I bought a circular saw recently. I noticed that sometimes as I finish a cut, the saw throws the free end of the board forward a couple of feet. Most of the time, the board just drops as expected, but every now and then, it gets projected. It doesn't seem like a huge deal, but I was curious to know if there is a technique to prevent this.
The wood I am cutting is SPF. I believe I've usually seen this happen when I am cutting off smaller pieces, from 2" to 12" in length. I am making crosscuts across boards that are 2" to 3" wide, and I make the cut in about 1-2 seconds.
