I agree that I might quickly outgrow a 12x8 shed. Lowes also offers a 12x10 Rancher (same style, but more room), but the 12x10 is 9 feet, 4 inches high, and my community only allows a maximum height of 9 feet. The 12x8 is exactly 9 feet high. I'm afraid of getting "out of spec" if I exceed the height limit and then getting in trouble with the Home Owner's Association. Having said that, 12x10 would be about the biggest size I could get for the available area in my back yard, so even if I hire a shed contractor to do this, the shed would have to be 12x10 or smaller.
Traditionally woodworkers (joiners) learnt their craft working as an apprentice in the Master Craftsman's shop doing the grunt work and learning by assimilation over many years. Our approach is a little different. We're making the assumption that you're smart; are developing or already have a passion for woodworking; and can devote three months to intensive learning.
I’m building my second bench. I built the first years ago with wood from old machinery pallets – mostly oak and maple. Mortised the legs into the base, and pegged ’em with 1″ dowels. Of course, the legs warped a bit, but that made everything tighter and stronger. The top is 2″ thick Ash, one board cut in half and joined side to side. Wrapped a maple apron around the top, and I think I screwed the top from underneath to the leg braces. Solid. Over time, built a cabinet under for 3 drawers and a small cabinet door. Works for me.
Synopsis: No room in the garage? Basement not an option? Consider what Ken St. Onge did when he needed shop space: He bought a prefabricated shed and converted it into his full-time woodshop. Because a pre-built shed doesn’t need a cement foundation and is built in a factory, it’s much less expensive than building an addition or stand-alone shop on your property. It can have taller ceilings than a garage and bigger doors than a basement, both big pluses for a woodworker. You can put a shed just about anywhere, too. Here’s a soup to nuts look at Ken’s experience, so you can gauge whether a shop in a shed is right for you.
