Table Bed height: The table bed playing surface, when measured from the bottom of the table leg, will be 29 1/4 minimum to 30 1/4 maximum.
Pocket Openings and Measurements:
Pocket billiard tables: pocket
openings are measured at two points - the first being measured between
opposing cushion noses where the direction changes into the pocket (tip
to tip). This is called the mouth. The second point of measurement
is at the narrowest point at the back of the facing. This is called the
throat.
Corner Pocket:
Mouth...................................................4 7/8" minimum
to 5 1/8" maximum
Throat...................................................4" minimum
to 4 1/4" maximum
Side Pocket:
Mouth..................................................5 3/8" minimum
to 5 5/8" maximum
Throat..................................................4 3/8" minimum
to 4 7/8" maximum
Vertical Pocket Angle 12 +,or - 1 degree
Shelf: The shelf is measured from the center of the imaginary line that goes from one side of the mouth to the other where the nose of the cushion changes direction to the center of the vertical cut of the slate pocket radius.
Corner Pocket........................................1
5/8" minimum to 1 7/8" maximum Side Pocket............................................0" minimum
to 3/8" maximum
Drop Point Slate Radius: The pocket radius measured from the vertical cut of the slate to the playing surface.
Drop Point Slate Radius...................1/8" r.
Minimum to 1/4" r. Maximum
Playing Bed:
The playing surface must be capable, either by its own
strength or a combination of its strength and that of the table baseframe,
of maintaining an overall flatness within a tolerance of .020" lengthwise
and .010" across the width. Further, this surface should have an additional
deflection not to exceed .030" when loaded with a concentrated static
force of 200 pounds at its center. If more than one slab is employed, the
slab joints must be in the same plane within .005" after leveling
and shimming. The bed must be covered with a fabric, the major portion
of which is made of wool, with proper tension to avoid unwanted ball roll-off.
Commercial tables must have a 1" - 3 piece set of slate with a wooden
frame minimum 3/4" attached to slate. All playing surfaces must be
secured to base frame with screws or bolts.
Cushion:
Rubber cushions should be triangular in shape and molded
with the conventional K-66 profile with a base of 1 3/16" and a nose
height of 1", with control fabric molded to the top and base area
of the cushion. On carom billiard tables, the triangular k-55 profile cushion
is to be maintained, with the control fabric on the underside of the cushion
to effect a slower rebound action. On snooker tables, the triangular k66
profile or L-shaped snooker cushion is to be used. The balance of the rail
section to which the rubber cushion is glued should be of hardwood construction
and attached to the slate bed with a minimum of three (3) heavy duty, threaded
rail bolts per rail.
