When I built an outfeed cabinet for my tablesaw, I wanted it rock-solid, yet mobile, and the same height as the saw. This caster system installs and removes easily, so the cabinet rests solidly on the floor at the correct height.

By installing heavy-duty shelf standards and upside-down brackets, I created a "shelf" that becomes a platform for attaching casters to the underside. I used a pair of 3" swivel casters on one platform and fixed casters on the other.

For the platforms, glue up two layers of 34 " stock (you can also use 112 " stock). I made them 512 " wide to provide clearance for the swivel casters. Cut a 34 "-deep dado near each end to fit each shelf bracket. Trim the brackets to match the width of the platform. To make the brackets more rigid, cut hardwood fillers to fit inside.

Drill into the end of the platform and through the bracket before installing a screw to hold the bracket in place. Mount the casters to each platform and install the wall standards on the cabinet.

To install and remove the casters, use a crowbar to raise one side of the cabinet while slipping the brackets into the slots in the standards.
