This is in response to a question by Rusty Tools...
Cull lumber is essentially lumber that doesn't pass inspection for it's desired grade. Instead of dropping the grade, the stores would just knock 70-80% off the price. In my case I would buy 1x8, 1x10 and 1x12 pine boards with lengths up to 14' from the "cull lumber" stack at HD (most lumber yards have one). I would get these for next to nothing, some for free. Some might have a split in one end or a few knot holes. I ripped them down to make my own 1x4 for framing. I also scored with a fair number of western red cedar, which got resawn down for my siding and other areas.
Wiley Windows are actually an ancient design for boats. You'll find many threads on these. When done right they are water tight in even the strongest wind/rain conditions, can be in an open position during extreme rain storms or can have the "glass" removed for full opening. There are no moving parts. Think of a jalousie window that is upside down, with a permanent side frame and is open to the inside.
