   No, don't try to seal it up, the sawdust needs a minimum air flow rate or else it falls out of the air. You can try covering some of the vents but use duct tape at first, as it could well make it worse. Also flex tube really slows down the air, as do any bends or elbows in it. Some dust remaining is normal, especially in corners where the air flow is slow.

   I don't want to sound like a gadfly here, but why do you object to a small amount of saw dust in the bottom of the saw cabinet?  The bottom of my Unisaw cabinet is sloped toward the port, but a small amount sits in the corners and never increases.  If your cabinet bottom is flat, the dust will form its own sloped profile, much like snow drifting, until the amount doesn't increase (as long as there is enough air moving). 

   Don't choke off any air flow, unless you're getting dust coming out through the wrong places, like the gaps between the cranks and the cabinet, and the table to cabinet interface.  Then you might try temporarily closing off certain vents, raising the static pressure in the cabinet (thereby increasing the flow velocity through the openings that remain), but reducing the overall airflow out the port.  Sorry this isn't much help, but unless the cabinet is shaped to direct the sawdust to the port, short of modifying the cabinet, there isn't much you can do beyond increasing the air flow. 

   Be seeing you...

   Thanks for the info.  I'm new and it just seemed odd that there was a build-up.  I figured it would all be sucked away, thus helping to keep the motor and gears cleaner.  I'm not very nit picky about things being to clean, just one look at my truck will show that, I wanted to see if this was normal.
