Add a track to your circular saw
The Kreg Accu-Cut lets a standard circular saw act like a track saw, and it works with almost any conventional circular saw. It has a 53-in.-long track (made up of two 26-1⁄2-in. tracks and connector plates), a sled that mounts to your saw, and a starting block that rests against the edge of the work and guides the sled onto the track. The maximum cutting length is about 48 in. Assembling the tracks is simple, but check the assembly with a straightedge; I had to tweak mine slightly. The sturdy aluminum track has replaceable plastic guides along the edges and strips of nonslip rubber underneath that grab the workpiece, which is crucial, because Kreg deems clamping unnecessary (optional clamps are $15). The guide strip lets you align the cut and helps reduce chipout. Because there are guide strips on both edges, you can use the second one when the first gets worn—just move the starter block to the opposite end. The sled rides with as much as 1⁄32 in. of play, so while cuts are good, they are not perfect. Also, you can’t make bevel cuts. Still, this is an affordable way to turn a circ saw into a reasonably competent track saw.
