Claim 12:
13. 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; the tower interface moveably supporting the tower; the tower interface further 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;
at least one first cylinder connected between the tower and the platform for causing the movement of the tower in the plane of the longitudinal axis;
a pivoting tilt joint; the pivoting tilt joint moveably joining the frame of the tower interface assembly to the platform;
a clevis; the clevis connected to the frame of the tower interface assembly;
at least one slide tube connected between the platform and the frame; and,
at least one pinning cylinder connected to the at least one slide tube for selectively locking the at least one slide tube in a predetermined position;
the tower interface assembly 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;
whereby the titled drill string can perform angled drilling in either position.
