A technique I find useful for making an accurate crosscut with a circular saw is to place a framing square on the work and scribe a pencil line at the desired dimension. Then, because I’m right-handed, I slide the square to the left, away from the scribed line. Next I place the saw shoe against the tongue edge of the square and move the two as a unit until the blade lines up with the cutline. With a firm grip on the square, I start up the saw and use the framing-square tongue as a fence, as shown. I get accurate, table-saw quality cuts this way every time.
