I'm going to try this next time. I borrowed the saw from a buddy. It was 10". Not sure about the number if teeth. I used it for my flooring when I did that a few months ago and it worked great. The tape idea sounds like a good one.
I'm really happy with the closet. Tons of shelf space and very sturdy. A physician friend and his family used these recently in their own home remodel. They really do look good.
