If the rafters are the same wood as the Queens house is framed out of it's black Walnut. It grows wild on the land here. When I start working up there I'll take a better pic.
As for the Service entrance I'm lucking out there because it already exists for the barn so all I'm doing is updating the breaker panel. The REC here is a joke the C stands for cooperative which means we have to cooperate with them to get any thing done. Azzholes!

I was going to put in a 200 Amp panel but after thinking about it I only have 5 220V tools and only 2 of those are ever ran at the same time so I'm good to go for now. In the future i may upgrade to more industrial quality tools and then I'll just have them bring in true 3 phase. (Gawd Forbide)
