>A friend of mine, built a room (I don't remember the exact size, maybe 6'x8' with a sealed door. He drew a vacuum on the room with his big squirrel cage blower. All dust channels came into the room. Periodically, he opened the door and shovelled the debris into trash cans for disposal. If you have room for that extra room in your shop this is a way to do it without passing stuff through the squirrel cage blowers.

>Mark,
A friend of mine built a real handy downdraft table, with a pegboard top sized to fit 2 side-by-side furnace filters (20 x 20 each, I think). He has an internal frame that holds a stack of 3 furnace filters on each side, and even uses a thin layer of polyester batting (used for quilting -- cheap at a fabric store) as an inexpensive pre-filter. The squirrel cage fan is mounted in the cabinet below, and releases filtered air back into the shop, so you don't blow your heat outside. I think he did something to the fan to make it run slower than originally configured.
As far as the filtration goes, this is a bigger version of the ceiling-mounted filter shown on David Ellsworth's tape (#3???) showing lathe and shop modifications.
The advantage of the table is the capability to use it for sanding, and any dust-generating flat work.
Safe Spinning,
