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 squ are 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 fe nce 90 degrees to the direction of sled travel.
If the table saw blade were a cutting laser projecting 90 degrees to the ta ble, 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 t rue.
Am I missing something? I know it's picky but it makes me cringe when peop le make that claim.
