A full set will have been cut from the same log – they will be identical in weight and balance and any variation in weight due to natural shrinkage of the lignum will be uniform.First quality new bowls are expensive, but a good second-hand set can be obtained at a reasonable price.The set should be a “matched” set – check by looking for the set number which will be stamped on each bowl.A composition bowl is heavier than a lignum bowl.The bowl must not be too large for your hand.Lignum vitae bowls are generally more responsive to bias than composition bowls, and are less affected by heavy greens.īowls are made, and should be bought, in sets of four – four bowls is the maximum number any one player in any one game requires. Composition bowls are heavier, size for size, than bowls of lignum vitae, so the player with a small hand can use a bowl made of composition of diameter 1/8th inch less than a lignum vitae bowl of equivalent weight.Ĭomposition bowls are unaffected by temperature changes lignum vitae bowls, having lost their polish, lose weight on exposure to the sun. The choice of bowl will therefore be influenced by the size of the player’s hand and the particular grip adopted when playing. It is an advantage to use as heavy a bowl as possible without overloading the grip. Some bowls are made of a very hard wood called lignum vitae such bowls must have a circumference not greater than 16 1/2 inches and must not weigh more than 3 1/2 lbs.

In all subsequent ends the back edge of the mat shall be placed not less than four feet from the rear ditch and the front edge not less than 25 metres from the front ditch and on the centre line of the rink. The MatĪt the beginning of the first end of the mat is placed lengthwise on the centre line of the rink, the back edge to be four feet from the ditch. The bank shall be not not less than 23cm above the level of the green, preferably upright or alternatively at an angle of not more than 35 degrees from the perpendicular.įor domestic play the green may be divided into rinks not less than 4.2 metres nor more than 5.7 metres wide. The green must be level and surrounded by a ditch and bank. These pegs and thread define the boundary of the rink. These corner pegs shall be connected with green thread drawn tightly along the surface of the green with sufficient loose thread to reach the corresponding pegs on the face of the bank. The four corners of the rinks shall be marked by pegs of wood, painted white and fixed to the face of the bank and flush therewith.
