Procedure

Step #1
Choose a Layout based on desired ball reaction.
(EXAMPLE: 4x4 means a pin 4" from the PAP and mass bias 4" from the PAP. This layout is very aggressive.)


Step #2
Picture of Step 2 Draw an arc around the pin that corresponds to the desired pin to PAP distance.


Step #3
Picture of Step 3 Draw an arc around the mass bias that corresponds to the desired mass bias to PAP distance.


Step #4
Picture of Step 4 The intersection of these two arcs is the location of the PAP.


Step #5
Picture of Step 5 Choose the desired pin buffer distance and draw that arc around the pin.
(You will now have two arcs around the pin and just one around the key).


Step #6
Picture of Step 6 Draw a line tangent to your second arc and through the PAP. This is your PAL


Step #7
Picture of Step 7 Measure backward from PAP to determine grip midlane and center line.
(EXAMPLE: If PAP is measured to be 5" right and 1" up, then measure down 1" along PAL and 5" left. You have now located the grip center.)


Step #8
Drill and scale the ball to determine if the need, if any, for an extra hole.

Balance Hole Location Guide

Extra Hole Placement:
On the PAP
Will Produce earlier roll and a smoother break point.
Off the PAP
Will produce much earlier roll with increased hook potential.
For heavy oil and players with low rev rates, always use layouts that utilize an Extra hole for a stronger ball reaction.

Storm Warning

High rev players should use extra holes located no farther from the grip center than the PAL. Also, for these players, consider using a smaller drill bit (7/8" and down) and drilling deep to remove excess weight.

A Diagram of Extra Holes On the PAP A Diagram of Extra Holes Off the PAP

Learn Just The FACTS!

  • It's okay to drill into the engraved KEY (Mass Bias Marking). It will actually enhance the ball reaction.
  • It's important to scale the ball for static balance determination, If excessive side weight and/or finger/thumb weight is present, draw a line from the grip center through the CG and extend to the Perpendicular Axis line. Mark this spot and drill appropriate extra hole.
  • Always keep the KEY (Mass Bias) at least 2" away from the bowler's initial ball track, towards the bowler's PAP.
  • It's okay to drill into the pin, as long as you drill out the entire pin. If you drill out just a portion of the pin, or drill too close to the pin, you will create a weak portion of the shell which may ultimately result in fracturing of the coverstock.

Definitions

A Diagram showing how to locate the Pin Buffer
Pin Buffer
Horizontal distance between pin and perpendicular axis line. Determines the 'Angularity' of the ball motion (Smaller distances increase backed reaction)
Perpendicular Axis Line (PAL)
The line that runs perpendicular to you grip midline through your Positive Axis Point (PAP)
 
Please Note: Because all bowlers have different positive axis points (PAP) your layouts may not have the same appearance as the illustrations. Also the layouts are for right-handed players. Remember to flip or rotate to produce "mirror-image" for left-handed players.

Advanced Drilling Instructions

Advanced Drilling Legend

Layout 1

Storm Advanced Drilling Diagram 1
  • Locate the mass bias by drawing a line from the pin through the CG. Find the location 6 3/4" from the pin along this line, and mark it with "MB". This is the location of the mass bias or the secondary pin
  • Place the major pin 5" from the player's PAP and place the "MB" on the player's ball track next to the thumb hole
  • Use this layout for length with a medium backend reaction.
  • This layout is great for medium to light oil. Also works well for players with higher rev rates.

Layout 2

Storm Advanced Drilling Diagram 2
  • Locate the mass bias and mark it with "MB"
  • Place the major pin 4 1/4" from the player's PAP and locate the mass bias (MB) along the player's PAL
  • This layout will most often require an extra hole, so place this hole on the PAP and remove excess side weight to "0".
  • This layout works well to produce medium length and heavy midlane roll. Usually works well on medium to heavy oil, especially longer oil patterns.

Layout 3

Storm Advanced Drilling Diagram 3
  • Locate the mass bias and mark the spot with an "MB". Remember, the mass bias is a fine tuning device used by advanced players.
  • Place the major pin 3-3/8" from the PAP and locate the mass bias halfway between the player's ball track and PAL
  • Place the extra hole, if necessary, on the player's PAP, removing excess side weight to less than 1 oz.

Note: This is a "High Flare" layout that should only be used by low rev players seeking maximum ball reaction!

