Project Information

I had some scrap MDF, ply and peg board laying around, so I figured I'd throw together a downdraft sanding table. It is an extremely basic build and I just used brad nails and glue for all the joints. The size is fully configurable to meet your needs, I'm actually going to go back and make a larger one later I believe.

Nice build. Does it work as well as you thought it would. I was a little disappointed that mine didn't suck dust as much as I had hoped, but still keeps a lot of dust out of the air.

you do not have large enough holes to be effective, enlarge them and see what happens.
how many cfm is your dc?

Thanks, Robert! It actually does a great job for me. I have it hooked up to a 1200 cfm dust collector and it does well. One thing that really made it work great was adding temporary sides to it when sanding. I have 1/2" plywood that I put along the sides to make about a 6" wall on 3 sides. So anything that is going to fling out hits the wall and slows down enough for the suction to grab it. Without the walls it's still effective, just not 100%.

Does not really matter size of dust collector since you have a 2.5 inch hose connected and that limits flow.

I built a similar one and matched the area of the holes to the area of the hose to take best advantage of the dust collector. I also used different diameter holes in certain locations to improve performance.
