A receptacle or circuit that is overloaded is a hazard, in particular one fused beyond its limits. Power tools, especially heavy-duty saws, require lots of amperage, and you may need to add a circuit or two to serve the increased demand in your workshop space. Some tools re­quire 220-volt service, so you may want to install a special plug and line to power that high-powered table saw.
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.
If your table saw is near a wall and your shop is fairly narrow, positioning the jointer and planer against the opposite wall is reasonable, as shown in option 2 in the illustration. If the shop isn’t long enough to accommodate long workpieces, try to put these machines near an operable doorway, as shown in the illustration and in the photo of Doug Warren’s shop.
High-velocity fans are also an important tool in their own right, particularly at your finishing station. Increased air flow will help dissipate fumes from paints and sprays for your safety, and you can train a fan on your project to help paint dry more quickly between coats on humid days. To get the most out of your fan, look for floor fans that are easy to aim or wall-mounted fans that will save space in smaller shops.

If your shop lacks wall space or doesn’t have a long enough wall to accommodate long stock, another option is to place the crosscut saw near an operable doorway with the right-hand side closest to the door (see option 2 in the illustration). This leaves most of the length of the fence to the left of the blade (preferable if you’re right-handed), allowing short and mid-sized parts to be cut to length or trimmed without having to open the door.
For many of us, the moment we learned that a 2×4 board is actually 1.5 inches x 3.5 inches was simply mind-blowing. The reason for this apparent contradiction is that the board has been planed down to eliminate irregularities. At one point, many years ago, 2x4s actually were 2 inches x 4 inches, but their rough surfaces made them difficult to stock and handle. The old terms, such as 2×4 or 4×4, are still used, and are known as the “nominal” size of the board. These nominal sizes are used because they are easier to say and they stick to tradition. Now, thanks to a lawsuit, most big box stores list the nominal and actual sizes of lumber.
If you choose to hire a draftsperson or architect, they may charge you based on the square footage of the area you are proposing, by an hourly rate for their time or as a percent­age of the cost of the structure. Costs of building permits will be a percentage of the estimated cost of the structure you are proposing (e.g., $15 permit fee per $1000 or 1.5 percent), or a cost-per-square foot depending on your municipality (e.g., $1.20 per square foot). Design work and permits will both dif­fer depending on the part of the country in which you will be building, so ask the questions as you move ahead. One of the costs that is often overlooked in planning is the increase in annual property tax you will pay once your improved property has been reassessed.

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.
