This kit allows you to create your own downdraft table. You just need to construct a box from 12mm ply or MDF (plans included), add the table plates and dust port to create a small, benchtop table. The finished size will be approximately 620 x 420 x 160mm. You could, of course, build larger tables by purchasing multiple kits. A full set of 64 grommets and four work supports are included with each kit. A suitable extractor is required, either a 1,000m³ typical bag type with a fine filter or a 1,200W vacuum extractor as a minimum.
