PATTERN 3.
Count 40 on the eccentric chuck wheel for each of the three large circles, diminish one turn of the eccentric chuck. Then diminish the circle two turns of the rest screw, and lower the eccentric chuck two turns, and cut a circle every 20 numbers; the others are done the same. For the second pattern of circles, cut one for every number on the eccentric chuck wheel; then move one number on the eccentric chuck wheel, and move the eccentric chuck downwards one turn, and cut a circle every 15; by moving the chuck down, and advancing one number every time, the circles are made to incline sideways. The outer pattern is much the same as in the two former ones.
