Sawdust Behind My SawStop

One reason for owning a Cabinet Saw is the efficient collection of saw dust generated by the tool. After using the saw for a few months I noted that while most of the sawdust generated was evacuated by my dust collection system, the floor behind the saw was always loaded with sawdust. I wanted to solve this issue.

On examination sawdust was being blown over the rear of the saw chassis and the surrounding cabinet. A temporary cover over the space on top of the back of the saw resulted in a buildup of sawdust on the rear trunion bracket and surrounding assemblies. The right solution was to collect the sawdust as it came out of the saw.

I fashioned a box (plenum) the width of the saw cabinet to fit under the rear fence rail. The box is open to the opening over the rear of the saw cabinet..A magnet glued to each end helps to hold the box tightly to the cabinet.

To extract the sawdust a 2 inch dust hose is fitted to the bottom of the new plenum. It connects to the 4 inch dust hose directly below the plenum attached to the rear of the saw cabinet. A Rockler “Dust Right” Router Table Dual Port dust fitting provides the junction in the 4 inch dust hose.

The “Dust Right” attaches directly to the dust port on the saw: the 4” hose to the “Dust Right”

The long closed side of the box is fashioned from 5/4 wood. This allows two bolts to secure the box to the rear fence rail..One of the bolts secures both the added plenum and the out feed table for the saw as well.
The result of adding this small plenum to the rear of the saw is the elimination of 99% of sawdust collecting behind the saw.

I have the same problem.
Thanks for share a clever solution.

Do I see telescoping legs on the outfit table?
If so, were successful in designing a mecanism to fold them when the outfeed table is not in use?

thanks for sharing.

I’ve got the same problem. I always thought it was coming off the top. Good eye!

That’s why we’re all here…... So you more experienced/wiser guys can show us kids of all ages how to fix such issues. Now, we, the less experienced guys and gals just need to grow tired enough of our problems to implement your solutions.
Nice work and great thinking.

-- Cheers and God Bless

I emailed wichle, and he sent me the pictures to post. Also, I take the liberty of quoting some more info from him here:

“The plenum is open on the top and the side toward the saw. The ends have to be cut to allow a little of the tabletop casting so the plenum fits tight to the saw case. You might put a small bead of caulk between the plenum and the saw if it leaks.”

Dust piling up behind the saw:

Plenum clamped to rear fence rail:

Plenum plumbed into main saw hose:

Rockler “Dust Right” router table fitting:

Plenum with outfeed table:

Shame it came to that on an expensive cabinet saw, but it sure looks nice!
