Step 5: Base: Preparing and Cutting the Wood
Cut your board into appropriately sized pieces. Because it is easier to cut 2x4's than countertop material, I simply measured my piece of countertop and sized the boards to it. I was not particularly careful about this and you do not need to be careful about it, either. Just get things close.
NOTE: If you got your board out of the dumpster, as I did, you will want to be sure to get all the nails out of it, ESPECIALLY if you are using power tools to cut it. Pulling nails takes all of a couple minutes and means you get to save money on new materials. It prevents you from unnecessarily dulling or ruining tools. It is worth it.
