The jack plane (Figs. 155 and 156) is the first applied to the wood after it has been sawn. This plane is always employed to remove the roughness of the work before finishing up with trying and smoothing planes. It is made up of five parts—namely, the stock (which should be 17 in. in length), the toat or handle, the wedge, the cutting iron or cutter (2 1/8 in. broad), and back iron. Immediately behind the iron is a handle, which, in use, is grasped only by the right hand in planing fir; but in heavy planing, and especially in hard wood, it is necessary to place the left hand across the front of the plane to press it down, to cause the iron to take hold of the wood. When using both hands to the plane, the left is placed with the four fingers lying across the top near the fore end, the thumb passing down the near side. Well-seasoned beech is a suitable wood for the stock. The construction of the trying or trueing plane (Fig. 157) is almost exactly the same as that of the jack plane, but it is much longer, so as to produce truer surfaces. The following instructions on manipulating the jack plane apply equally well to the trying plane.
