I agree with all of these tips in a larger shop. In a smaller shop (mine is just under 400-square feet) most things are fairly close together anyway. One of my original principals for shop layout was … how is a machining process performed on a piece of wood? Is the wood stationary while it is machined … or does the wood move through the machine? If the wood is stationary, I have tried to have this set for one side wall of the shop. To be specific, I have four machines in one line with a continuous table to support long pieces that might need cutting from one or all of those machines. The machines in that line are (from left to right) the drill press, the powered miter saw, the square-chisel mortiser and the radial arm saw.
Let’s be clear about one thing: No workshop is perfect for everyone. If there were, I could simply give you a precise plan to follow with clear dimensions. Every person who comes to the hobby, avocation, or profession of woodworking has his own particular collection of tools and his own peculiar work style, skills, and desires for the kind of woodworking he wants to do that gives him a unique approach as to how he will lay out a shop: where the tools should go, where lumber and supplies are stored, and how much bench area he needs.
