Hood looks awesome. I am highly reconsidering re-designing mine and going with something more like yours.
Couple more questions about it. First, how did you mount the 1/2'' plywood "hood" to the 2x6 base and top? It's hard to tell in the pics. Second, how do you plan on mounting it, looks like you mounted some rings to the 2x6? Finally, any chance you would be willing to disclose the dimensions on the 1/2" in plywood (i.e. the width at the bottom and top)?
