got a fine mesh animal control vent cover, pretty close to the ideal size

don't want to open that basement window any more than it is for the winter, so installed the mesh cover over the inside!
removed the screen that came w/ the fan, which was right up against the blade, has very small holes like a regular window screen & really kinda cut back on airflow

this greatly increases the square footage of material the air can flow thru, making it easier, plus the holes are slightly larger

def. getting better airflow

thinking I can increase airflow if I open the basement window more, because I think the small opening is restricting the flow. on the test bench the flaps looked more open, but I didn't take any measurements

sure enough, opened the window a cpl more inches. huge improvement in air flow
