A woodworker needs to make an internal rectangular cutout in a wooden panel using a handheld jigsaw (saber saw). What is the correct sequence of steps to perform this cutting operation safely and accurately?
- 1Mark the cutout dimensions onto the panel and apply protective masking tape along the cutlines to minimize surface splintering.
- 2Drill a starter pilot hole inside the waste area adjacent to the cutline, ensuring the hole diameter exceeds the jigsaw blade width.
- 3Place the jigsaw base shoe flat on the workpiece with the blade centered freely inside the pilot hole without contacting the wood.
- 4Squeeze the trigger to bring the motor to full operating speed before feeding the blade smoothly forward into the cutline.
- 5Support the center cutout piece from underneath as the final section is cut to prevent workpiece tear-out and blade pinching.
Answer
The correct operational sequence begins with laying out the cutline and applying surface protection, drilling an internal pilot hole in the waste stock, seating the base shoe with the blade positioned freely inside the hole, starting the motor to full speed before engaging the cutline, and supporting the waste piece through the final cut.
Making an internal cutout with a portable jigsaw requires establishing layout lines first, creating an entry clearance hole strictly within the scrap/waste area, resting the base shoe flat while keeping the blade free from stock contact, accelerating the motor to full speed before cutting into the line, and supporting the waste core at the conclusion to avoid pinching and fiber tear-out.
