Abstract: An instrument for verifying the taper angle of a tapered bore comprising a handle portion to which a tapered probe is fixed. The tapered probe is formed so as to have a proper diametral relationship throughout its length with the tapered bore to be verified and has a plurality of radial jets therein, each corresponding to a different bore position. Coaxial passages are formed in the handle portion and the probe and a connecting rod is movable by an operator in an axial direction therein. Air is passed through an axial bore in the connecting rod for delivery to a piston at the opposite end thereof through which it is radially expelled through one of the probe radial jets. The connecting rod may be moved to predetermined positions, each corresponding to one radial jet, so that the piston may be properly aligned therewith. As the air passes through the probe radial jets, it is directed against the surface of the bore, creating a back pressure in the air system. Proper diametral sizing of the respective jets will cause equal back pressure readings to be generated when air is selectively passed through each of the radial jets, if the bore is properly tapered. If the bore is not properly tapered, the back pressure readings will vary between different radial passages.
