Claim 7:
8. A drilling machine for angled drilling where the drilling machine has a platform having a longitudinal axis, and a transverse axis; the drilling machine comprising:
a tower for holding a drill string;
a tower interface assembly connected to the platform and supporting the tower;
wherein the tower interface assembly is selectively moveable to tilt the tower in either a plane parallel with the longitudinal axis of the platform, or to tilt the tower in a plane parallel with the transverse axis of the platform; the tower interface assembly comprising:
a frame; the frame moveably connected to the platform; a pivot shaft; the pivot shaft disposed to allow the tower to tilt in the plane of the longitudinal axis about the pivot shaft;
a pivoting tilt joint; the pivoting tilt joint moveably joining the frame of the tower interface assembly to the platform for tilt in the plane of the traverse axis of the transverse axis;
at least one clevis; the at least one clevis connected to the frame of the tower interface assembly;
at least one first cylinder connected between the clevis and the platform so as to cause the tower interface assembly frame to tilt about the pivoting tilt joint in the plane of the transverse axis as the first cylinder extends;
a first pinning cylinder disposed on the tower interface assembly frame and having at least one pinning pin; and,
at least one first slide tube connected between the platform and the frame; the at least one first slide tube having holes for receiving the at least one pinning pin of the at least one first pinning cylinder, so as to lock the tower into a selected tilt in the plane of the transverse axis;

whereby the tilted drill string can perform angled drilling in either position.
