Another way and the reasoning behind it.
If you want to cut a 2 × 6 into 2 × 1 × 6 Go to a timber yard and buy half the quantity you need of 1 × 6 as you will not get 2 × 1 × 6 from a single piece of 2 × 6.
You will get one at 1 " and another less than 1"
If that suits your purposes do a Keifer or L/W solution.
Otherwise save your 2 × 6 for a different project an lash out for the total stock required.
