Downdraft / Rolling Tablesaw Storage Cabinet

Here is my rolling tablesaw cabinet. I wanted to have some dedicated space to store my tablesaw accessories, so I built a cabinet 31-1/2” high, with a 28-1/2×28-1/2” top. The cabinet is sized to roll under the wing of my tablesaw. It has a small but deep drawer on top, and two doors for storage below. It is great to store my router, biscuit jointer, and sander without the bulk of their factory storage containers. The wheels are ridgid double 4” casters in the rear and total lock pivoting casters up front. The height is perfect to sit on a rolling stool and sand, do layout work, or small assembly projects. A Rockler tool port and a v-shaped vacuum chamber allow this cabinet to moonlight as a downdraft table. Seal the chamber with silicone during assembly. I drilled 3/8” holes in the top, spaced 1-1/2” apart at the drill press. For the holes that the drill press couldn’t reach, I used a hand drill with guide block and an Emerson straightedge clamp. The total area of the downdraft surface is 13”x22” which is about right for my 650 cfm dust collector. Make sure all the holes are above the chamber, and not above the drawer. The v-shaped chamber helps direct sawdust toward the dust port. Rockler has plans online for a dust collector box. I didn’t want to lift the box up and down on a cabinet, so I simple incorporated it into a multipurpose cabinet. When sanding, your workpiece covers some of the holes, so the suction is pretty good. It works great and really keeps the dust out of the air.

EDIT: I later added 3/4” holes to improve suction, and it works great. If I had it to do over, I would skip the 3/8” holes and just use 3/4” holes. As a bonus they work for bench dogs.
