       6 . The threshold jig according to  claim 5 , wherein the first adjustable slide bar includes a first segment and a second segment connected by an offset segment. 
   
   
       7 . The threshold jig according to  claim 1 , wherein the first jamb stop head block is provided with a center point indicator mark. 
   
   
       8 . The threshold jig according to  claim 1 , wherein the first jamb stop head block is provided with a semi-circular recessed area allowing for controlled pivoting of the first jamb stop head block relative to the respective the first slide bar. 
   
   
       9 . The threshold jig according to  claim 1 , further including a thumb knob securely holding the first slide bar to the first jamb stop head block. 
   
   
       10 . The threshold jig according to  claim 1 , wherein each of the first pivoting adjustable stop block and the second pivoting adjustable stop block of the first jamb stop head block includes a relatively large central opening through which a bolt of respective thumb knobs passes for selective tightening thereof and permitting relative movement of the first pivoting adjustable stop block and second pivoting adjustable stop block upon the first jamb stop head block. 
   
   
       11 . A threshold jig, comprising:
 an adjustable mechanism platform including a first slide slot having an elongated recess and a second slide slot having an elongated recess;   a first slide bar positioned within the first slide slot and a second slide bar positioned within the second slide slot;   a first jamb stop head block pivotally secured to a free end of the first slide bar and a second jamb stop head block pivotally secured to a free end of the second slide bar;   the first jamb stop head block includes first and second pivoting adjustable stop blocks and the second jamb stop head block includes first and second pivoting adjustable stop blocks.   
   
   
       12 . The threshold jig according to  claim 11 , wherein the recess of the first slide slot extends outwardly in its width dimension as it reaches an edge of the adjustable mechanism platform and the recess of the second slide slot extends outwardly in its width dimension as it reaches an edge of the adjustable mechanism platform. 
   
   
       13 . The threshold jig according to  claim 11 , wherein the adjustable mechanism platform includes a cover positioned over the first slide slot and second slide slot, the cover maintaining the first slide bar within the first slide slot and the second slide bar within the second slide slot. 
   
   
       14 . The threshold jig according to  claim 11 , wherein the adjustable mechanism platform is further provided with a first adjustable thumb knob that is aligned with and passes through the first slide slot for selectively frictionally holding the first slide bar in position relative to the first slide slot, and the adjustable mechanism platform is further provided with a second adjustable thumb knob that is aligned with and passes through the second slide slot for selectively frictionally holding the second slide bar in position relative to the second slide slot. 
   
   
       15 . The threshold jig according to  claim 11 , wherein the first slide bar includes an offset head such that the first jamb stop head block is centrally positioned relative to the adjustable mechanism platform, and the second slide bar includes an offset head such that the second jamb stop head block is centrally positioned relative to the adjustable mechanism platform. 
   
   
       16 . The threshold jig according to  claim 15 , wherein the first adjustable slide bar includes a first segment and a second segment connected by an offset segment, and the second adjustable slide bar includes a first segment and a second segment connected by an offset segment. 
   
   
       17 . The threshold jig according to  claim 11 , wherein the first jamb stop head block is provided with a center point indicator mark, and the first jamb stop head block is provided with a center point indicator mark. 
   
   
       18 . The threshold jig according to  claim 11 , wherein the first jamb stop head block is provided with a semi-circular recessed area allowing for controlled pivoting of the first jamb stop head block relative to the respective the first slide bar, and the second jamb stop head block is provided with a semi-circular recessed area allowing for controlled pivoting of the second jamb stop head block relative to the respective the second slide bar. 
   
   
       19 . The threshold jig according to  claim 11 , further including a thumb knob securely holding the first slide bar to the first jamb stop head block, and a thumb knob securely holding the second slide bar to the second jamb stop head block.
