Abstract
An apparatus and method are provided for precisely positioning a locksmith tool in the area of a dial ring of a combination lock of a safe. The apparatus includes a derrick that holds and supports the locksmith tool. An offset, annular base forms a part of the derrick and has an opening with an inner diameter substantailly corresponding to the diameter of the outer periphery of the dial ring. The base is placed over the dial ring and radially extending set screws in the base are tightened into engagement with the dial ring. In this manner, the derrick is securely attached to the safe. The apparatus also includes a mechanism for precisely controlling and adjustably positioning the tool relative to the safe. The method includes the steps of (1) identifying the type and model of lock on the safe; (2) selecting a dial ring attaching means corresponding to the lock; (3) connecting the selected dial ring attaching means to the mounting means; and (4) attaching said mounting means to the safe door by securing the dial ring attaching means to the dial ring.
