Abstract:
1. A method for preparing a block for containing a receptacle assembly having a passageway having a second longitudinal axis, a first portion of the passageway having an outer surface having a first shape generally corresponding to a shape of an outer surface of a body formed by the intersection of a first cylinder with a second cylinder, the first cylinder having a third longitudinal axis, the second cylinder having a fourth longitudinal axis, the third longitudinal axis being coaxial with the second longitudinal axis of the passageway, the fourth longitudinal axis being generally parallel to and spaced a second distance from the third longitudinal axis, a second portion of the passageway having a generally circular cross sectional shape, the block having a first side and a second side opposed to and spaced a first distance from the first side, the first side having a first exterior surface and a first interior surface, the second side having a second exterior surface and a second interior surface, a cavity extending from the first interior surface to the second interior surface, the method comprising the steps of: drilling with a first-step corer of a three-step coring drill a pilot bore through the first side of the block, the pilot bore having a sixth longitudinal axis corresponding to the second longitudinal axis of the passageway; extending the first-step corer through the pilot bore to the interior surface of the second side of the block; drilling with the first-step corer a second cavity opening through the second side of the block; extending the first-step corer through the second cavity opening; drilling with a second-step corer of the three-step coring drill, the second corer having a diameter larger than the first corer, a first circular opening through the first side of the block; extending the second-step corer through the first circular opening; drilling with a third-step counter-borer of the three-step coring drill a first counter bore in the first side of the block; withdrawing the three-step coring drill from the block; removing the first-step corer from the three-step coring drill; drilling with the second-step corer a second circular opening through the first side of the block, the second circular opening having a seventh longitudinal axis corresponding to the fourth longitudinal axis; extending the second-step corer through the second circular opening; drilling with the third-step counter-borer a second counter bore in the first side of the block; and withdrawing the three-step core drill from the block.
