1throughout), and are used by placing them between the points of one end of the callipers whilst the other end gauges the thickness of the plate.
3At the distance of 6 1/4 inches from the upper or wide end of the back upon the centre line, make a mark with tracer, and from this, as a starting-point, measure off 2 3/4 inches towards the upper end, and 2 inches towards lower end upon centre line of back; set a small compass to 3/4 in., and set off this from the extreme or end marks on each side, thus forming a rectangular figure 4 3/4 in. long and 1 1/2 in. wide.
5The thickness within this figure must be reduced until it is the same as No. 1 or 1/6 of an inch thick throughout, gradually but accurately decreasing in thickness outwards to 1 2/3 lines midways between this and the edges where the sides are placed, this part being 1 1/4 lines thick in the back. The back may be hollowed out with gouge or draw-knife described, until the thickness is nearly arrived at, after which the small plane may be used until the precise thicknesses are obtained. A line should be run round the inside margin of the back with gauge at the place whereon the side linings will run, and the thickness truly reduced to the standard at this part.
7The graduating of the thicknesses must be wrought very accurately, and the interior surface finished with the same care as the already finished outer arched surface—no ridges or irregularities being left, but all smooth and finished.
9The final finishing must be done with No. 0 sand or glass paper. It must be observed that the outer
