Insert a knife blade between the two plates and gently lift the top plate away from the bottom plate. If the correct angle has been used in sawing out the die, the die will reach a point where it wants to "hang-up" on the punch and not allow passage of the die. Use this resistance to help with the final alignment of the die to the punch. You may have to make the holes for the 10-32 screws a bit larger to allow this. When the punch and die are in perfect alignment, finish tightening all of the screws and add the two additional 10-32 screws as jam nuts.

After final alignment, and all bolts and screws are tight, grind off the protruding threads (and heads if necessary) of the 4-40 screws on both sides of the plates.
