Plan to invest in a set of bench chisels, both standard and low-angle block planes, a No. 4 or 4-1⁄2 smoothing plane, and a No. 6 jack or No. 7 jointer. Between them, these planes will true edges, flatten glue-ups that are wider than your thickness planer, and tame tricky grain that would tear out with a mechanized planer. They also do fine trimming better than any other tools.

The router—The router is the master when it comes to flexibility. Its potential far exceeds trimming and decorative edge treatments. A router will cut mortises, rabbets, and dadoes, and adding a router table builds in even more versatility, including biscuit joinery and raised-panel doors. But where the router distinguishes itself from all other tools is in its ability to produce identical parts using a pattern.
Click the image at right, and start building the ideal workflow at the bottom where you see the first red arrow. This arrow crosses through one roll-up door of a typical two-car garage. Note that if the right-hand window were not present, you could place lumber storage closer to the entrance, which would also allow for easier passage onto the jointer. Work flows from the jointer to the planer and the table saw, then ideally onto an outfeed table near position #2 in the diagram. From #2, proceed left to the assembly area (pictured below).
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.
If you have a fixed-in-place cutoff saw (a radial-arm, miter saw, or sawbuck, for example), it can, unlike the table saw, be conveniently positioned against a wall. Don’t set it in a corner, however, as you’ll need space on either side of the blade. Figure into your plan a two-foot-deep, three-foot-wide space for the saw itself and tables or other supports flanking the tool. Allow enough space directly in front of the saw for the operator to be able to comfortably line up and operate the saw.
In addition to sheer power, look for a model with a built-in thermostat so you can set it and forget it. This convenience feature is well worth it so you don’t have to stop what you’re doing mid-project to manually turn your heater on and off to maintain your desired temp. A good garage heater will mount to the wall or ceiling to save space and will come with a durable housing and full safety screen to keep dust and wood chips from reaching the heating elements and starting a fire.
Impact driver: I am a giant fan of impact drivers. I have been using them for a while now and can’t really remember my life before them (Click here to read more about my introduction to impact drivers). This is the one tool that I always have with me, and I expect to be within easy reach. So much so, that I own three of them and could imagine myself with a couple more. Like the chop saw, if this was a list of on-site or installation tools, the impact driver would be near the top.
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.
