while third primary goniometer 95 is located perpendicular to goniometers 91 and 93 lower plate 131 is constructed from an aluminum sheet 133 adhered to a laminated sandwich 135 consisting of a pair of outer aluminum skins with either a balsa wood or aluminum honeycomb spacer therebetween this laminated sandwich adds significant structural stiffness to lower plate 131 lower plate 131 has a u like shape with an open cavity 137 for allowing free travel of the tilted laser optic head 51 bracket 81 is bolted upon driving bearing block 97 of third primary goniometer 95 such that manually actuated z axis slide 77 operably tilts side to side an upper plate 141 constructed the same as lower plate 131 is bolted upon driving bearing blocks 97 of first primary goniometer 91 and second slave goniometer 93 hence lower plate 131 tilts and rotates in concert with goniometers 91 and 93 upper plate 141 has a central key holed orifice 143 for receiving laser optic head 51 referring now to fig1 through 3 slide set 35 includes an automated z axis slide 161 an automated u axis slide 163 a manually actuated t axis slide 165 and their associated mounting bracketry a support bracket 167 is bolted onto an upper face of upper plate 141 furthermore a stationary segment 169 of t axis slide 165 is bolted onto an upper shelf of support bracket.
