My shop is a one-car garage and it can get pretty dusty when I grind things. I have an old furnace fan mounted on a piece of plywood. When I am doing something dusty or when there are fumes, I open the garage door and turn on the fan. That furnace fan was intended to move air through a whole house. It really airs out my shop in a hurry. You might be able to get an old furnace fan from a heating company for a few bucks.
 
Anyone ever used a squirrel box fan for a dust collector?? I've got a couple, and was thinking of using one for dust collection. Take care! Michael

L6- a friend use to use one for his big 6x48 beltsander he hooked it up when he flat ground blades and stag for his handles. He had it plumbed through the out side wall and blew it out side ... it sure kept the stag smell down in the shop.

Darrel has the right idea. I built a 1/2" plywood box, with two open sides to fit 25x18" furnace filters to. I then mounted the box to the ceiling of my shop (I have a "half loft" in my shop) with the exhaust pointing straight up. It sucks up the dust, and expels cleaned air back into my shop. During the winters around here, opening the shop doors at -30 makes for a pretty frigid work area.

If you check out the WOOD MAGAZINE website, they have plans for a dust system using the attic fan motor, 1/2 inch plywood, and 5 21x21 furnace filters.

The one I built works really well. Added wheels, a spring to hold the top closed and a shut-off switch. I throw away the first filter about once a month, move the others all back one space, and add a new one in the front. The filters are about a buck at the big home centers.

It moves easily, is easy to turn on/off, and is really low maintenance and dirt cheap to run.

I keep the blower in the center of the shop, pointed away from where I am working. It picks up all the gook being generated, traps most of it, and sends the rest to the off side of the shop, away from me.

This is about a hundred to one return on your effort to build. And it really helps with the bone and antler and stag odors.
