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.
Natural Light. Natural light is best, so any windows that offer illumination to the space should be put to good use. If you have little sunlight in your shop, locate your workbench so that its work surface gets whatever there is. Even the best eyesight is made better by good light, so the close work to be done on a benchtop benefits from the natural light.
Let’s face it, one of the most significant costs of your shop will be its foundation. While you’re at it, what about adding space above your shop? There may be regulations preventing you from building living space above your shop if it is in an urban setting or in an outbuilding, but there may be some flexibility depending on where you live. It is in the municipality’s interests to encourage infill housing that uses existing infrastructure. At a minimum, think about including attic trusses to create some space above your shop for drying lumber or storing equipment. Access could be from simple pull-down attic stairs or from the exterior if you don’t want to lose floor space to a stair or ladder. If you’re creating an addition to your house, you may be able to add a couple of rooms you’ve always wanted, such as a family room, office or in-law suite.
First, let’s take a look at four placement options for the table saw, the machine that is at the heart of most woodshops. The first option (see the illustration) places it in the center of the shop, which lends maximum space and flexibility for ripping and panel sawing, as well as crosscutting long boards. The main requirement here is a shop that’s at least long and wide enough to allow room for the workpiece, both on the infeed and outfeed sides.
