I could not imagine how challenging it must be to work out of a basement shop. The thought of moving big machinery down the stairs is daunting enough for me (one of my friends managed to get a SawStop PCS into his basement with only one extra helper).
My basement (walk-out) is a place to store my lumber (on a pool table), but in the winter time when it is snow everywhere, I will try to move the lumber via the stairs -- doable with a bit of care. 4 x 8, if any, probably won't work and must go through the basement door. But then, I usually have a full sheet pre-cut into two at the lumber yard or big box store.
