I'm about to start building a x-cut sled and need some clarification based upon a Youtube video I saw. The sled can do crosscuts, dados, bevels and miters, which is accomplished by the use of replaceable zero clearance inserts. The guy doing the video made a point of saying that the sled is wider on one side of the blade than the other because of the tilt of the saw. It's not clear to me how a left tilt vs right tilt impacts on the build of the sled. Can someone offer some clarification. My saw is a right tilt. Thanks.
