Getting ready to install 8" Pine T&G boards to a vaulted ceiling. I've had the wood acclimating in the room for a couple weeks and I have a Porter Cable Finish Nailer to ease the installation. Boards are 12' and will be cut to a length of a little over 10'.
My main question involves the spacing of the nailing points. I'm going "with the rafters" on this one so I'm going to need to put down some 1x3's perpendicular to the rafters to provide mounting points for the boards. This will also help level things out. The ceiling has a slope to it and I've got the top and bottom mounting strips installed and level.
How many other mounting (furring) strips should I use. Each board will be roughly 10 ft in length (no staggering). Will five strips total be enough? That would give me roughly 24" spacing between the nailing points.
