Figure 7-11. The first set of holes drilled down the left side of Part O
Drill the remaining holes and then mark the wood for the section to be cut out. Find the center of
the piece (vertically) and draw a line down the center. Use this centerline as the starting point for
measuring and marking the lines where you'll cut away wood from Part O. Figure 7-12 shows the
remaining holes drilled as well as the area that will be cut away (marked with large Xs).
