After re-insulating or repairing, the job looks more complete and satisfactory to your customer if the battery is furnished with a new set of connectors. Use your scrap lead and make new connectors for each job. It pays.
AMBU SCREW MOULD
The lead capped screws of the taper type terminal are another of the frequently replaced parts. Although the round knurled head type is no longer installed, a great many men still use pliers on the square head terminal screws with the result that the soft square lead head is damaged to such an extent that a tight connection cannot be made.
The AMBU-Washburn Screw Mould, Figure [13], will cast standard square edged heads on four screws in one operation, two 5⁄16-inch and two ⅜-inch. It has screw adjustments in the base, making it adaptable to any length screw.

As the finished screws are removable from the top, the position of the mould is not changed while in use and castings can be made at the rate of 12 screws a minute.
