Raise your blade up to the thickness of the board you are cutting, that should line up the sides. If you are using a router, have the lowest part of the bit at the thickness of the board. I think I got all that right. I’m betting someone will be along shortly to straighten both of us out with the correct answer. -- They say many people die because of alcohol.

Blade/cutter height is what matters. -- Gerry -- "I don't plan to ever really grow up ... I'm just going to learn how to act in public!"

He wins the prize today!You can use any width you choose but the height of the cutter (whatever you choose to use) has to be the thickness of the wood.
