3.

 

Keep records of each cut you make in the process on your drill sheet as you should be 

able to duplicate any cut you make at anytime on any ball 

 

4.

 

First oval customers may not like the feel as the purpose of the oval is get grip pressure 
on the pad of the thumb and fingers for better control and feel.  So be sure you explain 

properly up front with first time customer 

 
5.

 

Done properly can keep customers coming back for  many years 

 
6.

 

When drilling the first oval for a customer we recommend that they are there for the 

entire process as you can be more accurate, after the first one the Mill Drill machine will 

allow you to recreate or duplicate each step as long as you noted each move on your 
spec sheet.  GOOD NOTES ARE EVERYTHING!!! 

 
Section (4b) Determining the Proper Angle 

 

 

There are many ways to determine the angle for an oval hole.  The simplest however is 

by using a Pro Sect Lay out tool.  This tool has a straight edge for drawing the center lie but 
also has a protractor ring attached as part of the tool.   

 

1.

 

First mark the center line of the grip on the ball you are using. This will be a line that 

runs between the fingers and thru the thumb. It is best if this is an existing ball the 

customer is using Next place their fingers in the ball and slide the thumb into the first 
knuckle.   

 
2.

 

Take a yellow pencil and mark a line on the ball that follows the knuckle of the thumb. 

This is the true angle the oval should be cut on 

 
3.

 

Next take the Pro Sect and align the flat part with the line you made and slide it up to 

the center of the hole.  When in this position look at the protractor and read the degree 
that is on the center line of the grip 

 

4.

 

Take this number and mark on your Drill Sheet 

 

Section (4c) Determining the Width of the Hole 

 

 

Again there are many ways in which this can be done and as you become more 

proficient in drilling ovals you may even find a new way.  However the following is 

recommended for the Mill Drill machine as it has been proven to be the simplest method.
