I am in the process of scrounging parts to build my bandsaw mill. I will mostly be sawing whitepine as I have lots of large qood quality trees to select from. My question is about using whitepine lumber for roof trusses and floor joist. I worry about the strength of 2x whitepine lumber for this purpose. I will be using the white pine for studs, sheeting/decking and siding which should eliminate having to buy any store-bought lumber for those purposes.
