Looks sharp, Bill. The only issue I have with an enclosure of that kind is accessibility. Do you need to crawl in to check on things, or can you remove the stuff beforehand? Why I'm asking, is that everytime I build something like that, it becomes a home for a couple hundred paper wasps with anger management issues. I crawl in, and wham....

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
