This section shows how to shape the Lugs
Important: The 6152 has added metal to the top surface of the Lugs. This is so that you can shape the lugs to the desired dimensions, to give the "step" you see in the images opposite. Remember, try not to remove too much metal, if you want to remove more you can always do this later.
Below: I am going to use a small fine/medium flat file. Note the edge of the file, make sure that the smooth side is the side you use near the top surface of the case.
