I guess this brings up the question of how much flow should I try to shove through a 6" duct.
According to this site: Equivalent HVAC Duct Sizes By CFM, it looks like my 6" duct can flow 300 cfm. I think my father in law has an old furnace blower laying around. I think I'll just ask him if he wants it anymore. Anyone know of a way to slow down a 110V AC motor easily?

I'm currently at my in-laws house. My father in law is a master electrician and I knew he'd have something laying around. He just handed me two bathroom vent fans. These should do the job nicely. I'll get pics when I get home. They're about 6" in diameter and the one I'm lookin at now pulls .9A.

Cool! I mean Warm! You could rig it up with a thermostat (maybe from an attic fan) in the attic and another thermostat (for a heatpump or a furnace) in series in the kitchen so that the fan only comes on when the attic is hot and the kitchen is cool.

Yeah, thats what I was thinking. I'll have to dig through the differential temperature controller thread we had a while back. I was looking into making one. Perhaps now is the time, or maybe its time for me to buy a cheap kit and make one for a few bucks.

Farm Innovators Thermo Cube Thermostatically Controlled Outlet
has a model that comes on at 120F and goes off at 100F.. I've been thinking of getting one of these for my attic fan. It's old and it's sensor bit the dust many moons ago. |

For now I might just keep it on manual control. Still working through the details. I'm definitely going to need some flapper door to stop cold air from shooting down the chimney.
