Material

Maple, 3 1/2" x 3 1/2"x 12". Exercise. - To turn a plain cylinder 3 inches in diameter, and then to cut it to the form shown in Fig. 104.

Fig. 104.

The cylinder is turned, the divisions are marked on it, and the recesses - are cut in the manner the corresponding operations were performed in the regular second exercise. This exercise differs from the regular one in having the recess at the centre larger, and so giving greater likelihood of vibration if the chisel be pressed too strongly against it. There is no material difference between the operations and those already described.
