Abstract

Disclosed is a bore measurement unit having an elongate main body with first and second ends. A first adjustment mechanism is disposed near the first end and a second adjustment mechanism is disposed near said second end. The adjustment mechanisms expand or contract, through triangulating arms, to relative diameters, such that when the unit is inserted into a hollow bore it may be centered therein. A measuring portion of the unit measures the internal diameter of the bore. The measuring unit includes at least one sensor and preferably takes more than three readings at each distance of insertion to formulate a best fit circle of the inner bore diameter.
