The Heirloom Billiard Table Glossary and Buyer Questions
Plain definitions of the terms you will meet in workshop specifications and showroom conversations, followed by answers to the broad questions every first-time buyer of a fine table asks.
- Apron
- The vertical panel that hangs beneath the rails around the perimeter of the table, concealing the slate edge and the top of the frame. Also called the blind, and often the most decorated part of the cabinet.
- Ball return
- An internal system of gullies or tracks beneath the slate that carries pocketed balls to a collection tray, usually at the foot of the table. Convenient for play but more complex to service than drop pockets.
- Beeswax seam
- The traditional method of filling the joints between slate sections, in which melted beeswax is poured into the seam and scraped flush once set. It leaves a surface the ball cannot feel and can be redone at any future re-leveling.
- Book-matched veneer
- Two consecutive slices of the same log opened like the pages of a book so their grain mirrors along a center line. Used on wide cabinet panels where a thick veneer over a stable core is more dimensionally reliable than a wide solid board.
- Cabinet
- The wooden frame structure beneath the slate, including the longitudinal beam, cross members, and leg mounts. The cabinet carries the full weight of the stone and determines whether the table stays flat over decades.
- Carom table
- A pocketless billiard table used for three-cushion and other carom games, typically with a heated slate and a different cushion profile from pocket tables. Distinct from a pool table despite sharing the broader name billiards.
- Cushion
- The strip of rubber, triangular in section, fixed along the inside of each rail so that balls rebound from it. Natural gum rubber holds its liveliness longest; hardened cushions are the usual cause of a dead-sounding rail.
- Cushion nose
- The topmost edge of the cushion that actually contacts the ball. The playing surface of a table is measured from nose to nose, which is why it is smaller than the nominal table size.
- Diamond sights
- The small inlaid markers, usually diamonds or dots of mother-of-pearl, metal, or contrasting wood, spaced along the rails. Players use them as reference points for kick and bank aiming systems, so accurate placement matters.
- Drop pocket
- A pocket in which balls fall into a leather or woven basket hanging beneath the rail rather than into a return system. The traditional pocket style on heirloom tables and easily replaced when worn.
- Feather strip
- A thin strip of wood pressed into a groove along the rail to trap and hold the cloth in place after the cushion is covered. It is removed and replaced whenever the rails are re-clothed.
- Foot spot and head spot
- The marked points on the long center line of the table where the balls are racked (foot spot) and from behind which the break is taken (head spot). They also fix the direction in which the cloth should be brushed.
- K-66 profile
- The standard cushion cross-section used on pocket billiard tables in the United States, defined by the dimensions of its triangular shape. Carom tables generally use the related K-55 profile. The letter code describes shape, not rubber quality.
- Kiln-dried lumber
- Hardwood that has been dried in a controlled chamber to a stable moisture content before being worked. Essential for a table, because wood that dries after assembly shrinks, checks, and pulls joints open.
- Leveling feet
- Threaded metal feet or plates at the base of each leg that allow the cabinet to be adjusted to true on an uneven floor. Fine leveling of the slate itself is then done with shims between stone and frame.
- Mechanic
- The traditional name for a billiard-table technician, the person who installs, levels, re-cloths, re-cushions, and moves slate tables. A good local mechanic is as valuable to an heirloom table as a good tuner is to a piano.
- Nap
- The raised, directional fiber surface of woolen billiard cloth. Nap should always be brushed from head to foot, and it is the reason a woolen cloth plays a little slower and more forgivingly than a worsted one.
- Playing surface
- The area of cloth between the cushion noses on which the game is actually played. A nine-foot table has a playing surface of roughly one hundred by fifty inches, well inside its overall footprint.
- Pocket shelf
- The depth of slate that extends from the mouth of the pocket to the point where the ball drops. A deeper shelf makes pockets more demanding, since balls that enter slowly along the rail can rattle out.
- Quartersawn
- A method of sawing a log so that the growth rings run roughly perpendicular to the face of each board. Quartersawn lumber is more stable and, in white oak, shows the distinctive ray fleck figure prized in fine cabinetwork.
- Rail
- The wooden member along each edge of the playing surface that carries the cushion, the cloth cap, and the sights. Rails are bolted to the slate from beneath and are removed as a unit for re-clothing.
- Rail bolts
- The machine bolts that pass through the slate and fasten the rails to it. Rails held by bolts into captured nuts or threaded inserts can be tightened indefinitely; rails held by wood screws alone cannot.
- Slate
- A fine-grained metamorphic rock that can be machined dead flat and does not warp with humidity, which is why every serious billiard table uses it as the bed. Thickness of one inch is the accepted standard in the heirloom class.
- Slate liner
- A wooden frame or backing bonded to the underside of each slate section. It stiffens the stone, gives the cloth staples something to grip, and helps the sections sit evenly on the cabinet.
