A little brief about Jigsaw
A jigsaw is a saw powered by a motor, with its blade operating in a reciprocating motion. The motor can be powered by either batteries or electricity. The speed of the jigsaw depends on the strokes per minute, determined by the motor’s power and the quality of its construction. It can vary up to approximately 3200 strokes per minute, making it exceptionally fast, and users must exercise extreme caution when operating it.
Circular Cut through Jigsaw
There are several approaches to cutting a circle using a jigsaw. One method involves tracing a circle onto the wood and marking key points along its circumference to guide the jigsaw blade.
First, identify the center of the circle and mark lines from the center to the edge at regular intervals to aid in the cutting process. Once marked, proceed with cutting along these guidelines.
However, it’s important to note that this method may not yield a perfectly clean or accurate circle and could introduce additional challenges.
A more efficient and precise approach involves constructing a makeshift compass and securely attaching the jigsaw to it for cutting. This method ensures greater accuracy and efficiency, considering factors such as physics, cleanliness, and overall workability.
Implementing this technique may require some tool modification and preparation, particularly for individuals working on such projects at home. In the following steps, we will explore how to employ the compass technique for cutting circles with a jigsaw.
Step-by-Step Guide to Cutting a Circle in Wood Using a Jigsaw
Here are several steps to cut a circle while incorporating adjustments with a jigsaw and employing the compass technique.
Step 1.
Initially, we must create a pivot dowel situated centrally within the circle. This dowel will provide support for the threaded rod, which will be affixed to both the pivot and the jigsaw.
To begin, procure a wooden piece approximately 45 cm in thickness. Utilize a bandsaw to precisely cut out a round shape with a diameter of roughly 32 cm.
Using the V-block, create a hole through the center of the dowel to accommodate the coupling nut installation and to provide support for the stick during the drilling process.
Secure the coupling nut firmly and snugly onto the dowel, ensuring a proper fit, and test it before use. Alternatively, screws and stud snaps can be directly inserted into the wood to be cut.
Next, create a countersunk hole on the dowel to accommodate the stud snap, ensuring a better fit onto the workpiece. Optionally, adhesive can be applied to secure it in place.
Step 2.
To create a jigsaw base, we require Baltic birch measuring 0.25 inches in thickness.
Place the jigsaw on the outline, then proceed to cut the base.
Cut it so that the jigsaw fits in tightly. Remove the soleplate at the bottom of the jigsaw.
Next, create openings on both sides of the jigsaw base to accommodate a threaded rod positioned directly perpendicular to its base.
Step 3.
Now, secure the threaded rod to the jigsaw, then connect it to the dowel. Adjust the setup to match the desired size of the cutting circle. Next, affix the dowel at the circle’s center using a stud snap. With the jigsaw, proceed to cut along the marked circle, resulting in a precise outcome.

With a plethora of jigsaws flooding the market, choosing the right one involves considering factors such as power, build quality, noise level, cutting precision, versatility, ergonomic design, power source (battery or corded), battery life (if applicable), blade system, and more.
Above all, it’s crucial to determine the specific requirements for your sawing needs. It’s strongly advised to opt for top-tier options, whether it’s the finest miter saw, cabinet table saw, framing nailer, or any other tool commonly used by both professionals and DIY enthusiasts. Cutting corners on quality could have serious consequences.
