A - Process

There are 3 separate processes that have to be achieved in order to drill a ball for a bowler.

First, we need the measurements for the bowler’s hand, whether that is copying previous measurements, or taking new ones (see chapter – Fitting).

Second, we need to know where on the ball surface we are going to drill the holes (Yes, it does matter). Determining the location of the holes (see chapter – Layouts).

Third, is the process of physically drilling the holes in the ball. We will cover that step by step in this chapter, and we will assume that you already have the measurements and that it has already been determined where you want to drill the holes.
