This overhead dust collection system was inspired by Dan Pattison. His video is worth watching. https://www.youtube.com/watch?v=XFyGhu43tUU&feature=youtu.be

For me, I decided to make several modifications. I wanted to be able to fully utilize a 2.5” hose, and also have flexibility to use this with a crosscut sled.

The unit adjusts up and down, as well as side to side.

For crosscutting the unit will move on a drawer slide when the sled hits the shroud (see photo 6). It is only necessary to have a few inches of travel. I used a 10” drawer slide and removed the rubber knuckle that holds the drawer slide closed. I wanted something that would pull the shroud back when I pulled the sled back. A spring or even a rubber band seemed too tense. I used a yellow plastic key chain coil. That is working well. I remove it when not in use.

For ripping, the unit can be adjusted side to side to accommodate a full dado stack, or for a very narrow cut. There is a knob on the overhead aluminum tube that can be loosened to move the whole mechanism back and forth on the tube. There is also a small piece of purple heart that is rotated so the drawer slide cannot move.

My Vertical tube goes all the way to the floor. This makes it easier to install.

I also have a separate hose that connects to the table saw dust port. With both hoses I get close to 100% dust collection.

The shroud is made of an acrylic sheet purchased from the orange box store for about $20. A hole was made for a piece of PVC to act as a hose connection. The 1.5” aluminum frame square tubes were purchased online from 80/20 inc.

  • A note about working with the acrylic sheet. Your blades will cut this easily, but don’t cut any safety corners working with it. It does not behave like wood. When cutting acrylic on my miter saw, I held it against the fence with my hand, much as you would a 2×4. The saw yanked the acrylic. The router table also grabbed it when cutting a groove ( i used a fence and stops at the start and the finish). I snapped a bit. When cutting on the saw, hold it down with a piece of scrap wood that spans the length. When cutting grooves on the router table, take 2-3 shallow passes to get through the quarter inch thickness.

Holy drawer slide, Batman! That is smart stuff. I have a cobbled together prototype collector that works ok, and I’ve been trying to figure out the best final way to do it. The crosscut sled has been a big headache to figure out. This is genius.

That is one slick looking unit. Out of curiosity, how much did you sink into it?

My costs on this were $20 acrylic, $10 drawer slide, $42 aluminum tubes, $14 shipping on tubes. The rest was scraps I had around. About $86 all in. Improvising could make this cheaper. I see no reason why the aluminum tubes couldn’t be replaced with wood.

Very nice. I’ve seen this design from the original and liked it. You’ve taken it to the next level. I would like to do the same but maybe make it on a mobile base with the shop vac inside.

Have your say...
