Claim:
1. An alignment device to assist in drilling or reaming an opening in a structure, the device comprising: a base element, the base element having at least one first fixation element to allow fixation of the base element relative to the structure; a positioning element coupled to the base element, the positioning element comprising a slider with a flat surface configured to engage a corresponding flat surface of the base element, wherein a position of the positioning element relative to the base element is selectively adjustable with at least two translational degrees of freedom relative to the base element to allow precise positioning for a drilling or reaming tool with respect to a drilling or reaming site on the structure; an alignment element mounted to the positioning element, wherein an angle of the alignment element is selectively adjustable with at least two rotational degrees of freedom relative to the base element to allow precise alignment for the drilling or reaming tool with respect to the drilling or reaming site on the structure; at least one second fixation element being pneumatically actuable and configured to selectively fix the positioning element relative to the base element by forcing respective parts of the flat surfaces of the slider and the base element together to achieve frictional engagement and thereby restrict movement of the positioning element relative to the base element; and at least one third fixation element to allow fixation of the alignment element relative to the positioning element to fix the angle of the alignment element relative to the structure.
