Timely article indeed. I’ve been playing with the shop layout tool on Grizzly’s website (http://www.grizzly.com/workshopplanner) which helps you see how tools fit in a specific shop size. However, your insight and experience really helps with ergonomic considerations. When I first built my shop, the first thing I did was installing a wall mounted work bench – as my fore fathers had all done – Big Mistake! Soon-to-be project: ripping it out and building a mobile work bench on wheels (like the one you have pictured).
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.
