways of cutting a curve. A coping saw holds a fine blade in a frame, so the frame depth limits how far in from the edge it can reach. The compass saw has no frame and can cut anywhere in a wide panel once a hole is drilled.
Frequently Asked Questions
What is the difference between a keyhole saw and a compass saw?
Both have a narrow, tapered blade on a handle with no frame, for cuts that start inside a panel. The keyhole saw is the smaller and finer of the two, for tight curves and small openings. A compass saw has a slightly wider blade for longer curved cuts.
How do I start a cut in the middle of a board?
Drill a hole inside the waste area, large enough to take the tip of the blade. Push the tip in, then saw with short, steady strokes and turn the blade slowly as the line curves.
What materials can it cut?
These saws are meant for plywood and hardwoods, and the triple-ground teeth leave a fine finish. Softwood cuts easily too. Metal needs a Hacksaw and its own fine-toothed blades.
Why does the blade bend or bind in the cut?
A thin blade bends when it is forced or twisted to follow a tight curve. Let the teeth do the work on the push stroke, keep the blade upright and drill relief holes at sharp corners.
How is the blade held in the handle?
The blade is fixed into the one-piece, bi-material handle with heavy-duty screws. If it works loose after long use, tighten the screws so the blade does not wobble in the cut.
