When drilling a ball pin up it would generally have more finger weight.
Bowling ball pin down drilling.
Whether drilling pin up or pin down most of the time drilling the finger holes will only have a slight impact on the ball motion.
The layout when the ball is drilled put the pin 4 5 inches from your positive axis point pap or under your ring finger.
When the pin placement is lowered it is to achieve an arc shape.
Through the progress of bowling ball technology more and more research has been done regarding the placement of the holes in correlation to the pin mass bias marker and other factors that affect your bowling ball s performance.
Drilling layouts are an important part of the ball selection process.
When you drilled a ball pin down it would generally have more thumb weight.
Testing one symmetric ball with one pin distance isn t all that conclusive.
Not to be confused with the pins at the end of the lane every bowling ball is marked with a colored dot which represents the ball s pin.
That said it s an awfully simplistic study.
This caused the ball to get down the lane a bit further.
Methods used to lay out a ball.
Pin down layouts give you a slower more controllable overall ball reaction.
In case you are not aware of the term drilling layout it simply means how and where the holes are mapped out for drilling holes into the ball for gripping purposes in relation to the bowling ball locator pin and mass bias marker.
If you use a quicker response layout higher pin the ball tends to make a more sudden move to the friction so you cannot use a break point closer to yourself.
My experience with the balls ive tried pin up pin down on matches the results of that study.
On a symmetrical ball the center of gravity cg should be in line with the pin angling toward your thumb.
The pin marks the top of the core inside the bowling ball.
The pin is vital in determining how to drill your ball to get your desired reaction on the lanes.
One consideration if you don t have a high rev rate or high ball speed is that you normally want to change to a similar bowling ball with a pin down layout.
What is the pin.
I ve had much better luck getting different reactions out of balls using high low flare drilling s or by using weight holes.
Pin down drilling layouts allow you to stay in the same area because the ball reaction is not as aggressive.
For most performance core shapes in order to change the ball motion measurably you need at least a 1 drill bit going 2 inches deep.
On an asymmetrical ball the mass bias should be in line with the pin and directly underneath your thumb.
Hole size matters as well as a consistent feel.
This section details the different types of layouts that exist and the methods.
