A yellow, DeWalt circluar saw setup to cut a couple inches off an m.d.f. board. Another piece of wood is clamped to the m.d.f. to act as a guide rail. The wood and saw are on top of long pieces of foam placed on the floor. the foam provides space for the saw to opperate. An orange triangle is in the foreground next to a small notebook, a pencil, and a measuring tape.
This is my old setup for cutting with a circular saw. I use a Festool setup now. This worked great though.
