Since most of your assembly will be done on the assembly table, it just makes sense to have your clamps nearby. If you’re short on wall space, try a rolling clamp cart! If you use your workbench for assembly, keep your clamps near the workbench. Check out these two helpful articles for clamp racks: A Simple Utilitarian Clamp Rack and A Parallel Clamp Rack.

A good portable air conditioner will also remove excess water from the air, which is critical for keeping your stockpile of wood in good shape. Lumber should be stored in dry conditions so it doesn’t warp, so look for efficiency features that allow you to run the unit overnight in the summer as needed —without worrying about blowing up your electricity bills. Other good features to consider include a thermostat and variable settings that allow you to set your workshop temperature to the perfect level for your comfort.

One of the challenges in building a cabinet for hand tools, is that as soon as you define a place for each tool in your custom cabinet, you find that you need more room to store the must have tools you just bought. I decided to make a couple of open cabinets, and employ the use of inserts that can be replaced or modified as my tool collection grows. Part of the goal was to make a clean, efficient shop, while keeping to a budget. I bought paint grade maple plywood and made the cabinets. Applying a solid maple face frame to the cabinet makes a clean looking cabinet from sheet goods purchased at $50/sheet.
When I began to arrange my shop on paper and on the computer screen, I realized that, in a small shop, moving wood is easier than moving machines. So I ignored the idea of setting up the space for workflow—for example, creating adjacent, sequential zones for lumber storage, rough dimensioning, final dimensioning, joinery, and so on. That workflow concept is more appropriate for larger or commercial shops.
To make sure you account for any existing obstructions, it’s a good idea to make a measured drawing of your workshop area on graph paper, noting existing furniture, built-ins and large items on the plan as you go. For example, a common one-car garage workshop layout has built-in tool cabinets and shelves around the perimeter where they won’t impede parking, but you may also have to get clever about folding work tables and saw horses that you can set up as needed in the middle of the garage when you’re working on a project (and cars are parked outside).
Electricity. It’s a rare workshop today that doesn’t need electricity; most need multiple receptacles of high amperage (20 amperes or more). Are there plugs available or will you need to add new lines and circuits? If you need to add wiring, when laying it out keep in mind that there’s no such thing as too many outlets in a workshop. The fewer (as in, ideally, zero) extension cords the better; they’re safety hazards. A good minimum is to have receptacles set at no more than six-foot intervals around the perimeter of the room, and, if possible, flush-mounted floor plugs in the central area.
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.
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.
