"PUSH" is a reference to the average skid length of a ball past the end of the oil pattern to the breakpoint. Push is basically contingent
on a bowlers speed and rev rate, With Rev Rate appearing to be the dominate factor.

Another potential discovery is that a ball thrown with 350 rpm at about 18 miles per hour appears to be the optimum rev rate. Why? This preliminary research shows that at this rate a bowling ball seems to skid the proper amount to achieve optimum ...

After trying the different methods of calculating the rpm's.

Using a test video.

I've tried counting the rotations as the ball goes down the lane. (gave a result that was 450 rpm.)

Example (this is a new video from Storm to use with their new Matchmaker app page.)


I then tried the USBC method that uses counting 10 frames & how many hours the ball turns (1 rotation = 12 hours). (This ...

CONTROL YOUR ROLL INCREASING/DECREASING BALL SPEED
By Bryan O’Keefe

Bowling is about the ability to repeat shots and the readi- ness to adjust to changing conditions.
Today, we have bowling balls that absorb oil and we compete on an invisible playing field that changes with virtually every shot that goes down the lane. Bowlers need to con- stantly adjust to those

Pinsetter Theory of Operation and Malfunctions

The purpose of this page is to give a bowler a bit more information on what causes a pinsetter stop or malfunction. The
machines are designed ideally to run, X number of cycles, malfunction free. As we all know, and probably seen that is not always
the case. Pinsetters are much like kids, some days they behave and other days you just want to beat their butts. Yes the
machine are old, but the machine are by no means ...

Are you Drilling for your Customer Style?
by Louis Marquez, IBPSIA President

So you know the drill, your customer asks for the strongest drilling angle, you max it out with a leveraged pin angle and some drilling angle degree this by that. Does it work in the bowler’s best interest based off of their PAP distance? Are you combining the fact that the bowler may be of a specific style of player, you should?



Here are some things to consider, first ...

This was a interesting post by John Jameson, of Innovative Bowling (aka ballspinner)


Always remember the power/control spectrum. The ideal situation, that creates the highest scores, is to use as much power as you can effectively control.

More surface = more control

If the lane gives you the control use all the power you can get your hands on that still allows you to hit the pocket consistently.

If the lanes are tough then using ...

RG: Radius Of Gyration.
The RG of a bowling ball tells you how soon the core is designed to roll.
A Low RG ball (aka: a Center Heavy ball) is easier to "rev up", rolls earlier and tends to mean earlier hook, more midlane reaction,a more evenly arcing ball used on wetter conditions.

A High RG ball (aka: a Cover Heavy ball) is harder to "rev up", rolls later and tends to mean later hook, more backend reaction, tends to be more angular.

Rangefinder ® system by Brunswick

It was invented by Lowell Jackson back in the 1930's

"Jackson's poor eyesight was responsible for his most lasting legacy.
Because he could not see the pins well, he would often put a pencil dot
on the approach to help line up. Eventually, a nitpicking official at a
tournament cited the ABC rulebook and made him erase his mark.

That got Jackson to thinking. Out on the lanes, bowlers had long ...

This is a basic example of how you layout a ball using a Dual Angle layout.
Tools used a Pro-Sect Quarter Scale and grease pencil.



The Layout used is 45 X 3" X 30
P.A.P. Location: 4 3/4" Horiz. 1" up Vertical (AKA: 4 3/4"> 1"^)
(The layout will look slightly different actually on a ball, this is just to show the differing parts of the layout.)

Another find from my archive, my look at Applying the Art of War to bowling.

"The Art Of Bowling"

Over two thousand years ago a Chinese warrior-philosopher named Sun-Tzu
wrote a book called The Art of War, it's a book on strategy that can
still be applied and used today and can be used in about any endeavor.

Here we'll look at two thing's: "strategic assessments" and "emptiness
and fullness".
