Things To Remember
These are basic drillings and are recommended
starting points. However, these balls can be drilled many different
ways and could/should be fined tuned to meet the needs of each
individual bowler. Do no hesitate to adjust the drill pattern to match
the lane conditions and the bowler's personal characteristics such as
ball speed, revolutions and axis rotation.
The illustrations of the drill patterns show the
PIN, CG (Center of Gravity), Extra Hole placement and the PAP (Bowler's
Positive Axis Point). We used a PAP of approximately 5 inches straight
over for the purposes of our illustrations.
Recognize that all illustrations shown are for
right-handers. Reverse drill pattern for left-handers.
Top Weight: High top weight tends to make
the ball skid further and store energy through the front end of the
lane. We recommend high top weight for drier lanes or bowlers with
below average ball speed, medium top weight for medium oil and medium
ball speeds and low top weight for heavy oil or bowlers with above
average ball speed.
Extra Holes: Extra holes are required in
several drillings. We recommend placing the hole on the positive axis
point or one inch past most of the time. Be careful!
Please consider the strength of the bowler's release and the drill
pattern being used before selecting the extra hole position more than
one inch past the bowlers positive axis point.
Static Side Weight: We recommend that all
balls be drilled with approximately Ã‚Â½ ounce side weight to start. If
the bowler wants to reduce back end reaction, gradually remove the
positive side weight.
Surface: the surface of today's balls play
an extremely important role in matching the bowler's needs with the
lane conditions where they bowl. To create the best ball reaction, do
no hesitate to adjust the surface by sanding or polishing. To add
control and move the breakpoint closer to the bowler, increase the
friction of the ball by sanding. To delay the breakpoint and increase
the flip potential in the back end of the lane, reduce the friction of
the ball by polishing.
