This model is very compact.  The base plate measures 4.5" x 4".  Construction and features are similar to all our bases: machined, anodized 6061 Aluminum and 0-1 tool steel, no castings whatsoever.  In addition to a screw thread adjustable fence/circle cutter,  the base comes complete with plunge springs and two sub-base plates, one of which will accommodate standard Porter-Cable  template guides.   A tower knob for height adjustment, a depth stop and a lever lock are also featured. The small radius attachment and the close work fence are available as accesories for this model.
