Shop-Built Dust Port

by Dan Phalen
Make a dust port for any jig or power tool in your shop

I'll show you how easy it is to build using parts readily available from your local hardware store. And best of all, it really works!

I'll show you how to make two kinds, one for your 2 1/2" shop vac hose, and the other for any 2 1/2" dust collection hose.

Tools you'll need:

  • A 2 3/8" hole saw or Forstner bit
  • MDF or plywood
  • Caliper
  • Gorilla Glue (maybe)

What's The Key?

What makes this dust port so easy is ...a PVC splicer and a toilet gasket.

Yes, this humble toilet tank appliance just happens to be a perfect fit for a 2 1/2" hose or shop vac fitting.

And the second piece is just as easy to find--a 2 3/8 " O.D. PVC splicer, available at most hardware and big-box stores.

Put them together and they work like this.

You get a nice, tight fitting adaptable to your particular dust collection system.

Sample Applications

Here is the dust port applied to a mortise and tenon jig body. Again, the hole must be 2 3/8" diameter to accommodate the PVC splicer..


Below is an angled approach suitable for a router fence. You can build the port housing to suit the dimensions and angle of your particular application. The port below sits at roughly 45 degrees and measures 6"w x 5" x 3.5" high and was glued in place with a synthetic glue that expands to form an air-tight seal.
