For one thing, the rearrange-it-later approach may simply mean that once you’re set up, the haphazard plan becomes the permanent plan, thanks to sheer inertia (it is a pain to move furniture, after all, especially when some of it is as heavy and awkward as workbenches and stationary tools). For another, too little advance planning may mean you buy a power tool that’s too big for your space.
I agree with all of these tips in a larger shop. In a smaller shop (mine is just under 400-square feet) most things are fairly close together anyway. One of my original principals for shop layout was … how is a machining process performed on a piece of wood? Is the wood stationary while it is machined … or does the wood move through the machine? If the wood is stationary, I have tried to have this set for one side wall of the shop. To be specific, I have four machines in one line with a continuous table to support long pieces that might need cutting from one or all of those machines. The machines in that line are (from left to right) the drill press, the powered miter saw, the square-chisel mortiser and the radial arm saw.

Always nice to see project ideas. Yet, to make a living while woodworking all projects need to be scaled up so that one can actually earn enough to survive and compete against the flood of Chinese imports and others. Substitute products made from plastic, metal or wood are a common place and normally cheaper due to mass production and human rights violations. Politicians don’t care about the disappearance of many of America’s Cottage Industries and most consumers don’t care as well.
In each case, we shuffled the bench, jointer, table saw, and band saw across to the top of the stairs, and then tied a rope around each to act as a safety while sliding the machines down the strapping on the stairs. Yeah, the table saw hit the wall, and the promise of a good mud and paint job saved my bacon. The rope worked well, and we were able to get everything down the stairs nice and slowly with­out any major issues.
After years of digging down under router tables, lifting the entire unit up to change bits, and then fighting to get the plate flush again in the table, I chose to spend the money to pur­chase a router table, fence, and lift system. I did a thorough review of these systems, and chose the Canadian made Jessem Rout-R-Lift II kit. The system comes with a solid steel stand, a phenolic table, an adjustable extruded aluminum fence, and their base model lift system. For budget reasons, I did not choose the hefty Mast-R-Lift, but I am quite happy with the lighter Rout-R-Lift II. It will last me a couple of lifetimes, so it is the right system at the right price for me in my one-man shop. Hats off to Jessem for making a great lift at a very rea­sonable price in the middle of a tough economy. The table is durable, and flat. The direct drive lift is smooth and precise. I mated the lift system to a mid-sized model 690 Porter Cable router, which has a fixed speed, and enough power to do any­thing I need. The Jessem system uses a bayonet type mount for the table inserts, a nice touch that makes swapping the table insert quick and simple. As with all my machines, the router table is connected with the supplied dust port to my shop dust collection system with automated switching. 
A shop geared toward woodworking would have lumber storage located at one corner of the triangle. Storage space for wood — both long pieces and flat plywood pieces — should be adequate. Raised storage, such as racks or shelves mounted on the wall, must be sturdy. Wood storage should also be in close proximity to the stationary tools or machines (table saw, jointer, power planer, etc.) to avoid frequently carrying heavy wood across the span of the workspace. Wood storage should be handy and near the area where the heavy woodworking tasks will take place. Keep in mind that a considerable amount of space will be needed around stationary tools such as a table saws and jointers for manipulating large pieces of raw lumber.
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.
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!).

In general, a table saw requires at least eight feet in front and behind to accommodate standard sheet goods and four feet side to side. A work table should provide four feet clearance on all sides, and pathways between tables, benches and storage units should be three feet wide. Proper clearance will allow you to move about with ease while you work.
When you design your workshop setup, climate control often gets ignored — and that’s a huge mistake! If your workshop or hobby room is in an unconditioned space like a garage or basement, you could find that it’s brutally uncomfortable to work in there during warm weather. You’ll be much happier with a solid fan — or several — to keep air moving for your comfort.
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).
Once the workshop location is determined, it's time to begin planning how to lay it out. First, acknowledge the need to formulate a plan that's realistic in terms of the space allotted. The size of the structure or workspace will place some constraints on how much can be done. Taking into account size limitations, begin fashioning a plan that keeps efficiency in mind.
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.
This is a fundamental question. A good place to start is with a survey of your property. Most municipalities have a maximum percentage of your lot that you can build on and standard setbacks from your property lines that you will need to adhere to without needing to request special permission to build. On a photocopy of your survey you can draw in what your local setbacks are in order to define the location within which you will be permitted to build. In a best-case scenario, you will have the space to build without compromising too much on space or location; otherwise, you may need to request a minor variance, which would allow you to circumvent an obsta­cle such as a setback.
My advice here is to make a detailed list of what the various parts of the build will be (drawings, permits, foun­dation, framing, electrical, etc.) and decide what you would like to do yourself and what you will need to hire others to do. Get quotes on the work that you would like to hire out and estimate the materials you will need to do your por­tion. You may want to factor in your time into the cost as well, especially if you will be passing up other income to work on the project. At some lumberyards, you will be able to give detailed drawings to an estimator on staff who will do a material takeoff list for you of what you’ll need and what it will cost. When all the numbers come in, you can put together a budget and plan for an overrun allowance of around 15 percent. If you keep track of the materials and subcontract costs as you go, you can stay on track and make decisions as you go about the latter stages of the project without regretting it later. If it is challenging to obtain fund­ing for a complete build, you may want to stage the build so that initially the frame goes up and the exterior is finished, and then you finish the interior work as you have time or as funds become available.
Not happy with the selection of sanding blocks at the hardware store, I made a few of my own from hardwood scraps left over from a woodworking project. I cut each one to 3/4 in. x 1-1/2 in. x 4-1/2 in.—which is just the right size to wrap a quarter sheet of sandpaper around. And the “kerf” cut helps hold the sandpaper in place until I’m ready to change it. —Tim Olaerts. Here are 41 more genius sanding tips you need to know.
Finally, think about the overall color and feel of your workshop. A fresh coat of bright white paint will help your lighting go farther, but you might also consider adding a splash of color for fun. An accent wall or an epoxy floor coating are good ways to upgrade your workshop from drab to fab without adding fussy decorations that will get in the way of business.
Even if you buy your lumber already planed, you will still encounter many circumstances that require the use of a planer. For example, you might want to build a simple and delicate jewelry box out of small scrap pieces lying around the shop, and you will end up making a small and clunky jewelry box because all of your lumber is 3/4″ thick, and that’s how it is going to stay. That is just the first example. Think about all of the other times that you will pick up a piece of lumber in the shop and it will be the wrong thickness, either just slightly wrong or in an entirely different size category. A planer is a real problem solver and can fix all of that.

To plan my shop, I used a modeling program on my computer, but you can use the drawings I created to plan an efficient shop on paper. Download and print the PDF below and arrange them on graph paper to create a plan view of your shop. Take the time to work out the most efficient placement of benches, cabinets, and machines, taking into account infeed and outfeed zones as well as ducting for dust collection.

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.
