If you’re making two cuts from the same board, here’s a circular saw DIY tool tip that will save you time.
When measuring and cutting two pieces from the same board, it’s easier, faster and more accurate to measure from each end toward the center than it is to measure from one end.
One reason for this is that there’s no way to account for the thickness of the kerf of the circular saw blade if you measure from one end. So no matter what you do, one of your cuts will be short. Pull from both ends and get it done fast.
