I just cruised over to AVNonline and read the original story. It states that the shot went through 6 layers of 3/4" plywood, PLUS a floor joist. (This coming from Max). Well, I'm even a little more skeptical now. I'll have to redo what I did today, tomorrow with 6 layers of 3/4" plywood and a 2x12.



I just looked at two different sheets of 3/4" plywood. One had five layers of wood and the other had six. You think maybe Max was referring to the layers of wood in the plywood?

I don't think Max is trying to say that he's got 4 1/2 inches of plywood for subflooring in his house. If you need more than 3/4" of plywood, you need more than 2x6 for floor joists. A single sheet of plywood will support anything standard floor joists will support.
