This step-by-step procedure for fitting a drawer comes from Rob Porcaro's years of experience making furniture. The key is that it does not compound errors as you move through the steps, but rather eliminates them. From the first step of tapering the case slightly to make it slightly wider at the back, to the process of fitting the drawer front to its opening, to cutting the dovetails, Porcaro guarantees his procedure will get you a great fitting drawer every time.
