That is awesome, and looks pretty danged easy to build. You are absolutely right that it would have saved me some heartache and cash, however, I already am going down the road, might as well finish now. Hey, at least I asked about the 1" pipe before using it ;-), do I get half credit there? So... I am taking back the 1", searching for 2". Swapping my huge blower for a smaller one and I need to make sure I put an air gate of some sort. As for the air gate, do I 'need' this or can I get a rheostat type of device and just control current to the fan?
