Abstract:
A method of using an adjustable angle cutting jig device for use with a table saw having a circular blade, a rip fence and a miter grove, said method comprising the steps of:obtaining the device consisting essentially of: rip fence guide having a first end, a second end and a back surface; a first shank having a distal end and a proximate end, the proximate end of the first shank is attached to the first end of the rip fence guide, the first shank and the rip fence guide are disposed substantially perpendicular to each other; a second shank having a distal end and a proximate end, the proximate end of the second shank is attached to the second end of the rip fence guide, the second shank and the rip fence guide are disposed substantially perpendicular to each other, the first and second shanks are disposed substantially parallel to each other; a first cross member attached to the first and second shanks; a second cross member attached to the first and second shanks; a first rotating arm having a distal end and a proximate end; the distal end of the first rotating arm is pivotally attached to the distal end of the first shank; a first threaded bolt attached to the proximate end of the first rotating arm; a second rotating arm having a distal end and a proximate end, the distal end of the second rotating arm is pivotally attached to the distal end of the second shank; a second threaded bolt attached to the proximate end of the second rotating arm; a cross brace attached to the first and second rotating arms, wherein the first and second rotating arms are disposed parallel to each other; a first angle guide having a distal end, a proximate end and a first collar, the proximate end of the first angle guide is attached to the proximate end of the first shank, the first collar defining a first curved hole, wherein the first threaded bolt attached to the proximate end of the first rotating arm is slidably engaged within the first curved hole of the first angle guide; a first wingnut threadedly attached to the first threaded bolt; a second angle guide having a distal end, a proximate end and a second collar, the proximate end of the first angle guide is attached to the proximate end of the second shank, the second collar defining a second curve hole, wherein the second threaded bolt attached to the proximate end of the second rotating arm is slidably engaged within the second curved hole of the second angle guide; a second wingnut threadedly attached to the second threaded bolt; and a first clamp; a second clamp; and a miter rail attached to the cross member, the miter rail dimensioned to slidably fit within the miter groove of the table saw; inserting the miter rail of the device into the miter groove of the table saw; sliding the rip fence of the table saw against the rip fence guide of the device; identifying a wooden board to be cut at a desired angle; loosening the first wingnut from the first bolt so that the first rotating arm is free to pivot; untightening the second wingnut from the second bolt so that the second rotating arm is free to pivot; grabbing hold of the brace member when the first wingnut is loosened and when the second wingnut is untightened; aligning pivotally the first rotating arm to the desired angle; aligning pivotally the second rotating arm to the desired angle; fastening the first wingnut to the first bolt when the first rotating arm is angled at the desired angle so that the proximate end of the first rotating arm is firmly secured to the first angle guide; tightening the second wingnut to the second bolt when the second rotating arm is aligned at the desired angle so that the proximate end of the second rotating arm is firmly secured to the second angle guide; raising the blade on the table saw; placing the board flush onto the brace of the device; adjoining securely the board flush onto the brace of the device with the first clamp; affixing securely the board flush onto the brace of the device with the second clamp; turning on the table saw so that the blade rotates; pushing the device with the board adjoined and affixed securely to the brace when the miter rail of the device is inserted into the miter groove of the table saw and when the rip fence of the table saw is slid against the rip fence guide of the device; and cutting the board at the desired angle when the device is pushed.
