Depending on your situation, you may need to upgrade to 200 amp electrical service in order to meet the needs of your house and your shop. It may also be in your interests to add in a separate electrical service meter on your shop so that you can clearly write off electrical use for your business, or in future rent the space out and clearly separate out the utilities for bill­ing your tenant. Generally, you don’t want to skimp on the power to your shop or on the lighting you include.
Line ’em up — Most other woodshop machines work harmoniously when lined up along the walls, where they are easy to power and connect to dust collection. The amount of space left between these tools depends on the amount of room you have, the size of the stock you work with, and whether or not adjacent tools have tables at the same height. You can always pull a machine away from the wall if additional space is needed. Clearly, these options are not the only possibilities and are contingent upon the mix of machines you have, the shape and size of your shop, and the kind of work you do. The bottom line is if the layout works for you, then that’s the best for your shop (and don’t let anyone tell you any different!).

These are all good tips, and apply to pretty much every shop. Like all things woodworking they need to be tweaked so that it’s right for the individual. For instance, I have a basement shop that’s not tiny but it is still space constrained, so worrying about the optimal layout for my ts/jointer/planer is a little off the mark since I don’t have to walk very far; instead, I want to be sure that related tools can be used *at the same time*. Having to move the planer out of the away so that I can use my TS is crazy if it can be avoided. However, interference between my drill press and my planer is less of an issue because they usually don’t get used at the same phase of a project.
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.
