About to build a stage, and wondering, what is the purpose of the second layer of wood on top of the stage?
I'm building it out of 2x10s, 16" oc., and 3/4" plywood for the top. I'm planning 2 layers of 3/4" plywood with GG between them, but then I started wondering if this is overkill / does it serve some purpose? Seems the stage will be heavy and strong without the second layer of plywood. On the other hand, it doesn't cost that much, so if it does SOMETHING I'll go ahead with it.
[BTW, hope this post isn't a faux pas, but I'm afraid some questions get lost in my (poorly named) build thread. So I might have to split a couple specific questions out...]
