Additionally, each of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 and the fourth set of mortises 20 including a reference mortise 42. The reference mortise 42 of the first set of mortises 14 is oriented flush with an intersection between the first side 34 and the fourth side 40 of the outer surface 32. The reference mortise 42 of the second set of mortises 16 is offset 1/32 inch from an intersection between the second side 36 and the first side 34. The reference mortise 42 of the third set of mortises 18 is offset 1/16 inch from an intersection between the third side 38 and the second side 36. Finally, the reference mortise 42 of the fourth set of mortises 20 is offset 3/32 inch from an intersection between the third side 38 and the fourth side 40.
Each of the first set of mortises 14 is spaced apart ⅛ inch from each other, and each of the second set of mortises 16 is spaced apart ⅛ inch from each other. Each of the third set of mortises 18 is spaced apart ⅛ inch from each other, and each of the fourth set of mortises 20 is spaced apart ⅛ from each other. The block 12 has a pair of first holes 44 each extending through the first side 34 and the third side 38. The block 12 has a pair of second holes 46 each extending through the second side 36 and the fourth side 40. Additionally, each of the second holes 46 interests a respective one of the first holes 44.
A jig panel 48 is provided that has a plurality of jig mortises 50 recessed therein. The jig panel 48 is positionable against the edge 26 of the door 24 having the jig mortises 50 engaging respective ones of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20 in the block 12. In this way the jig panel 48 is retained at a selected location on the edge of the door 24. The jig panel 48 has a guide hole 52 therein thereby facilitating the guide hole 52 to be aligned with a preferred location to cut a hinge recess 54 in the edge 26 of the door 24. In this way the block 12 and the jig panel 48 facilitate the hinge recess 54 to be precisely located on the edge of the door 24.
The jig panel 48 has a bottom surface 56, a top surface 58 and a perimeter edge 60 extending therebetween, and the perimeter edge 60 has a front side 62, a back side 64, a first lateral side 66 and a second lateral side 68. The plurality of jig mortises 50 is recessed into the bottom surface 56 of the jig panel 48 and each of the jig mortises 50 extends between the first lateral side 66 and the second lateral side 68. Moreover, the jig mortises 50 are spaced apart from each other and are distributed between the front side 62 and the back side 64. Each of the jig mortises 50 is spaced ⅛ inch apart from each other thereby facilitating each of the jig mortises 50 to engage either the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20.
The guide hole 52 extends through the top surface 58 and the bottom surface 56 of the jig panel 48, and the guide hole 52 is centrally positioned on the jig panel 48. The guide hole 52 has a bounding edge 69 and the bounding edge 69 has a plurality of intersecting sides 70 such that the guide hole 52 has a rectangular shape. The guide hole 52 is spaced from the face 22 of the door 24 a distance corresponding to the offset of either the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20. The jig panel 48 has a pair of slots 71 each extending through the top surface 58 and the bottom surface 56. Each of the slots 71 extends substantially between the front side 62 and the back side 64 of the perimeter edge 60 of the jig panel 48. Each of the slots 71 is positioned between the guide hole 52 and a respective one of the first lateral side 66 and the second lateral side 68. Moreover, each of the slots 71 is aligned with a respective one of the first holes 44 or the second holes 46 when the jig panel 48 is positioned on the block 12.
The top surface 58 has a pair of channels 72 each extending toward the bottom surface 56 of the jig panel 48, and each of the channels 72 extends between the front side 62 and the back side 64. Each of the channels 72 is aligned with a respective one of the slots 71 and each of the channels 72 is oriented collinear with the respective slot 64. A pair of bolts 73 is provided and each of the bolts 73 is extendable through the jig panel 48 and the block 12 for attaching the jig panel 48 to the block 12. Each of the bolts 73 is extendable through a respective one of the slots 71 having the bolts 73 extending fully through the respective first hole 44 or the respective second hole 46 in the block 12 that is aligned with the respective slot 64. Each of the channels 72 in the jig panel 48 accommodates a head 74 of the bolts 73 when the bolts 73 are extended through the respective slot 64 thereby facilitating the head 74 of each of the bolts 73 to be spaced downwardly from the top surface 58 of the jig panel 48. A pair of nuts 76 is each threadable onto a respective one of the bolts 73 when the bolts 73 are extended through the jig panel 48 and the block 12 for retaining the block 12 on the jig panel 48. In an alternative embodiment 78 as is most clearly shown in
In use, the block 12 is clamped on the face 22 of the door 24 such that a selected one of the first set of mortises 14, the second set of mortises 16, the third set of mortises 18 or the fourth set of mortises 20 is aligned with the edge 26 of the door 24. The jig panel 48 is positioned against the edge of the door 24 such that the jig mortises 50 engage the block 12. Each of the bolts 73 is extended through the slots 71 to engage the respective first holes 44 or second holes 46 in the block 12 and the nuts 76 are threaded onto the bolts 73 to retain the jig panel 48 on the block 12. In this way the guide hole 52 is precisely located on the edge of the door 24. Thus, a router or other type of tool can be employed to carve out the hinge recess 54 in the guide hole 52, thereby precisely locating the hinge recess 54.
