I just tore down my backyard shed. All that is left is the base/floor, which is plywood. Basically, I want it in small pieces so I can bag it for disposal.
I have a low power Li-ion reciprocating saw with a "green wood" super aggressive blade, which I know can do the job, but I also have a corded 15-amp 7 1/2 circular saw lying around. It is much more powerful, and I know it rips plywood much much quicker and effortlessly.
My general safety understanding of the circular saw is, one side of what you're cutting should not be fastened (free to fall off), or else it may kick back. So, would it be unsafe to run a circular saw through a plywood floor fastened to a wooden frame on the ground?
