Below are instructions on making a small machine for grooving, rebating, and moulding sashes and similar woodwork. Fix together a strong frame aw for a small hand circular-saw bench. Two bearings secured to the frame may carry a spindle with a grooved cutter-head D (Fig. 1). On the frame is secured a portable table, hinged at one end so that the other end maybe raised; or it can be raised both ends to vary the depth of cut; or it may be screwed to the frame, and the cutters adjusted by easing the studs that secure them to the cutter-head, the studs being screwed into tapped holes in the head. A (Fig. 1) is the spindle, and at B are tight and loose pulleys, and at 0 the parts that run in the bearings. These should fit nicely and run freely. Fig. 2 is an enlarged end view of the cutter-head, showing the cutters E secured to the head.

At F are the studs that secure the cutters to the head. There should be a suitable opening in the table for tbe cutters to pass through, and two small pressure rolls immediately before and behind the cutters to bear on the stuff to be worked. These cutters should be driven at a high speed. The higher the speed, without vibration, the better the work done. In the same bearings a saw spindle carrying a small circular saw may run. The table and spindle referred to above should be removed, and another table with a saw-gate in it for the passage of the saw should be screwed on the frame. Suitable saws may be used for tongueing and grooving, or cutters, as Figs. 3 and 4, may be secured to the cutter-head. When grooving, use a long fence, to which the pressure rollers should be secured. Suitable cutters for moulding, grooving, etc., may be obtained from makers of woodworking machinery. The work in such a small machine may be fed by hand.
