Abstract: An improved wood working facility has a table saw which is operated in combination with a table saw extension table. The extension table is provided with an array of orifices through which air is ejected to provide a buoyant support for boards and sheet material laid atop the extension table. An ordinary shop vacuum cleaner may be utilized as the source of air being expelled from the orifices. Air may also be received from a distribution system in the shop which distributes compressed air to the various machine sites. The air is provided to an air plenum below the extension table top and exits from the plenum via the multiplicity of orifices in the top of the table. A low surface frictional veneer on the table top adds to the effort reducing efficiency of the extension table.
