Tramming Discrepancy

5

Hey Erik,

the Mitz Pellicciotta method, which is a method that works the better the larger the bit diameter is, because it looks at the direction of the patterns such a bit makes when it is not perpendicular to wasteboard surface, works only as third step after you ensured your machine is

  1. rectangular (“squared”) (bar gauge) and 2. coplanar (“not twisted”) (fishing line method).

Only then I would proceed with

  1. Tramming the router (Checking for perpendicularity between milling motor axis and (different areas of) worksurface)

IMPORTANT NOTE: Surfacing the wasteboard does help nothing if the machine is not accurately rectangular (“squared”) and coplanar (not twisted)! Not at all! All your workpieces including the wasteboard will remain a parallelogram and be twisted if you don’t ensured steps 1 and 2 accurately.
