How is bowling ball drilling done?


Answer by  Amber40 (24961)

The ball is held in a jig of some kind or by a skilled craftsman in a drill press. A lever is pulled, slowly drilling down into the ball.

Well, they take the drill and shape out a circle. The circles have to be done first before you drill the ball.

When I had a ball drilled, I took it to the store where it was purchased and there was a staff member who was knowledgeable in the process. There was a sample ball with multiple fingers holes. I found a good fit, and the employee drilled the ball based on the sample holes.

Get the measurements for PAP at a bowling ball shop. At home secure ball for safety. Use small hand drill with different size bits, start with smallest drill bit then go to size of bit needed for holes. Shop vac to clean up mess and file to smooth out holes. Measure for comfort, diameter and dept with your own fingers.
