For all of my planning, I must admit there simply was no room in my shop for some tools. I struggled to find a place for my wide jointer and eventually decided against shoehorning it in, instead making a fixture for my router table that joints edges quite well. My scrollsaw, the bulk of my wood supply, and some storage cabinets didn’t make the cut either. These remain in a nearby room.
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.
