Alternate means to attach ceiling
I'm trying to limit the amount of height I sacrifice when I install the ceiling, as I'm 6'1" and the ribs are 6'2" off my floor. With shoes if I stand upright, I'm brushing the roof ribs. I'd rather not attach the ceiling directly to the ribs (I'd need about twice the number of panels due to how I'd have to cut to fit), and that still wouldn't solve the issue of attaching one planned wall that will be about 10" from the closest rib.
My thought is to use 2x3s or 2x4s running perpendicular between the existing ribs as stringers, attached to the ribs with pocket screws so I don't end up any lower than the ribs. Can anyone think of a good reason why this would be a bad idea? This gets my ceiling as high as possible and allows me something to attach my walls and ceiling to, regardless of whether there is a rib where I need one or not.
