There are benefits to either approach. Sharing a common wall with your house can require some careful soundproofing but can reduce heat loss and exterior fin­ishing costs like siding. A shop located in an addition is more likely to be allowed to have living space or storage space above it, and it may be easier to make use of the existing plumbing and electri­cal and heating systems of your home to service your shop space. Another advantage of an addition is not having to run to an outbuilding in minus-30-degree weather or a summer downpour.
Lacking a jointer? Use reader Court Kites’ awesome tip to create perfectly matched glue joints on wavy or bowed board edges. Lay the boards on a flat surface, then clamp them across the middle with a bar clamp. Lay two 8-in. long by 1-3/4 in. wide scrap boards across each end and screw them in with four 1-1/4 in. long screws, two per board. Keep the screws well away from your future cutting line!
To experiment with different wood shop layouts, measure your furniture and equipment to sketch onto your plan in different positions. You can also make cutouts of the footprint of your items so you can easily move them around your floor plan to see how best to arrange them. As you do so, don’t forget to leave adequate spacing around tools and tables.
“I do a lot of finish-sanding freehand, without a sandpaper block, so I can smooth edges and get into nooks and crannies. But the finer grits are usually bonded to thinner paper and, at least for me, the paper is too thin and ends up tearing long before the grit wears out. So I apply duct tape to the back of the sandpaper. The sandpaper is still flexible enough to sand a tight radius and it’s far more durable. You can use this super-strong sandpaper like a shoeshine rag.” — Chuck Merchant

If your shop will be attached to your house or another struc­ture, it will likely need to match its foundation, tying the two structures together so that one does not structurally stress the other if they shift differently. That may dictate a poured concrete or concrete block foundation. Regardless of your foundation type, a cold concrete floor will sap energy away from the rest of the structure if you are not careful, so think about how to insulate it well before you build.
Clamping up four mitered corners is tricky. You can buy specialty clamps for this, but I make my own. Here’s how to do it. Start with a long 1×4, as it’s easier (and safer) to clamp for making the angled cuts than a short piece. Mark out the blocks, and then drill a 1-in. diameter hole in the center of each one. The hole prevents the blocks from getting glued to your project. Cut 45-degree angles tangent to the hole, and then cut the blocks free from the long board. We’ll walk you through how to make one for your home shop.
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.
