The SCMS Station is constructed for 3/4in finished plywood, the t-track is attached to a straight ks spruce 2*4, the case is again from 3/4in plywood, the ends should be at 30 degrees backwards from the front of the positioned saw . The front enclosure and the baffles are for 1/4in plywood attached to the front of the case allowing free movement of the saw @ 90 and 45 degrees/ most of the dust will fall into the shute with the applied suction, there is also upward suction from the saw itself to a secondary suction.
