Unless I am mistaken, it is a misconception to think that the 5-cut method squares your table saw blade to the sled fence.
What it really does is square your fence to 90 degrees of the direction
of travel (miter track). If the blade
was angled by a small amount the process would still align the fence
90 degrees to the direction of sled travel.
If the table saw blade were a cutting laser projecting 90 degrees to the table, the 5-cut method would still work.
Because this is true, the thought that the 5-cut method squares your
fence 90 degrees to a blade can not be true.
Am I missing something? I know it's picky but it makes me cringe when people make that claim.
I have always questioned the 5-cut process. If the blade were not
parallel to the fence.
I assume you mean perpendicular and not parallel.
the blade would cut a wider kerf.
Exactly. Analogous to a fatter or skinnier cutting laser. The process does NOT consider the squareness of the blade to the sled fence. Only that the process involves cutting.
Once the angle between the blade and fence became large enough I suspect
there would be problem.
Has any body tried to measure the parallelism by measuring the width of
the teeth on the blade, to the width of the kerf?
