To release the clamping force, the user lifts the release member 150, which reduces the frictional engagement between the locking member 146 and the rod 102.
    Referring to Fig. 2, the illustrated drill guide assembly 22 includes a guide block 162 which is received within the guide support 38. In the illustrated embodiment, the guide block 162 can slide the along an adjustment axis 166 which is substantially perpendicular to the clamping axis 90 and to the upper surface 30 of the main body 26. The guide block 162 comprises a flat front surface or a second clamping surface 170 which is substantially parallel to the first clamping surface 110 on the clamping arm 94 so that a workpiece can be clamped between the first and second clamping surfaces 110, 170. A rear surface 174 of the guide block 162 is positioned adjacent to the the rear wall 46 of the guide support 38. In the illustrated embodiment, the openings 178 extend through the rear surface 174 (Fig. 4) and are generally aligned with the elongate openings 70 in the housing. rear wall 46 of the guide support 38 (Figure 2) to facilitate the removal of dust and debris generated during a drilling operation. The guide block 162 further includes first and second arms 182 (Fig. 4). Each of the arms 182 includes a rack gear portion 186 which is part of the adjustment assembly 300 described in more detail below.
    Referring to Fig. 5, the guide block 162 further includes a generally rectangular recess 190 extending inward from the front surface 170 to the rear surface 174. An insert 194 is received in the recess 190. insert 194 is located in the area where a drill bit would enter the workpiece while drilling a blind hole. In some cases, the guide block 162 may be plastic and the insert 194 may be metal. Thus, the insert 194 provides greater durability in the piercing area while allowing the remainder of the guide block 162 to be made of a lighter and / or less expensive material. In some embodiments, the insert 194 may be removable and replaceable. In other embodiments, the insert 194 may be permanently attached in the receptacle 190. The illustrated drill guide assembly 162 further includes first and second sockets 200, 204 received in the first and second bores. angular 208, 212 formed in the guide block 162 (Figure 4 or 5). The first bushing 200 includes a first cylindrical passage 216 for guiding a drill bit 220, and the second bushing 204 includes a second cylindrical passage 224 for guiding the drill bit 220 (Figure 5). In the illustrated embodiment, the first bushing 200 has an oval shape and is reversible relative to the first angular bore 208 to provide two different positions for the first cylindrical passage 216. Thus, the first bushing 200 is movable between a first position ( illustrated in Figs. 4 and 5) to provide a first predetermined spacing between the first and second cylindrical passageways 216, 224 and a second position (not shown) to provide a second predetermined different spacing between the first and second cylindrical passageways 216, 224. In some embodiments, the first spacing may be between about 1 inch and about 2 inches, and the second spacing may be between about 1.5 inches and about 2.5 inches. In the illustrated embodiment, a hand-tightening screw 228 is provided to secure the first bushing 200 in the first position or in the second position.
    The guide block 162, the insert 194 and the sockets 200, 204 collectively define the first and second guide channels of the drill guide assembly which extend at an oblique angle along the parallel and spaced axes 232, 236. The inclined guide channels are configured to guide the bit 220 to an appropriate angle to form a blind hole in a nip between the first and second clamping surfaces 110, 170 (Fig. 2). In the illustrated embodiment, the drill guide assembly 22 includes two guide channels. In other embodiments, the drill guide assembly 22 may comprise a single guide channel or more than two guide channels.
    Referring to FIG. 6, the blind hole template 10 further includes an adjusting mechanism 300 which connects the clamp assembly 18 and the drill guide assembly 22 so that the movement of the carriage 86 and the clamp arm 94 for clamping a workpiece of a particular thickness automatically positions the drill guide assembly 22 in a predetermined position corresponding to that thickness. The adjusting mechanism 300 includes first and second compound gears 304, 308 rotatably coupled to the base 14. Each of the compound gears 304, 308 includes a first pinion 312 or a toothed portion having a first diameter and a second pinion 316 or a toothed portion having a second diameter greater than the first diameter. In the illustrated embodiment, the first pinions 312 are meshed with the rack portions 118 of the coupled arms 114 to the carriage 86. The second pinions 316 mesh with the rack portions 186 of the arms of the guide block 182. Accordingly, the compound gears 304, 308 convert the horizontal movement of the carriage 86 and the clamp arm 94 to a first vertically moving speed of the drill guide assembly 22 at a second speed. As the second diameter is larger than the first diameter, the second speed is smaller than the first speed. The first and second diameters are dimensioned to correlate the thickness of the workpiece with the appropriate height of the piercing guide assembly 22.
    In addition to facilitating the efficient and convenient adjustment of the drill guide assembly 22, the illustrated embodiment of the adjustment mechanism 300 allows the blind hole template 10 to have a relatively thin base 14. Referring to Fig. 1, the base 14 defines a thickness or height H measured between the upper and lower surfaces 30, 34. In the illustrated embodiment, the height H is about 1.5 inches; however, in other embodiments, the height H may vary. In addition to being relatively compact, the 1.5 inch height H allows the top surface 30 of the base 14 to align with the top surface of the adjacent standard material 1.5 inches thick. Therefore, commonly used materials can be used to effectively extend the top surface of the base 14, which can provide increased stability when positioning large pieces on the base 14 of the blind hole template 10.
    In operation, with reference to FIGS. 7 and 8, when the user squeezes a workpiece of particular thickness with the clamping assembly 18, the adjusting mechanism 300 automatically adjusts the height of the piercing guide assembly 22 to a level appropriate for the thickness of the room. The user can insert the bit 220 through the cylindrical passages 216, 224 (FIG. 5) and drill blind holes in the part along the axes 232, 236.
