Thanks everyone for the assistance on this project

After lots of study I decided to go CHEAP.

I bought a $180, 2HP 1phase 110V Central Machinery "dust collector" Tossed the bags and stand in the trash, mounted the blower high on the wall, and blow out the side of the building. Simple and Works great!
I needed to cut off the tabs on the intake port, which were designed to prevent large chunks from hitting the fan, because planing NWC caused frequent plug ups.
Next I need to put a furnace filter in front of a box fan as suggested. Dat ought to take care of the fine stuff.