- Snooker table
- A larger table, traditionally twelve feet, with smaller balls, narrower pockets with rounded cushion openings, and a napped cloth. It is a different game and a different instrument from an American pool table.
- Three-piece slate
- A slate bed made of three separate sections laid end to end and seamed on the frame. Preferred on large tables because each piece can be leveled independently and carried through a house without cracking.
- Woolen cloth
- Billiard cloth woven from carded wool fibers, with a raised nap. It is the traditional covering for home tables, feels soft, plays a little slower than worsted, and is forgiving of an imperfect stroke.
- Worsted cloth
- Billiard cloth woven from long, combed wool fibers with no nap. It plays faster and truer, resists pilling, and is the standard in tournament rooms; it typically costs more and shows chalk more readily.
Questions people ask
What actually makes a pool table an heirloom rather than just an expensive one?
An heirloom table is built to be serviced indefinitely and to improve with age: a solid kiln-dried hardwood cabinet, a one-inch three-piece slate bed, natural gum rubber cushions, and hardware that can be tightened or replaced decades later. Ornament and finish are secondary. Many expensive tables fail one of those tests, and some plain ones pass all of them.
How thick should the slate be on a premium home table?
One inch, in three pieces, is the accepted standard for a serious table and is what tournament specifications generally require. Thinner slate is sometimes used on smaller or convertible tables to control weight, and it is not automatically a problem on a seven-foot table, but it is a compromise you should be told about in the specification rather than discover later.
Which hardwood is best for a billiard table?
There is no single best species; there are species that suit different rooms and tastes. Hard maple is dense and structurally superb, walnut is warm and stable, cherry darkens beautifully over its first years, and mahogany and quartersawn white oak carry strong period associations. What matters more than species is that the wood is properly kiln-dried and joined with real joinery.
How big a room do I need for an eight-foot or nine-foot table?
Measure the playing surface and add about five feet on every side for a standard fifty-eight inch cue. That gives roughly thirteen and a half by seventeen feet for an eight-foot table and roughly fourteen by eighteen feet for a nine-foot table, with more always welcome. Also confirm the delivery path, the floor structure, and ceiling height for a light fixture.
Is worsted or woolen cloth the better choice for a home?
Worsted cloth plays faster and truer, resists pilling, and is what tournament rooms use, so it suits a dedicated player. Woolen cloth is softer, slower, more forgiving, and traditionally the home choice. Either is appropriate on an heirloom table; the decision comes down to how seriously the household plays and how willing it is to brush and cover the table.
Do I really need professional installation?
Yes. Installation is where the frame is leveled, the slate sections are set and leveled with a machinist level, the seams are filled, and the cloth is stretched evenly. Movers and handymen can usually get a table standing but rarely get it playing true, and slate cracks easily when mishandled. Many makers also tie their warranty to installation by an approved mechanic.
How often does a fine table need re-clothing and new cushions?
Cloth on a family table typically lasts several years, sooner under heavy play and much longer under light use. Cushions of natural gum rubber often last decades; a dull-sounding rail or a short rebound is the sign they are due. A re-level check whenever the cloth is changed is sensible, since wooden floors move with the seasons.
Can a convertible dining billiard table be a true heirloom?
It can, when it is built with the same cabinetwork, one-inch slate, and gum cushions as a conventional table and merely finished to dining height with a conversion top. Examine the slate thickness and frame with particular care, because some convertible tables are furniture first and billiard tables second, and confirm you have somewhere to store the top panels.
Are hand-carved bespoke tables worth the premium?
Only if you value the object as much as the game. Carving does nothing for play; the same slate and cushions sit beneath a plain table. A bespoke commission is justified for a collector, or for a room designed around the table, and should be approached like commissioning any fine furniture, with drawings, approvals, and a long lead time.
How should I care for the table week to week?
Brush the cloth after play, always from head to foot, with a soft brush. Keep the balls clean, cover the table when idle, and keep the room in the moderate humidity range that protects any fine furniture, away from radiators, fireplaces, and direct sun. Wipe wood with a barely damp cloth and follow the maker guidance on renewing an oil finish.
Can an heirloom table be moved to a new home?
Yes, but only by full disassembly. A mechanic removes the rails, lifts the slate sections individually, and dismantles the cabinet, then re-sets, re-levels, and usually re-cloths the table at the new address. A slate table should never be slid, tipped, or carried assembled, because the twisting load opens seams and can crack the stone.
What records should I keep with the table?
Keep the invoice, the specification sheet, any workshop drawings, the installer notes on shims and floor quirks, and a simple log of every re-cloth, cushion replacement, and re-level. That folder lets the next owner or generation service the table correctly and materially supports its value if it is ever sold.
