Tonight, I finished the last of my shop projects (for now ). So the next thing I do will actually be a "real" project.
With the recent addition of a DC in my shop, I decided to make a down draft table. Seconds after coming up with the idea it hit me, I don't have room in my shop for a table. Still wanting a down draft for sanding, I came up with this..... a down draft box that sits on my workmate. To set it up I remove the center piece of the workmate's top, set the box in place. Then I hook up the 4in dust hose to the port on the bottom of the box. when I am done, The workmate folds up and the box can be put in a corner out of the way.

On to how I made it....
Esentially it is a pine box held together with pocket screws. There is a upper support structure to support the table top, and a lower support structure to support the plastic dust port. The dust port is a 14in square table saw dust hood from Rocker. To fill the space in between the dust hood and the sides of the box, I used aluminum flashing that I cut to size and screwed in to the box and support structure. I sealed the seams of the flashing with duct tape. The top is peg board, that is attached with screws. I drilled out roughly every other hole on the peg board to 3/8in. When I initially fired it up before enlarging the holes, the small peg holes made a loud whistling sound. As soon as the holes were enlarged the whistling dropped right off.
Edit: I do have to say that I used my new "Super Sled" for a good portion of this and it worked great! I used the extended stop block, and it worked exactly as designed. I also used the Super Sled to cut all the dados seen in this project. It really helped keeping everything exactly the same.
