Each leveling screw 82 may include a slot 86 at one end 88 that can be used to rotate the leveling screw 82 in either a clockwise or counter-clockwise direction. Such rotation of the leveling screw 82 via the slot 86 causes an adjustment in the height of the opposite end 90 of ihe leveling screw 82, which suppons the bottom surface 92 of the router insen plate 70. By adjusting the height of the leveling screws 82, the top surface 94 of the router insert plate 70 can be precisely leveled and made flush with the top surface 34 of the router top 14 to prevent the existence of any gaps that can impede smooth transitioning of the workpiece across the work surface. In some appllcations, the use of adjustable leveling screws 82 may also pennit router insert plates of varying thickness to be mounted to the router top 14, if desired.
Figure 6 is a side cross-sectional showing the connection of the miter track 48 to the router top 14. As shown in Figure 6, the miter track 48 may include a main T-shaped slot 96 adapted to receive a miter gauge, and a secondary T-shaped slot 98 adapted to receive various other accessories sach as a feather board, fence stop, table stop, and/or starting pin. The main slot 96 may be dimensioned slightly larger than the secondary slot 98, having a dimension of about 3/8 inches by 3/4 inches. The dimensions of the main slot 96 and/or the secondary slot 98 may vary, however, for use with other tools and accessories, as desired.
_g-A bendable gib 100 located along the front wall of the miter track 48 can be configured to displace slightly to facilitate insertion and/or removal of the miter gauge within the main slot 96. Bending of the gib 100 may be accomplished, for example, by squeezing the gib 100 against the frQnt wall of the miter track 48 with a pair of channel locks. A set screw 102 disposed through the front wall of the miter track 48 can be utilized to engage the gib 100 against the miter gauge once inserted within the main slot 96. A number of mounting bolts 104 can be utilized to secure the miter track 48 to the channel 46 of the router top 14, if dzsired_ Figure 7 is an assembly view showing the attachment of the router top 14 io thC
adjacent iable saw top 16 of Figure 1. As shown in Figure 7, each end 28,30 of the router top 14 may include a number of mounting bolts 106 that can be tlueadably engaged within a number of openings disposed within the adjacent end 108 of the saw top 16.
Each mounting bolt 106 can be received within three oversized holes 110 formed through each end 28,30 of the router top 14, allowing for connection to adjacent members employing a three-hole mounting pattern_ A second set of four holes 112 formed through each end 28,30 of the r~outer top 14 can be further provided for attachment to adjacent members employing a four-hole mounting pattem, if desired. In either the three or four-hole mounting configurations, a nuanber of heavy rectangular washers 114 can be provided for use with one or more of the openings 110,112 to permit the moun.ting bolts 106 to be attached to adjacent members having holes that are offset slightly, if necessary.
Figure 8 is a perspective view showing the connection of a rip fence 116 to the worktable 10 of fiigure 1. As shown in Figure 8, the rip fence 116 can be attached to the router top 14 using the fence mounting slots 44, which allow the rip fence 116 to be adjusted relative to the opening 32. Attachment of the rip fence 116 to the router top 14 may be accomplished, for exampie, using a set of T-knobs each threadably connected to a corresponding bolt located underneath the router top 14. A built-in vacuum dust pon 118 connected to the rear side of the rip fence 116 can be coupled to a vacuum hose (nor shown) for connection to a dust collection system. Other features such as a dual position bit guard, adjustably sliding sub fences, front and back T-slots, and built-in jointing settings may also be provided on the rip fence 116, if desired.
As can be further seen in Figure 8, the router top 14 can be further configured for use as a second (i.e. right) extension of the worktable 10, having a second extension wing assembly 42 equipped with an L-shaped side rail 50, mounting bracket 52 (hidden), and fence guide 54, similar to that described above with respect to the first wing assembly 40 of Figure 1. In the illustrative embodiment of Figure 8, however, the second extension wing assernbly 42 extends beyond the end 30 of the router top 14 a short distance such that the fence guide 54 spans the entire length of the router top side 26.
1S While the iilustrative embodiment of Figure 1 shows the attachment of the router top 14 immediately adjacent to a table saw top 16, it should be understood that the router top 14 could be utilized in any number of desired configurations, either alone or in conjunction with one or more additional worktable top members such as a table saw, band saw, jointer, and/or power sander. In one such alternative worktable 120 depicted in Figure 9, for example, the illustrative router top 14 may be mounted to a support scructure 122 including a blank top 124, a table saw top 126, and an end cap 128. The blank top 124 may be interposed between the router top 14 and the table saw top 126, thus providing a greater amount of table surface between the saw blade 130 and the router top 14. The end cap 128, in turn, may be located adjacent the side of the table saw top 126 located opposite the blank top 124, thus providing a greater amount of table surface to the left of the saw blade 130.
Figure 10 is a perspective view of an illustrative worktable 132 in accordance with another exemplary embodiment of the present invention, wherein the worktable 132 comprises a stand-alone router table. As stiown in Figure 10, the router top 14 can be configured to mount to a cabinet 134, allowing the user to store various tools and supplies while also conserving space. An opening 136 disposed within the interior of the cabinet 134 can be adapted to receive the router (not shown) located below the surface of the router top 14. In certain embodiments, and as funher depicted in Figure 10, a cast iron end cap 138 cart be connected to the router top 14 and cabinet 134 to increase the amount of table surface available and to provide a more finished look, if desired.
Figure 11 is a perspective view of an illustrative worktable 140 in accordance with another exemplary embodiment of the present invention, wherein the worktable 140 includes two router tops 14a,14b.
