STEP 1: Cut the Universal "B" Stop to the length necessary based on the length of your stud. For a 1/2" CD stud, cut the stop so that 1/4" of the stud is in the collet and 1/4" is protruding. You want to get as much of the stud into the collet as possible but you need at least 3/16" sticking out.
STEP 2:Place the Universal "B" Stop inside the collet, then install the collet in the gun shaft. Tighten the set screws.
STEP 4: Slide the foot piece assembly (CD foot and 2 CD Legs) into holes in the face plate. Line up the legs so the legs lines up with the face plate. Adjust so the CD stud sticks out past the foot 1/8" - 3/16" (the plunge). Tighten the set screws in the face plate.
