Instant conversion: tablesaw to downdraft table
Here's a quick and easy way to add a downdraft sanding table to your dust-collection system. Cut two pieces of hardwood to 3⁄4 ×11⁄8 ×18". Then cut two crosspieces from 3⁄4 " stock and assemble the frame, above, topping it with perforated hardboard.
Lower the blade on your dust-collector-connected tablesaw, remove the throat plate, and center the downdraft table over the opening. Turn your dust collector on, and you've got an instant downdraft table perfect for sanding small parts.
