If your lower has a (pretty) coating of any sort which is always OVER the hard coat, it adds typically 3+ thousandths on EVERY SURFACE WITH WHICH IT MAKES CONTACT. For clarification, and as an example, let’s think of this modification to a Leadstar PCC Techwell which installed by pushing the Techwell body up and on, then dropping the inserts down into the sides. On that one we would have to file the “Flat Sides” (see the first top left photo), so there would be that 3+ thousandths on EACH SIDE which needs to be filed. The Leadstar was one good example, here is another two examples; our “Slide-On” models ie. Gibbz, or Angstadt, would require the filing as demonstrated in the other three photos – “Upper Inside Edges”, “Lip Upper Angle”, and “Lower Flat Inside Edge”.
