Method 1 - practical geometry method:

1. get an s4s board.

2. face cut board along one side with?a square edged cutter like a rebate with shaper indicated at square.

3A. Crosscut board, flip one of the pieces upside down and see if the edges match, make a ^ or make a V.?

3B. Alternatively, you could also not cut the board in half, but flip it upside down directly against the cutter

4. Measure the clearance and adjust it out with the "0" stop over successive passes.

Method 2 - QUICK SHOP METHOD:

1. Skipping steps from Method 1,? take the S4S to the cutter same as #4 above, and adjust angle until it kisses the square edge squarely, then reset your zero marks on the dial or the dro and now you are in business regardless of whatever is causing the system to be out of alignment. Live to make a dollar another day.

Method 3 - Expensive tools method:

1. Calibrate dial indicators and make or use special mounts to measure cutter offset against reference plane.

2. Adjust.

3. Be proud of yourself you just got it within 0.0001"

4. Make a test cut and realize you forgot to consider a particular variable.

5. Buy or build more expensive tools for a niche purpose.

6. Repeat 1-5 until the initial issue is resolved. Repeat step 5 until your mood is resolved.?
