    摘要: Weight spacer apparatus is disclosed which comprises a carrier which is tubular in shape and a spacer tube which is also tubular in shape for insertion into the carrier. The weight spacer apparatus according to the present invention further comprises a plurality of weight bars which may be inserted into the spacer tube after the spacer tube is inserted into the carrier and which are also removable from the spacer tube. In one embodiment, a weight tray is inserted into the spacer tube for receiving the weight bars, and the weight tray may be fabricated from half-round tubing with a welded plate to cover the diametric opening. In another embodiment, a center plate is attached inside the spacer tube along the length of the spacer tube to divide the spacer tube into first and second compartments. The first compartment comprises a weight tray for receiving the plurality of weight bars, and the portion of the spacer tube opposite the first compartment has openings formed in it to receive shaped charges.
