Lane oil patterns
Did you know that a 16lb bowling ball can hit the lane with a force of over 2000lb per square inch?
Just think of the amount of friction there would be between the ball and the lane. That is the main reason oil is placed on the lanes, to protect them from all the wear and tear that would be caused. This oil can be placed on the lanes in different ways, which are known as "oiling patterns".
Table explaining patterns on bowling lanes.
| Flat Oil |
Flat oil is simple, it is an equal amount of oil across the entire width of the lane. |
| Block |
A block pattern is very simple. It is where there is more oil in the middle of the lane, with less on the outside boards. This can also be known as a "wall", where a wall of friction is created on the outside boards. For a hook bowler this is usually a very high scoring pattern. The hook bowler will place their ball on the lane where there is oil, angling it out to the edge boards where the friction increases and allows the ball to "turn over" and hook into the pins (hopefully into the pocket). |
| Reverse Block |
A reverse block is exactly how it sounds, it is where there is more oil on the outside boards and less in the middle part of the lane. A reverse block is usually created by straight bowlers playing down the middle of the lane and "stripping" or "drying" out the oil. It is a very hard condition to play on and every hook bowler's nightmare. |
| Christmas tree |
The Christmas Tree condition is commonly thought to be one of the fairest possible competition conditions. The oil starts at each side of the lane and goes into a point further down the lane, creating a triangle resembling a Christmas tree. This condition caters for all styles. It allows the big hook bowler or cranker to move deep into the middle of the lane and swing the ball out to the edge of the lane where there will be more friction. At the same time, this condition allows a lesser hook bowler or stroker to play up the edge of the lane. |
Ball Tracks
After each delivery, you will notice that your ball will come back with a line of oil round it.
This is known as your ball track and can give you useful information as to what kind of bowler you are.
Table explaining ball tracks.
| Semi-Roller |
Notice how the track is just to the side of the fingers and thumb. This shows that the ball is tilted a little as it rolls down the lane and then impacts with the pins. This tilt creates mix as it sends the pins in a more horizontal direction. This style is used by strokers. |
| Flare |
Modern balls (since the mid-1990's) have introduced the concept of "dynamic imbalance" which means the ball moves off it's initial track and creates a new track with each rotation. This is called flare, and it means that more of the clean surface of the ball is in contact with the lane, potentially meaning more hook. |
| Full-Roller |
This style was successful in the past, but is not that common in today's game, due to modern lanes and equipment. The track of the ball runs between the fingers and the thumb. If you measure the length of a full-rollers track, you will find it is equal or very close to the circumference of the ball (27"). |
| Spinner |
This is the sort of track you would find on a helicopter bowler's ball. The spinners release creates more axis-tilt, which reduces the size of the track. The end result is a ball that travels further down the lane with little lateral movement and deflects as it hits the pins. This style makes it easier to score on almost any condition. |
