R
RACK
The complete set of pins when set on the pindeck; aka "full rack".
RADIUS OF GYRATION (RG)
Identifies how fast a ball begins to rotate once it leaves the bowler's hand.
RAIL
Same as picket fence.
RAILROAD
A wide split on which both pins are on the same line; e.g., the 7-10, 8-10, 7-9, or 4-6.
RANGE FINDERS
Markers in the lane that help the bowler determine the target line. There are two sets of such markers: ten dots located seven feet past the foul line and seven arrows arranged in a triangle beginning 16 feet beyond the foul line.
RANGE FINDERS (ALLEY SIGHTS)
5 targets, each 1X7 inch, 6½ inches apart; forming a 2 foot long arrowhead centered 20 feet beyond the foul-line installed in many candlepin centers.
RAP
When a single pin remains standing after an apparent good hit. See also "tap". Same as burner.
REACTIVE RESIN
A polymer that is a cousin to traditional urethane; used as the coverstock on most modern balls; it is generally a surface that grabs the lane sooner, resulting in more and earlier hook than other coverstock surfaces. They can feel "tacky/sticky" when warm. They tend to "react" much more to differing lane surfaces, hooking more on drier lanes and skidding more in oil.
READING THE LANE
Experimentation, usually during practice, to determine the characteristics of a lane. Some lanes are faster than others, some will allow a bigger hook while others will hold the ball back, etc.
READING THE LANES
The process of discovering how your ball reacts on different portions of the lane surface; hopefully, finding the best area to use to maximize strike potential.
REFINISH/RESURFACE
To sand and/or polish a ball that is heavily tracked in an attempt to restore the out-of-box finish.
RELAXED FINGERTIP
A grip that is more than a semi-fingertip but not as far stretched as a full fingertip grip.
RELEASE
The point at which the ball is put onto the lane; also, the hand action that takes place at that point.
RE-RACK
Resetting the pins to a new full rack due to a perceived mis-spotting of one or more pins.
RERACK OR RESET
A call by a bowler asking that the pins be lifted from the alley and put back properly, because they're off spot.
RETURN
A track that brings balls back from the pit.
REV LEVERAGE
A drilling with the pin 4-1/2" and the CG 3-3/8" from the bowler's PAP. The CG is placed down in the thumb and positive quadrant of the ball and the extra hole is located 6 3/4" from the pin on a line through the CG. The ball must have a 3+ inch pin out to start.
REVERSE
A severe backup.
REVERSE BLOCK
For most people, a very difficult lane condition in which the boards closer to the gutter are heavily oiled, while those in the center are dry. The difficulty is that if the ball is thrown in the center, it tends to hook too much and ride high; if you adjust and throw the ball more to the right, the ball will hit the oil and not get back to the pocket. See also "block".
REVERSE PITCH
Angling of the thumbhole backward so the tip of the thumb is extended away from the palm. It is used to help the thumb exit the hole sooner; although very common and generally desirable, too much can cause the ball to fall off the hand early .. i.e., dropping the ball. See "back pitch".
REVS/REVOLUTIONS
The number of times the ball rolls over its circumference from when it is released until it contacts the pins; as a rule, more is better. However, it is also commonly referred to as the number of times the ball rotates on its axis from release to contact with the pins. Here it is less clear whether more is helpful, as it would depend a great deal on the location and diameter of the ball track.
RHB
Right handed bowler.
RINGING 10 PIN
When the 10 pin stands after a particularly hard hitting shot; see "soft ten" also.
RINGING TEN-BURNER
An apparently good hit on the pocket that fails to knock the 10-pin down.
ROCK
The bowling ball.
ROCKET
A ball thrown with extra speed; see also "bb" and "bullet".
RODE THE OIL LINE
A method of lane play where there is an oil line/crown into the pocket and the player keeps the ball on the oil line into the pocket; can result it high scores. See also "bumped the oil line".
ROLL OUT
A ball that loses its side rotation before hitting the pins; the hook action stops at that point and the ball straightens out; generally undesirable; see also "hookout" and "hook and set".
ROTATION
The spin given to the ball that creates both the break and action.
ROTATIONAL ENERGY
The energy created by the release and rotation of the hand up, around, through, and/or over the ball. This is the rotation of the ball.
RUN/RUNNING LANE
A lane that hooks excessively. "My ball hit the lanes and ran left!"
RUNWAY
Normally the approach area behind the foul line; also the name given to the areas to the side of the house end lanes where the staff can walk (run!) to the machines for service.
