Asymmetric Drilling Information

On Asymmetrical cores the CG's only influence is to determine the size of the extra hole, if needed. That is why we use the Pin and the CAP only for layouts.

Reference Points:
Determining The Proper Pin Location
The Pin Location Controls the Length of the Ball Reaction.
Use Higher Pins For Length, Lower For Earlier Roll.
- The Control Pin Location allows a very Early Smooth Reaction.
(2" from bowler's PAP) - The Power Pin Location allows the ball to use its full flare potential - strongest midlane reaction.
(3 1/2" from bowler's PAP) - The Delay Pin Location stores the balls energy and add length with an angular backend.
(5" from bowler's PAP)
Direct Cap
The Direct Cap location decreases the entry angle.
(5 to 6" from the bowler's PAP usually below the thumb hole)
Recomendations
- Adds length and helps control dry backends
- Allows bowler to stand closer to the "dry"
- Freshly oiled Lanes and extremely "wet/dry" conditions
Power Cap
The Power Cap location maximizes the entry angle.
(3 to 4" from the bowler's PAP)
Recommendations
- Creates length with an angular backend
- Good for heavy oil lines with carrydown
- Fresh heavy oil with clean backends
Control Cap
The Control Cap location produces medium entry angle.
(directly below bowler's PAP)
Recommendations
- Allows for smooth continuous backend reaction
- Good for players with high ball speeds on heavy oiled patterns
- High Ball speeds and extremely dry backends
Symmetrical Drilling Information
Drilling 1
Locate the mass bias by drawing a line from the pin through the CG.
Find the location 6-3/4 from the pin alogn this line and mark it with an 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 MD 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.
Drilling 2
Locate the mass bias and mark it with an MB.
Place the major pin 4-1/4" from the player's PAP and locate the mass bias (MB) alogn the player's perpendicular axis line (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 meduim length and heavy midlane roll.
Usually works well on medium to heavy oil, especially longer oil patterns.
Drilling 3
Locate the mas 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 players ball track and PAL
Place the extra hole, if necessary, on the player's PAP, removing excess side weight to less than an ounce.
This is a High Flare layout and should only be used by low rev players seeking maximum ball reaction.
This layout is ideal for long/or heavy oil conditions for when you need the ball to break into a hook earlier than your other equipment.
Drilling 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 alogn the line located between the PAP and the player's finger holes.
Place the mass bias in the player's track.
Check side weight tos ee if an extra hole is necessary. If so, place the hole on the PAP.
This layout will produce heavy roll with a controlable 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.
Adjusting the Ball Surface
The ball reaction has been determined with the drill pattern. Now its time to adjust the surface of the ball to accommodate the oil volume.
-
Polish for Dryer Conditions
- 1000 grit or Higher Polish
-
Lightly sand for Medium Conditions
- 1000 grit Wet Sand, no polish, gray or green scuff pad
-
Heavy sand for heavier Oil
- 400 Grit Wet Sand, no polish, burgundy or green scuff pad
Drilling Extra Holes
- Size:
- Bigger holes, (Larger than 7/8), produce earlier roll and a stronger reaction while smaller holes have a much lesser effect on the ball reactions
- Location:
- Holes located inside the bowlers PAP (towards the grip) tend to smooth out ball reaction, while holes on the bowlers PAP create a strong mid-lane roll and holes past the PAP help create more flare and a stronger overall reaction. BE CAREFUL on hole location for high rev players or high differential equipment (0.050 and higher), it is recommended that the extra hole NOT go past the players PAP or the ball may roll over the extra hole. It is also recommended that the extra holes no be located more than 2" in any directions from the bowler's PAP.
