Hey man. Just got your PM and those plates look kinda gnarly. I'd clean those up before going to grain.

As for your flowhood build, the following link will show you everything you need to know. It's all about static pressure and that will be listed on the spec sheet of your hepa. You need a blower powerful enough to provide laminar flow. I forget the exact math, but basically you subtract the static pressure of your hepa from the cfm of the blower, and the proper displacement for laminar flow depends on your filter size. Check this link out.
