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).
Some of the most important decisions in laying out a shop involve the placement of basic machines, such as the table saw and jointer. Deciding where to put them depends in part on the scale of woodworking you do, which determines the clearance area around these machines if you need to handle long stock or large sheet goods. You’ll also want to consider work flow to avoid an excess amount of running around the shop to accomplish tasks, as well as how to power your machines without turning your shop into a snakepit of extension cords.
