You sure make “keeping up with the Spagnuolo’s” tough. :) The cart fits my space pretty well. I am somewhat limited so utilizing the space under the lumber rack works well for me. I have the stand alone scrap storage bin also but the extra scrap storage on the cart is a bonus. I always seem to have srcap lumber running out of my ears. I have a hard time throwing away even a small piece of walnut or other nice (expensive) wood.
If your shop is long and narrow, option 2 provides maximum space to the left of the fence for handling large sheets of plywood. If you often work with full sheets of plywood or other sheet goods, you might want to build the table saw into an extension table surround, as San Diego woodworker Pat Curci did in his small shop (see the photo). The surround offers support for large panels, as well as provides an ample work surface near the 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.
