Yeah, amazingly this ceiling has no discernible sag despite the fact that they used 2×6s at about the maximum span. Looks like #2 doug fir but could possible be YP which has a longer span rating. Because of the size of the hole I’m going to need in the ceiling to get this done, it would also be possible to “gusset” the cut ends to the roof rafters. At the one end the bottom of the roof rafter is only about 4 inches away from the top of the ceiling joist. At the other end it’s more like 8 to 10 inches.
Just checked…. the roof rafters are 2×6 as well. That’s a heck of a span for a 2×6. I’m probably over-thinking this with the gusset idea (I am the king of over-thinking, stressing and then overbuilding). It’s 1 joist to cut. The thought behind the gusseting was that the range hood could weight 50 pounds (or 80) and I don’t want to induce sag over time by hanging something that heavy from the ceiling. I wish they’d used 2×8s, but that’s out of my control at this point. The gussets would have the roof rafters sharing the load.
I think I just talked myself out of the gusset idea :)
