JACK-PLANE.

Exercise 6.—Plane continued, and Marking-Gauge.

Material. —Same as before.

Work. —1. To smooth the two planed surfaces of the block with the smoothtng-plane.

2. To mai'k with the gauge for the third side.

3. To plane the third and fourth sides of the block.

The smoothing-plane is adjusted the same as the jack-plane, excepting that its iron is drawn back by a blow on the back of the stock. Its iron should just show, as in h, Fig, 3, Ex. 5, and should remove a very thin shaving. Smooth the face and adjacent side of the block, testing with the try-square, and marking over again the face-edge.

Adjust the gauge, holding it in the left hand, thumb on the head; move the bar so that the marking-point is exactly 3^" from the head; fasten the bar with the thumb-screw. In marking, hold the head in the left hand, thumb against the bar near the point (rt. Fig. 1). Incline the gauge as shown in the figure, until it makes a faint mark; press the head of the gauge firmly against the face-edge, and mark the entire length of the block. Repeat, making the mark deeper, until it is sufficiently distinct. If the head of the gauge is not pressed against the face-edge, or if the point is forced in deeply at first, it is apt to follow the grain, as shown in Fig. 2, where the gauge makes a fault from a to h. Gauge all around 3^" from the face of the block, as shown in Fig. 3.

Plane the edges of the third side down to the gauge-marks, as in Fig. 4; these beveled surfaces serve as guides. Then plane down the middle, being very careful not to go beyond the gauge-marks.

Fig. 5 shows the manner of truing the edge of a board by using one side of the edge of the plane-iron. In the figure, c is the stock, a the high part of the edge. The fingers of the left hand are used as a guide, and pass along the side of the board at h.

Fig. 6 shows one of the best forms of modern planes; its adjustments are made with screws and levers: a and h fasten the iron, c moves the iron sideways, d regulates the depth of the cut, e is the iron, and / its caji.
