Dust separator/vacuum stand

bob.hunter, posted on Feb 21, 2020

Make your stack to fit your specific separator and shop vacuum. I built this stand from less than one sheet of 3/4" maple plywood and a small piece of 1/2" birch plywood. I wanted the vacuum on top for two reasons. First, I'll empty the separator far, far more often than I ever will the vacuum (and I'll likely never need to lift the vac off), so I want to be able to get the separator out easily from below. Second, because my separator has hose ports extending vertically from the lid, I wanted to minimize any airflow restrictions in the hose; putting in this orientation achieves that. 

Materials or Supplies

Materials or Supplies

1 4x8 sheet of 3/4" plywood, 2x4 sheet of 1/2" plywood

Build the legs

I started by building the legs from plywood. I cut them into 2-1/2"-wide strips (length to suit your stack), and then screwed them together to make strong right-angle legs. (I used a 1/8" round-over router bit in a trim router to ease the sharp edges of all parts. Do this to the long edges of the legs after assembly, because you can't do the full length after assembly.)

Add the top and bottom

I cut plywood for the top and bottom; screw them both to the legs.

Add top supports

To trap the vacuum on top, I screwed on short sides, and then added a full-length back (1/2" ply).

Trap the vac and separator

I added cleats to the bottom to keep the separator from scooting off, and another cleat on the front edge of the top to do the same for the vac. Finally, I screwed on swiveling 2" casters to the bottom. Even though I won't roll this stand around a lot, I wanted it to be mobile just in case. Lastly, round over any sharp edges and sand enough to remove any roughness.
