=Splicing on the Detonator.= (_Plates I and II._)—The detonator should now be spliced to the spar leading-wires. In splicing on the detonator, so arrange the length of wire that the spherical rubber packing can be placed on the leading-wires five inches from the bottom of the detonator-case, the splices being between the detonator and the packing. Remove the water-cap from the screw-cover of the case. Strip the braiding and rubber tape from the leading-wires for at least six inches from their ends and put on a neat whipping, which shall be outside the packing. Reeve the ends of the leading-wires through the water-cap and rubber packing. Remove so much of the insulation as may be necessary, for making the splice, from the leading-wires and from the legs of the detonator; brighten the wires and place the insulation of the detonator-legs alongside that of the leading-wires, with the ends of the insulation flush, and expend the bare detonator-legs in turns at right angles around the leading-wires. Turn the ends of the leading-wires back over the splices, and trim off the ends. _One splice should be one-half inch from the detonator and the other one inch from the packing._ Insulate from metallic contact the splice nearest the packing with twine and pass several turns about the wires until the detonator is reached, where the end of the twine is secured. A strip of okonite tape can be used, taking care that the insulation is not too bulky. (See sample splice in supply-box). =Fuzing the Service Torpedo.= (_Plate I._)—Having lined the holes of the dry blocks with the rectifier, to be found in the supply-box, enter the detonator through the hole in the cover and push it in until the packing is seated; screw up the water-cap hand-tight. Provide the spindle, to be found in Box 53, and secure it to the torpedo-case. =Shipping the Secondary Spar.= (_Ship‘s._)—Enter the end of the secondary spar in the loop of the outer band, and push in until the key-way is abreast the slot in the loop of the inner band; then put in the key and stop it in. =Shipping the Service Torpedo.= (_Ship‘s._)—Insert the stem of the spindle in the outer end of the secondary spar and push it home as far as the shoulder. Put in the torpedo-pin and stop it in. To prevent the strain of towing from starting the splice, turn a cuckold‘s-neck in the spar leading-wires, and lash it to the secondary spar or to the spindle, clear of the torpedo-case. The spar leading-wires should then be led in along the ship‘s spar, abaft the topping lift, and stopped to it at intervals of about four feet.