Layout 4

Storm Advanced Drilling Diagram 4
(For this layout we will select a ball with a pin distance of 2-5" from the CG)
  • Place the major pin 1 1/2" from the PAP. Remember to keep the pin along the line located between the PAP and the player's finger holes.
  • Place the mass bias in the player's ball track.
  • Check side weight to see if an extra hole is necessary. If so, place the hole on the PAP.
  • This layout will produce heavy roll with a controllable backend reaction. Players with extensive side roll or high rev players will love this layout to help control dry, short oil patterns with very dry backends

Master Drilling

Note: For reaction adjustments, consult the Ball Surface Reaction Guide. Be sure to check for excess side weight and finger/thumb weight, as a balance hole may be necessary for any of these layouts. If one is required, draw a line from the center of the grip through the CG and extend to the PAL. This will be the location of the balance hole.
Storm Master Drilling Legend

Layout 1

Storm Master Drilling Layout 1
  • With this layout, we place the pin 5 3/4" from the PAP, above the finger holes, to produce length on drier conditions.
  • Next we select a mass bias, MC2, position suitable for our desired breakpoint shape.
  • (A) Mass Bias in the ball track - designed to prodce a late and smooth breakpoint
  • (B) Mass Bias in the Strong Position - This will produce an earlier and sharper breakpoint than position A. - Good for extreme entry angle!
  • (C) Mass Bias on the PAL - produces the earliest breakpoint of the three positions while providing a controllable and "readable" backend. - Works great on heavy oil patterns!

Layout 2

Storm Master Drilling Layout 2
  • With this layout, we place the pin 4 1/4" from the PAP. This position will produce medium to high flare, great for players trying to "open up" on a medium to heavy oil lane condition.
  • For bowlers with medium to high rev rates, this in position will often produce the most overall hook throughout the entire lane.
  • Now select an MC2 position:
  • (A) Locate the Mass Bias halfway between the ball track and PAL - designed to produce a sharp breakpoint
  • (B) Place the Mass Bias at the PAL for an easier, smoother, breakpoint.
  • (C) Place the Mass Bias 2" past the PAL for a very heavy midlane roll on long oil patterns.

Layout 3

Strom Master Drilling Layout 3
  • With this layout, select a ball with a pin 3 - 4 1/2" out from the CG.
  • Place the pin 2 1/4" from the PAP.
  • Locate the MC2 on the players ball track.
  • Weigh the ball to ensure static balance is withing 1oz in both left/right and finger/thumb directions. For this particular layout we will not use a balance hole.
  • This layout will produce an early roll, a minimum amount of flare and works well for controlling conditions with dry backends.

Layout 4 - For Full Rollers

Storm Master Drilling Layout 4
  • For players who track between the fingers and thumb (full rollers), place the major pin 4 1/2" from the grip center in the southwest direction.
  • If a weight hole is necessary, be sure to locate it 6 1/2" from the grip center in the direction of either the major pin or MC2 pin.

Basic Drilling Instructions

Storm Basic Drilling Lengend

Layout 1 - Label Drilling

Storm Basic Drilling Layout 1
  • This layout is considered to be a standard "Label" drill and will produce good length with mild backend reaction.
  • Place the center of gravity so as to balance 1/2" oz. positive and finger.
  • Rotate ball so that the pin (if applicable) is located at 1:30 in relationship to the center of gravity.
  • This layout will require no balance hole.

Layout 2 - Leverage Drilling

Storm Basic Drilling Layout 2
  • This drill pattern is known as a "leverage" drilling. This drilling provides medium length and maximum backend reaction.
  • In this layout we place both the pin and center of gravity 3-3/8" from the positive axis point.
  • Most often this drill pattern will require a balance hole to remove excess side weight.
  • Place the balance hole on the PAP and remove excess side weight down to 1/2 ounce positive.

Layout 3 - Axis Weight Drilling

Note: Be sure to select a ball with less than three ounces of top weight!
Storm Basic Drilling Layout 3
  • This drilling is referred to as "axis" weight. It provides early roll with a smooth, controllable backend.
  • Place the center of gravity on the player's positive axis point.
  • Rotate the ball so that the pin is located on the line between the PAP and finger holes.
  • Place the balance hole on the PAP and remove excess side weight to less than one ounce, This will ensure the balance of the ball is withing USBC specifications.

Pro Drilling Instructions

Note: For reaction adjustments, consult the Ball Surface Reaction Guide.
Be sure to check for excess side weight and finger/thumb weight, as a balance hole may be necessary for any of these layouts. If one is required, draw a line from the center of the grip through the CG and extend to the PAL. This will be the location of the balance hole.
