Excellent job, John!! The cutting board looks nice, too. 
Something that wide (more than 6"s) can be a challenge.thanks Marco - first a block plane then the belt sander then rubbed it on a rough cinder block wall to fine tune it.
hey - it's not a piece of furniture, it's a "rustic" kitchen tool. (the key word is rustic).
I have a Dewalt 734 thickness planer, but it was under a bunch of "stuff" and since I only had to flatten one side, it was quicker to just rough it out by hand.
